Coil coating is one of the most advanced, efficient and environmentally friendly means of coating metal. Using prepainted metal can provide manufacturers with a streamlined manufacturing process, cost savings and a more environmentally friendly plant.
Hunter Special Steel Co., Ltd supply professional and honest service.
In the old days of traditional manufacturing, steel and other metals arrived at factories in a raw, untreated, unpainted state. Companies would fabricate and paint or treat the metal components of their product at the plant. This was a costly, time-consuming and environmentally harmful practice. The coil coating process was pioneered in the s for painting, coating and pretreating large coils of metals before they ever arrived at a manufacturing facility. The Venetian blind industry was the first to discover the benefits of prepainted metal.
Today, more than 800 million tons of coil coated steel and aluminum are produced and shipped in North America alone each year. Industry leaders using coil coated metal include GE, Whirlpool, Trane, Mercedes Benz, Nordyne and Steelcase, to name just a few. Thousands of products in dozens of different industries are made more efficiently with prepainted metal.
Major industries include building products such as metal roofs, wall panels and garage doors; office furniture (desks, cubical divider panels, file cabinets and modular cabinets); home appliances (refrigerators, dishwashers, freezers, range hoods and microwave ovens); heating and air-conditioning outer panels and ductwork; commercial appliances; vending machines; foodservice equipment and cooking tins; beverage cans; automotive panels and parts (fuel tanks, body panels and bumpers); and other components. New applications make the switch every year.
Coil coating is one of the most advanced, efficient and environmentally friendly means of coating metal. Large coils of metal (including cold-rolled steel, hot dip galvanized, electro galvanized, zinc-steel, aluminum, stainless steel, copper and brass) can be coated in a continuous, highly automated process prior to fabrication. During this continuous process, the metal is unwound and then cleaned and chemically treated. Depending on the product specifications, one or both sides may then be primed and/or topcoated, oven cured, and rewound for shipment.
The variety of coatings available is almost unlimited and includes polyesters, polyurethanes, epoxies, vinyls, plastisols, acrylics, waterborne emulsions, zinc-rich coatings, fluorocarbons, dry lubricants, and treatment and primer combinations. Moreover, product quality is continually improving as a result of new industry-specific coatings that are regularly coming to market and advanced testing performed throughout the coil coating process.
The prepainting process is designed to produce highly uniform, impeccable-quality coatings. The coatings are precisely applied with special equipment that provides a high-quality finish. The coatings can be on both sides of the metal and meet the finished product specifications. Manufacturers using prefinished metals will find consistent color, texture, thickness and performance in their finished products.
To ensure the best possible results, numerous quality control tests are performed during the coil coating process. For example, before coating, the metal substrate and the viscosity, color, gloss and physical performance of the paints are tested. As the uncoiled metal is coated, the surface treatment process is tested and adjusted continuously to ensure a high-quality finish. In addition, the paint thickness, curing temperature and production line speed are controlled and measured. Coating performance, including features like gloss, color, hardness, adhesion, and resistance to cracking and marring, are inspected as the coated parts leave the production line. After production, parts are tested for corrosion resistance with salt, chemical sprays and/or water immersion. Additionally, they&#;re examined for heat resistance, accelerated ultraviolet and environmental exposure. Other tests conducted on coil coated parts include stain-resistance, welding capability, and resistance to abrasion.
Prepainted parts can outperform post-painted applications because prepainted metal coils are uniformly cleaned, pretreated and painted as a flat surface. The primer coat also prevents the undercutting of paint and enhances corrosion resistance, the durability of the product and overall quality. Furthermore, the coatings are tightly bonded to the metal and often are applied to both sides of the metal.
Moreover, there is almost an unlimited selection of available prepaint coatings. These coatings are available in various degrees of gloss, color, textures, lubricity, flexibility and combinations thereof. Various primers can be selected to help create an industry-specific coating system that maximizes the performance of the product for special end-use applications.
For a manufacturer using painted steel, aluminum or other metals in the manufacturing process, the process of coil coating can dramatically improve productivity, reduce processing costs, improve quality, and reduce inventory and environmental/emission concerns, all at the same time. Just ask Trane, Inc., a manufacturer of commercial air handlers. Quality has always been a top priority for the company, and this led to the switch from post-painted metal to coil coating technology.
Several products at the Trane facility in Cullen, LA, are currently being produced using a new prepainted FAS-NER from AKH Inc., with prepainted metal. The fastener system is a simple punch and die operation, which automatically feeds, punches, inserts and locks a self-piercing fastener to produce a solid joint in one high-cycle operation. The fastener is inserted directly into prepainted metal without the need for pre-punched holes. This feature saves time and labor costs associated with tooling maintenance.
In the past, the Trane air handlers were spot-welded and then post-painted. Now, the products are completely assembled with prepainted metal. Since converting, Trane has seen an increase in productivity and profitability. Trane reports they have also experienced more consistency in the strength of the joint, as well as a better product appearance.
Several major appliance manufacturers also have experienced the benefits of using the combination of the AKH FAS-NER and prepainted metal. The fastener color is matched to the color of the finished product, allowing for the elimination of post-paint operations.
The benefits of prepainted metal are many. It can be used for most product applications and will provide manufacturers with a streamlined manufacturing process, cost savings and a more environmentally friendly plant.
**************
Although the prepainted metal process has been around for years, a few misconceptions about the process still exist.
Like most manufacturers, companies are often burdened with adapting their paint shop to changing environmental standards, strict health regulations and increasing overhead. Businesses are trying to lower costs and remain competitive. Outsourcing the metal treatment and coating operations can alleviate or even eliminate these costs.
One recommendation is to establish a prepaint conversion team, consisting of internal and external managers and suppliers, to analyze the products and process to determine if prepaint conversion is practical. This team can also act as a steering committee once implementation begins.
After the initial analysis determines that the use of prepaint is practical, a cost justification study should be conducted to determine the full economic impact of the proposed conversion. This analysis should answer three major questions:
Once the conversion process is complete, the plant will run more efficiently, more effectively and more economically. Switching to prepainted metal can improve your product and your bottom line.
Coil coated metal can be formed without any loss in surface quality or appearance. In fact, the paint system can be designed to have greater flexibility than the metal and can be shaped with a finish that is actually superior to post-paint. This is because post-painted surfaces often suffer from dirt and oil residue, uneven application, and other imperfections. After the metal has been precleaned, preprimed, pretreated and prepainted, it can be formed. The paint layer is often more flexible than the underlying metal substrate.
Some manufacturers are concerned with exposed cut-edge on prepainted metal, but research has shown that prepainted cut-edge actually holds up better over time than post-painted surfaces. The National Coil Coating Association (NCCA), with the help of PPG Industries, Inc. and the North American Zinc-Aluminum Coaters Association (NamZAC), compared the corrosion resistance of prepainted cut-edge with three types of post-paint.
Prepainted metal louvers with exposed cut edges were tested in the field alongside three sets of metal louvers, one with a post-painted electrocoat, a second with a powder finish and a third with a spray finish. The parts were made of hot dipped galvanized steel, and the louvers were exposed to the same environment over time in Daytona Beach, FL. After 16 months, 44 months and 68 months of exposure to the elements, comparisons showed that the corrosion resistance of the prepainted parts was repeatedly and significantly better than the post-painted parts.
The reason the prepainted parts outperformed post-painted ones is that prepainted metal sheet is uniformly cleaned, pretreated and painted as a flat surface, so the edge-to-edge and side-to-side variability is virtually eliminated. In addition, the prepainted part has two coats (primer and topcoat), and each is tightly bonded to the metal as compared to a post-painted part, which generally has only one coat of paint. In most cases, the prepainted part has paint (one or two coats) on the backside; in comparison, post-painted parts at best have a minimal amount of overspray. Uniform pretreatment and paint on the backside of a part increases the corrosion resistance of the part, enhancing long-term durability.
More and more manufacturers are realizing that precoated metal can be joined easily - using adhesives, a variety of mechanical assemblies with or without fasteners, or even welding - and still retain a more beautiful and flawless surface than post-painted metal.
Using adhesives as a joining method offers a variety of benefits such as smooth surfaces, clean contours and uniform stress distribution. Adhesives also seal joints away from the elements. Mechanical assembly works well with prepainted metals, both with and without fasteners. Nuts, bolts and screws are cost-effective fasteners that offer design flexibility and allow for parts to be disassembled. Using rivets offers excellent shear and tensile strength as a fastener. Prepainted metals can also be assembled without fasteners by using a variety of methods, including lock and seam, pierce and tab, or stake and clinching methods. Welding is also an option for joining prepainted metals. Working closely with a coil coater can make welding an attractive joining option.

5. Myth: You can&#;t handle coil-coated metal without marring the surface.
Fact: Precoated metal can be shipped on flatbed trucks, moved using forklifts, stored as coils for long periods - and still retain a more beautiful and flawless surface than post-painted metal. Prepainted metal can be handled successfully without harming the surface.

**************
Converting from in-house post-painted metal to outsourced prepainted metal can save manufacturers money and time, and can ensure that products are the highest possible quality. The most important issues to consider when converting to a prepaint operation are timing, capital outlay, manufacturing costs and environmental compliance. Following are 10 indicators that a manufacturer should consider using prepainted steel or aluminum:
1. In-house paint shop expenses are on the rise. When maintenance budgets are growing and capital investments are required to comply with strict EPA regulations, prepainted metal and aluminum is often a cost-effective alternative to in-house paint lines. Many hidden costs are associated with in-house spray or powder operations. Staffing with trained personnel, equipment, supplies and even environmental compliance all contribute to the expenses of owning an in-house paint shop.
2. Internal operating costs need to be lower. Many manufacturers are searching for ways to lower operating costs in order to remain competitive. Through outsourcing prepainted metals, factories can eliminate costly in-house paint operations and the associated expenses of manning the production line. Some of the major cost savings of prepaint conversion include inventory, environment, insurance, cleaning and waste removal, purchasing raw materials, and operating costs.
3. Plant capacity must be increased. By purchasing prepainted metal, plants are actually outsourcing the painting process and can eliminate or greatly reduce the size of in-house paint shops, generating more floor space for other uses.
4. Coating quality needs improvement. Coil coated metals are uniformly cleaned, pretreated, painted and cured as a flat surface, so that the edge-to-edge and side-to-side variability is virtually eliminated. The prepainted part has two coats of paint (unlike powder coating, which has only one) that are bonded tightly to the metal.
5. Downsizing and/or combining plants is taking place. A good time to consider using coil coated metals is when other major manufacturing changes are taking place. Manufacturers can reduce expenses significantly and increase paint quality greatly by outsourcing the painting process. Coil coated metals can be effectively handled, cut with superior corrosion resistance, joined with welding and adhesives, and formed for many uses&#;all with a beautiful finish.
6. New product models are being considered. Many times when design changes are being made, a prepainted metal can be specified and the new design can be more cost-effective to produce.
7. Manufacturing bottlenecks are reducing productivity. Many delays in a plant are caused by paint issues such as stoppage while parts are painted, dried and cured before moving to the next phase of assembly. These bottlenecks can be eliminated with prepainted metal. Prepainted steel and aluminum are uncoiled, cleaned, primed and painted to a manufacturer&#;s specifications and re-coiled prior to shipping to the factory.
8. It&#;s time to update or replace the paint line. Capital expenditures can be avoided and long-term cost savings achieved by choosing prepainted steel and aluminum, rather than refurbishing or replacing a paint line.
9. A strategy of outsourcing is being implemented. Purchasing prepainted metals is a cost-effective outsourcing option that actually improves the durability of the coating.
10. New fabricating or material handling equipment is being evaluated. When significant changes are made at the plant, it creates an opportunity to improve many aspects of the manufacturing process, including the use of prepainted metal.

How to Decide PPGI/PPGL Coil?
1. Coating Types
When choosing a primer, you need to consider the adhesion of the primer; while for top coating, corrosion resistance and color retention will be more important.
There are four commonly used coatings, including polyester (PE), silicone modified polyester (SMP), high durability polyester (HDP), and polyvinylidene fluoride (PVDF). PE coating is of good adhesion and it is widely used as a primer.
While HDP and PVDF because of their excellent durability and color retention.
They have the best long life span: more than 25 years.
2. Thickness of Coating
At LIYING Steel, the painting thickness is usually 18-22um. The max top paint can be 55um. Generally, the thick the coating, the better the durability.
You can choose according to the use environment. For example, I need this material: Dx51d+AZ150 PVDF/HDP 30um, it may used in the sea,or chemiercal factory. If you have special requirements, please let us know.
3.The base metal steel
The base metal steel commonly used consist of: Galvanized steel, Galvalume steel and Al-Zn-Mg steel.Generally, The more zinc content, the longer the service life.and the zinc coating ranges from AZ30g-AZ275g.

Below let's review how to choose prepainted steel for different uses.
Color coated steel is often used as roofing or wall panel for residential buildings, including civil residences, villas, guard boxes, interior decorations, army barracks, and other fields. These buildings are mainly in the living area. When selecting color coated steel, it should be beautiful, natural, interesting, and personalized. That's why custom pattern printed steel, such as wood grain, brick grain, marble grain, etc., has been more and more applied to interior and exterior decoration of civil buildings.
The prefab house is mainly used in construction sites as temporary offices, dormitories, and storage rooms. When choosing color coated sheets, practicality and cost will be more important while ensuring safety. As a temporary building, it is recommended to use ordinary color coated steel, with a galvanized sheet as substrate (common zinc layer thickness). Using PE coating as top paint, with a thickness of 15-20μm, will be a cost-effective option.
The use environment of general industrial plants and warehouses is not corrosive. When choosing
color coated steel
, it requires more practicability and cost-effectiveness, rather than higher corrosion resistance and aging resistance. Therefore, PE color coated steel is the most widely used in general industrial plants and warehouses. It adopts galvanized sheet as substrate with a double-sided zinc layer of 80 GSM, and the top paint thickness is 20μm. Of course, you can also lower or improve the quality requirements of the pre-painted steel according to your budgets and specific industries.
Unlike general industrial plants, chemical plants, chemical tanks, and other chemical projects are highly corrosive. Chemical products are prone to produce highly corrosive volatile substances, such as acid or alkali. It is easy to form acid or alkaline dewdrops on the surface of the color plate when exposed to water. Then the acid or alkaline dewdrops will corrode the painting, and further corrode the zinc layer and even the base metal. It is recommended to use PVDF or HDP coated steel sheets, and the ideal thickness of the top painting is 20-25 μm, with Z275
galvanized sheet
or AZ150 galvalume sheet as substrate.
Non-ferrous metal smelting factories, steel mills, power plants, etc., are also highly corrosive. Because coal combustion produces a large amount of corrosive media, such as sulfur dioxide ,which is easy to corrode steel plates. So the color coated steel used in these industries requires high corrosion resistance. It is generally recommended to use PVDF or HDP coated color steel. Besides, the zinc layer on double sides of the substrate is no less than 120 GSM, and the paint thickness (top/back) is no less than 25 μm/15 μm.
Static is dangerous in industries such as clothing, textiles, electronics, instruments, medical facilities, etc., which may lead to safety accidents. Therefore, the color coated steel used in these workshops should be anti-static. The painting of antistatic color steel is with special conductive pigments. The anti-static steel is able to prevent dust from adhering and it is easy to clean. In terms of substrate, it is recommended to use galvanized steel with a zinc layer not less than 80 GSM, and the top coating thickness is not less than 20 μm.
Arched roofing sheets are mainly used in stadiums, trading markets, exhibition halls, warehousing, and other fields. Due to the arched roofing with no beams, and no purlins, but a large space span, it requires high-strength color coated panels. According to the span of the arch roof, it is recommended to use a base metal with a yield strength of 280-550 Mpa. The recommended code includes S280GD+Z - S550GD+Z. And the zinc layer thickness is not less than 120 GSM. The coating structure is generally double-coating and double-baking. The face painting thickness is not less than 20 μm. While the painting can be PVDF or HDP or PE according to your budget and the use environment.
