Aluminum windows, not like vinyl and wood windows, will not crack, split or warp. The aluminum glass frame makes the windows and doors more durable and long-lasting. Aluminum is the sustainable development of green building materials.
Golden Jash supply professional and honest service.
The most common is the RAL color which has about 200 standard colors. Besides powder coat, Wellste Aluminium window profiles can also apply anodizing (polishing, brushed), PVDF, and electrophoresis coating for your selection.
Wellste Aluminium window profiles also can adopt high-quality thermal Break raw material as insulation bar, an insulation bar will be added through the aluminum section to create an insulated barrier to prevent heat conduction.
The material of the insulation bar is PA66 Nylon, which has good toughness and strength, thus it has a good insulation effect.
Compared with Vinyl window, Wellste aluminium window profiles has obvious advantages. Vinyl window cannot be painted, while aluminium window profiles can be powder coated to the color you want. The strength of the vinyl window is not so strong and weighs much heavier than aluminium window profile.
Aluminum window is lightweight with strong strength. Vinyl window cannot handle extreme weather and corrosion environment, while aluminum window can handle this, it has goods corrosion resistance, the aluminium window profile makes the window more durable and long-lasting.
What&#;s more, vinyl cannot be biodegradable which is not good for our environment, while aluminum is environmentally friendly that can be recycled. So today more and more people choose aluminum windows.

Aluminum window profile
These are sections made from aluminum material that provide secure foundation for the window glass unit.
Remember, any window design is made up of three parts, i.e., glass, fittings, and the profile.
Aluminum window profile consists of casements and frames, which bear the entire structure&#;s weight.
Side view of aluminum window profile
Using aluminium offers the following advantages:-
Aluminium window profiles come in a wide range of designs.
Each design can provide a solution for both light commercial applications and residential applications.
Thus, aluminium window profiles can be used to:-
The insulation creates a barrier between the warm air indoors and the cold air outdoors.
Thereby, decreases heat transmission, improving the window profile&#;s overall U value.
They are less likely to rot or warp compared to their alternatives. Moreover, aluminium window profiles are harder to dent due to their strength to weight ratio.
Different types of aluminium window profiles may require additional maintenance levels, but a fast clean often suffices.
The profiles will remain clean and gleaming if you clean them at least once every four months.
Types of aluminum window profile
The existing types of aluminium window profiles are:-
These aluminium window profiles feature beveled sightlines and 70 mm back to front dimensions.
They have opening sashes that may be side hung or top hung.
Besides, they are high-performance window profiles whose design best fits sustainable buildings.
They can also accommodate glazing units with 24mm-36mm thickness.
They conform to BS enhanced security standards.
These aluminium window profiles have similar dimensions to the aforementioned casement window profiles.
They are best for application in buildings with limited cleaning access. They have U values of 1.4W/m²K.
The window will protrude entirely outwards when opened.
They have a locking system and a hinge. As a result, the window can function as a tilt-in sash if the hinge is at the bottom.
These aluminium window profiles have a pivot hinge and restrictors.
They also have a relatively large sash size compared to the other window profiles.
The mechanical characteristics of aluminium window profiles are:-
Making aluminium window profiles comprises four different processes. The processes are:-
This initial stage involves the heating of the aluminium Ingot at a high temperature of about 700oC.
The heating results in molten aluminium, which is used in the subsequent stages.
In this next step, the molten aluminium metal is forced through a die. The die may vary depending on the desired end product shape.
At the end of this step, the aluminium window profile usually has a defined shape and ergonomic.
The extruded aluminium is cooled at room temperature.
Afterward, it is heat-treated while being quenched with water and rapid resistance to solutionize it without grain growth.
Special equipment is used for this process to ensure that the final product is strong.
The aluminium window profile windows are then surface treated to make them both wear and corrosion-resistant.
The elements dissolved in the aluminium will start precipitating after the aluminium has been heat treated.
This allows its grains to lock into place, increasing the profile&#;s natural strength and hardness.
The heat treatment process makes aluminium window profiles less likely to warp or dent.
Parts of window profile
There are many ways of cutting aluminium window profiles. Most involve the use of additional objects such as Dremel tools or handheld tools like tin snips.
Different tools have different grits to cut two or three different types of aluminium window profiles. Also, there are specialized machines used for cutting aluminium profiles.
Aluminium window profiles are not installed according to a standard minimal thickness of walls. Instead, their installation is done according to the window size, air pressure value, and airtightness of the window design.
There is no uniform standard for determining wall thickness to aluminium window profile characteristics.
The wall thickness of an aluminium wall profiles depends on the:
Interestingly, a single aluminum window profile can have a varied wall thickness, depending on strength requirement.
For example, to improve the profiles bending strength, you can make the areas away from the neutral axis thicker.
However, you cannot use aluminium profiles made out of thin aluminium extrusions for windows.
Generally, the common thickness maybe as follows:
The major quality requirement for Aluminium window profiles are:
Aluminum window profile
Aluminium window profiles are undoubtedly sustainable, easy to maintain, and durable. However, you must take into consideration other factors like the frame finish or accreditations and certifications that show product quality.
There are aluminium window profiles for both contemporary and traditional homes. These profiles have different designs in terms of thickness, colors, and finishes.
Aluminium window profiles are not obtrusive, and using them does not cost you any compromise.
There are also dozens of gloss and matte colors for you to choose from.
Aluminium window profiles are robust and durable. You should check if the product conforms to European or British security standards before you decide to purchase.
Also, check for certifications and accreditations that will show that the profile&#;s security measures are legitimate.
We combine clever design with sound engineering to provide you the best aluminium window profile options.
You should factor in your priorities regarding quality, security, and design to figure out your budget range.
Additionally, you should factor in additional costs such as installation and transportation costs.
The higher the quality, the higher the value.
An aluminium window profile die is a tool that we use to press heated aluminium alloy billets/blocks into finished aluminium profiles.
This tool heavily influenced how the final product looks like.
The die is a circular and thick disk made from H13 steel. It extrudes three shapes, i.e., hollow, semi open, and solid aluminium extrusions.
Additionally, aluminium window profile dies are hear treated. Meaning they can withstand high temperature and pressure involved in the extrusion process
There are different types of dies. Each creates a different type of aluminum window profile mould. There are solid dies, hollow dies, and semi-hollow dies.
A solid die extrudes a shape without openings or enclosed void. They are less expensive.
A hollow die creates a profile with avoid. A semi-hollow die, on the other hand, produces a partially hollow shape. They are more complex and expensive.
The process of aluminium window profile extrusion causes uneven pressure and build-up of heat on the die.
This reduces the die&#;s longevity. Eventually, the dies become useless.
However, specific design choices can impact the tolerances of the die and increase its lifespan in the long run.
Aluminium window profile tolerance is critical because they affect system installation and heat transfer coefficients.
There are tolerances for various aspects of the aluminium window profile, e.g., thickness and straightness tolerances.
Aluminium window profiles are very complex in design. Hence, it can be challenging to specify the tolerance levels.
We are open to special agreements to reach the guidance standards for aluminium profiles.
The aluminium extrusion we use to manufacture the profiles meet the tolerances dictated by BS EN 755-9:, i.e., -/+ 0.2mm- -/+0.5mm. These are subject to enhancement if you require increased or specific tolerance.
Yes. Sometimes you may need to check the dimensions to make sure they are of the correct measurements before you go on a bulk run.
Doing so will prove the dimensions and design of the aluminium window profiles. Meanwhile, we will hold off the bulk run until you feel satisfied.
We have a large stock hold of aluminium window profiles. However, if you require specific design and dimensions, you should adapt to a longer lead time.
Unlike other window profiles, e.g. PVC, aluminium window profiles take relatively long to be manufactured. This is due to the sophistication of the process.
Therefore, the standard lead times are 15 to 20 days for a standard white finishes and up to 6 weeks for custom finishes.
Yes, we produce prototype parts for aluminium window profiles. We have many machining, tool/die, and fabrication capabilities.
This allows us to cost effectively and quickly manufacture window profile parts.
Besides, our process involves extrusion tooling which, is a relatively cheap process. It is best for you to buy an extrusion die.
To speed up the process, you can supply a solid or electronic drawing of the prototype you desire.
Currently, we accept Computer Aided Designs(CAD) files or solid prints of what you desire.
Aluminum window profile
Since standard aluminium is a heat and cold conductor, you can gain or lose a lot of heat through the window profile.
This may compromise the efficiency of double glazed windows in the long run.
Thus, the profile has to have a thermal break added to it.
A reinforced Polyamide bar is added between the outside and inside the aluminium profile to form an insulated barrier.
Thermally broken aluminium window profiles conduct cold, heat, and sound slower than regular aluminium window profiles.
We manufacture aluminium window profiles with a wide variety of aluminium alloys. These alloys come in different states and each has its distinct features.
We do this in order to conform to the expected standards for window profile application.
We manufacture aluminium window profiles as requested. You can choose the available options from our Aluminium a Series.
Alloys can be joined together with insulating material, e.g., Polyamide enabling you to use them in applications where you require thermal insulation.
Pricing is done on a weight per meter basis.
Aluminium extrusion weight per meter is calculated from the surface area of the extruded profile. Extruded aluminium profiles come in an infinite range of shapes and sizes, so the aluminium extrusion weight per meter is used to calculate the £/kg cost.
To simplify matters, we typically use the aluminium extrusion weight per meter to calculate a cost per piece, so you know exactly what you&#;ll be paying for each production run. If needed, we can also apply cost units of E/kg and £/meter.
If you have any particular cost requirements, or you&#;d like to know more about how we calculate our aluminium extrusion weight per meter, please let us know.
We will be happy to talk you through any questions.
We offer aluminium window profiles in varying width frames and thickness to accommodate the different types of applications.
Contact us to discuss your requirements of aluminium profile for windows. Our experienced sales team can help you identify the options that best suit your needs.
The standard sizes of the parts are usually the following dimensions:
Ageing for aluminium window profiles is the transformation of supersaturated aluminium solution into precipitate particles.
The main reason for ageing is to improve the mechanical properties of aluminium, e.g., tensile strength and hardness.
Precipitated give aluminium alloys their mechanical features, which are essential for window profiles.
It is also important to note that the strength of the aluminum profiles can be increased by adjusting the aging process.
Typically, using lower temperatures for a longer time will increase the formation of a stronger metal matrix.
It will also reduce the amount of dislocation while the aluminium profile is in use.
Using lower temperatures prevents the occurrence of over-aging.
Partly because it stops the precipitate from growing too quickly thereby increasing the final strength of the profile.
Anodized aluminium window profiles are easy to maintain.
You can clean them regularly with mild detergents and water to get back their lustre without the anodic coating flaking or peeling off.
With powder coating, you will notice orange peels, especially if applied too thick/thin.
Powder-coated aluminium window profiles come in a wide range of colours, from satin to gloss finishes.
Anodized aluminium window profiles are only available in polished and matte finishes.
Powder-coated aluminium window profiles aren&#;t as vulnerable to acidic pollutants as anodized aluminium window profiles. They have good resistance to chemicals and alkaline cleaning compounds.
Regardless of the type of aluminium window profile you chose, you should ensure that your supplier is reputable.
We have a proven quality assurance track record at each stage of our aluminium window profiles manufacturing process.
Double glazing aluminium window profiles keep mould from forming in the interior.
Humidity can cause mould to form inside structures, thereby causing complications like asthma attacks and infections.
Double glazed aluminium window profiles are very bad conductors of heat, sound, and cold. The Polyamide thermal break gives them such properties.
Poor heat conduction and dissipation also make them energy efficient.
Double glazing aluminium window profiles enhance security and safety.
Thus making them safe for environments with children and against break-in burglaries.
The natural finish of aluminium extrusion as they are extruded from the extruder die tool is the mill finish.
When exposed to moisture or air, mill finish aluminium window profiles will oxidize with aluminium oxide powder.
The mill finish aluminium window profiles can be painted or field primed to specific requirements.
They are shiny and almost mirror-like, with manufacturing lines that can be seen.
Custom sized aluminium window profiles are profiles made to your specific requirements that are not considered industry standards.
On the other hand, standard-sized aluminium window profiles are on offer from our catalogue.
We ensure that the assembly of the aluminium window profile is conducted on an elevated working surface.
The surfaces are padded to keep physical damage and scratches from the window profile.
These surfaces enhance accurate cutting.
Alternatively, we also use crimping machines to connect the mitre joint of the aluminium window profiles.
Screw joints are also a method of ensuring dimensional accuracy that we use. After assembling the entire aluminium window profiles, we use sealants to seal the screw holes and screws.
Our aluminium window profiles are sturdy and can support glass panes with weights of up to 500kg.
This makes them applicable in diverse areas, e.g., applications that provide abundant natural lighting.
We conduct quality inspection tests by ensuring that each profile configuration corresponds with the die design.
We conduct visual checks on the aluminium material to determine if:
During the production stages, we ensure the following:
We also conduct preliminary tests and inspections on materials before we greenlight them for usage.
We especially inspect and keep records for levels of accuracy and precision of the equipment we use.
Finally, we conduct inspections on the production sections to ensure that they meet the required benchmarks. We check the cutting, glazing, sub-assembly, and final assembly sections.
Once the manufacture is complete, we will lay down all standards met in reference to the required standards.
Yes. We offer our help in designing aluminium window profiles that can work best for your application and your standards.
Yes, to show our confidence in the quality of our product, we offer warranties. The aluminium window profiles have a warranty that covers defects arising from craft, materials, or manufacturing.
Our aluminium window profiles finishes will not blister, peel, or crack under appropriate applications, hence the fade resistance warranty.
All the above are warranted for not more than ten years.
Your warranty may be voided if the damage arises from modifications and improper installation.
Service/freight trips and taxes are excluded from our product warranty.
Aluminum window profile
Yes. Aluminium window profiles can be recycled. Aluminium material does not deteriorate in quality regardless of how many times it gets recycled.
Once rendered inapplicable, aluminium window profiles can be melted and cast into new aluminium window profiles.
Process coated aluminium materials like the ones we use in our window profiles are 100% recyclable and environmentally friendly.
This can be done by decorating the profile first using complimentary equipment before melting.
You can follow some of these simple processes:
Clean the profile periodically using a sponge or tiny soft cloth with a bit of detergent. Doing this properly will inhibit pitting and oxidation levels.
Dirt can accumulate in your window profile during dry seasons. Additionally, applying a sealant will prevent leaks.
Use light lubricants when you start to notice aluminium window profile stiffness.
To preserve the durability and performance of your aluminium window profile, you should do this regularly.
Be on the lookout for signs of deformity and damage and repair while you still have it in control.
Avoid using strong cleaning products that contain chemicals or bleach.
Methods for mechanical joining of aluminium window profiles are:&#;
We cater for each joining mechanisms in the design steps. The joining mechanisms are:-
This mechanical joining method features a releasable connection. They come in three variations, i.e.,
For the specific application of aluminium window profiles, screws with stainless steel heads are used. They are also corrosion resistant.
Transverse or longitudinal grooves or screw channels are used.
Screw joints are also a method of ensuring dimensional accuracy that we use. After assembling the entire aluminium window profiles, we use sealants to seal the screw holes and screws.
These are also called rebates. The width of the fold is important. A seam that is too thin is weak and might cause a lot of problems. A fold that is too wide results in sheet material wastage.
There are two methods of riveting aluminium window profile joints, i.e., direct and indirect methods.
In the indirect method, an extra rivet is used to join two indirect parts in addition to primary rivets.
The types of rivets used in aluminium window profile joint connection are:
The accessories that you will need for aluminium window profiles are:-

23 Jan 12 07:23Hi,
I am looking for research tips, all the possible notes and calculations on Moments of Inertia and Deflection for Aluminum Doors and Windows (Casement and Sliding).
I have the cad sections, the moments of inertia already calculated for the sections as well as section modulus. From this, I want to interpret and apply those basic calculations to determine height and width limits for the doors and windows.
The aluminium aloys is or ALMGSIO,5 with young modulus 70,000 MPa.
I have to draw graph showing dimensional limits as per wind pressure of 800 pascals, pascals and pascals, somtimes more. The Deflection is 1/150 (What does that mean?)
The main problem is that I have only seen those calculations in a few french-based catalogues and the few verbal explanations I received seemed illogical and so far not a single data on the net.
Any hints will be of great help.
Regards,
Nicolas.

23 Jan 12 12:29While you can do a simple (or even complex) structural analysis for this - my experience is that these companies test the "He$$" out of them to get verified and best results possible in order to qualify for storms, hurricanes, etc.

23 Jan 12 14:34How would you do the simple structural analysis? Where would you start given that you have the cad profiles, the moments of inertia on both x and y, the section modulus, the weight, the area, the centroid to name but a few?

How do you want your college engineering degree, in one paragraph or two? We'll send it right out. Those basic calcs. are a first year college engineering problems, with a bunch of engineering and product experience, judgement and testing thrown in for the final solution, tabulations and graphs.
A few CAD profiles do not an engineer make...., and you shouldn't need your CAD program to calc. the section properties either. I'd suggest you get a couples text books on Engineering Mechanics and Strength of Materials and study them, or take a few courses on these subjects if you are going to do this kind of work. Alternatively, go to a senior engineer or your boss for this kind of help, they should know what you know and what you don't know, if for no other reason than to keep you and the company out of trouble. Those kinds of local mentoring experiences are almost always more meaningful, rewarding and lasting than coming here for this level help, or the quick answer. If you can run a CAD program these probably are problems which you could do with some ongoing help from someone right at your company, so they can watch your progress and correct you quickly when you are going astray. They have a vested interest in seeing you do well and in seeing you doing your work correctly.

25 Jan 12 22:45Hi,
The very least I need is tips for research. I have number of structural, mechanical engineering books as well as 2-3 books on Strength of Materials. The issue is that I found moments of inertia application wrt to openings nowhere in those books, nowhere else. How come?
I have serious doubt on just adding profile inertia and insert in an excel sheet and the graphs popping up. I don't want to just do that without having a deeper understanding on the application.
Regards,
Nicolas.

26 Jan 12 15:23Might be second year engineering!! Moments of inertia are easy to calc or find a program to help you.
TRY Google. Me thinks you might be in over your head and need to seek professional help....

The reason you are having doubts and troubles, is that you apparently don't understand your own problem at a fairly fundamental level. While you may have some books, it appears that you haven't bothered to studied them to really understand the subject. While you may have a CAD and EXCEL program they won't do you much good either if you don't have the fundamentals down pat. They might help you do engineering, but they don't make you an engineer, and they won't do engineering for you if you don't know what you are doing. Given your level of questions, you have to do some serious studying on you own, or get help from your boss, because we don't teach elementary engineering fundamentals at E-Tips. You are probably not going to find a solved textbook problem that exactly addresses your situation. You have to use some engineering intuition, imagination, judgement and experience to understand how to break this problem down into its simplest parts, and then rebuild them, put them back together again, understanding how they interact, to start to arrive at your solution. The reason I needled you a bit about your engineering education, is that that is where these abilities come from when you are starting out. Some of the judgement and experience will come from a senior engineer or your boss until you gain some of your own. The reason you didn't find anything about moments of inertia w.r.t. openings, in a textbook, is that they are only related to each other through the dissection and putting back together process mentioned above.
For starters, answer these questions.... How does the pane of glass act in the Al. frame? How does it load the frame? Is it pinned or fixed in the frame? Does it add any torsional loading to the frame? Is the glass itself strong enough, and for what pressures and at what sizes? What impact loading can it take, say a 2x4 projectile, at what mass and speed?
How is the sash frame or door frame supported in its structural frame in the bldg.? Are these four sash or door frame pieces separate beams, and then do they also act as a unitized frame for the whole door? What loads does the glass pain impart on these Al. frame members, and what are their stresses and deflections? How do your CAD moments of inertia fit into this picture?
You have to answer these types of questions for every different size of sash or door, for each different pressure level; each variable that can change must literally be iterated through its whole range of values, sizes or lengths, etc. Once you understand the fundamental of the subject and your specific problem, and really understand the calcs. involved, really well, you can write an Excel program to help you with this calc. process. At the same time, you test a couple of your std. units at different pressures, different support options (two hinges or three, etc.), different sizes, etc. Then you compare these test results to your calc'ed. results, and mostly you adjust your calc. approach to match the test results, because you pretty much can't argue with a well thought out test result, but you may have made some erroneous assumptions in your first go round at your calc. approach. Pretty soon you become a valuable drafter, tech. or engineer, with some real judgement and experience, but the computer or a few programs won't do this for you. You must learn it and earn it.

26 Jan 12 17:20I don't think a door really does that well with beam theory. I would liken it to a plate, possibly with a rectangular hole for a window, and solve using plate theory. Looks reasonable for FEA.
As far as analysis, if it is really that important, then buy a door and test in the lab. Should be fairly easy to uniformly load to achieve the required pressures. Not sure which is cheaper: to test or to model.
