Steel grating is used for many different applications and is part of our range of safe and sustainable access products. Grated access flooring can be made from other materials, such as GRP and aluminium, but steel remains the industry leading material choice, primarily due to its sustainability, durability, and versatility.
We&#;ll explore in detail our most popular steel grating products, Safegrid and Safegrid Treads, their uses, and how they can improve safety and accessibility for your project. This guide explains everything you need to know about steel grating products so you can decide which is the right one for your project requirements.
Steel flooring for working walkways and platforms must comply with the British Standards (BS) for ball proofing. These regulations are mandatory for all overhead steel flooring in the EU and the UK. The standards state that: &#;Floorings of working platforms or walkways shall only have such maximum openings that a ball with a diameter of 35mm cannot fall through. Floorings above a place where people are working, as opposed to the occasional passage, shall have such maximum openings that a ball with a diameter of 20mm cannot fall through.&#;
Depending on where the steel grating is being installed, including the height of the grating, whether it will be walked on, and more, all determine the the ball proof requirements it must meet in order to be compliant. The smaller the pitch of the flooring (the gaps between the bars in the steel grating), the less risk there is of objects falling through and causing injury to anyone passing underneath.
20mm (20BP) &#; used for overhead walkways when the risk of falling objects is high. This size is also required for all grating used as fire escape stairs.
35mm (35BP) &#; more suitable for walkways where people occasionally pass underneath.
Utility Grating &#; for below-head or ground-level walkways where nobody can pass underneath. The risk of falling objects is negligible.
Our Safegrid products offer the most efficient and sustainable steel grating access solution on the market; Utility grating is produced using the least amount of steel of any comparable product where ball proofing is not required. We have been manufacturing products in our Safegrid range for over 100 years, and they are the established industry standard for UK manufactured, high quality steel grate flooring. In fact, in many industries &#; the oil & gas industry in particular &#; our grating is synonymous; known simply as &#;Kennedy grating&#;.
Sustainable
Compliant
High performance-to-weight ratio
Recyclable
Safegrid offers strength and durability with its high performance-to-weight ratio. Its grated structure makes it exceptionally good at bearing heavy loads with maximum safety. It spreads the weight evenly across the entire grating span, utilising its multiple reinforced points. The steel grids we manufacture here at Lionweld are built to last using quality materials. Our Safegrid products are also corrosion-resistant, making them less susceptible to damage and general wear and tear over time. All of our products comply with British and European safety standards (BS-0:+A1:), ensuring the products you choose have been designed to the highest levels of safety.
We recommend 3 variants of Safegrid, each of which complies with the above ball proof sizings:
20mm ball proof Safegrid
&#; to be used where; a walkway is in constant use; traffic may pass regularly beneath; or where people work below a walkway. Compliant to BS &#; 0: + A1: (British) and BS EN ISO &#; 1: (European) Standards. 20mm ball proof flooring should also be used on fire escape stairs.
35mm ball proof Safegrid
Link to Kuojiu
&#; to be used for walkways with infrequent use, occasional traffic passing below or no people are working beneath. Compliant to BS &#; 0: + A1: (British) and BS EN ISO &#; 1: (European) Standards
Utility Safegrid Grating
&#; To be used for walkways below head height where people cannot pass underneath. This range is non-ball proof, has the widest pitch and is the most sustainable steel grating available on the market as it uses the least amount of steel.
Our Safegrid Treads products are our access products designed for stairways. They do exactly as their name implies; they provide a safe walking surface for stairs. The Safegrid Tread is manufactured with integral end plates with drilled holes so they can be bolted to stair stringers. Our drilled hole positions have been standardised across our tread range, but alternative drillings are available on request.
The nosing bar is then attached along the full width of the leading edge of the tread and this is selected to suit the requirements of your project, considering slip resistance, visibility and loading Our standard nosing options include Liongrip, Durbar and Hi-Vis.
Compliant and safe
Available with three different standard nosing options
Available in 35mm or 20mm ball proof configuration
Able to be bolted to stair stringers
If you want a safe and compliant access solution that can consider have specific slip resistance, visibility, and loading capacity requirements then our Safegrid Treads products are the leading product. Available to comply with both 20mm and 35mm ball proofingwhich can change depending on where the stairs are located and the volume of traffic underneath. We manufacture all our Safegrid Treads to comply with the British and European standards (BS-0:+A1: and BS EN ISO &#; 1: respectively).
Made using our Safegrid steel flooring, each stair tread is built with integral end plates for bolting to stringers, alongside a nosing bar to the leading edge, our stair treads are supplied in standard widths, the flooring pitch will determine which is most suitable for a project. We are the only UK manufacturer of steel grating and steel stair treads, meaning that we have the capabilities in-house to produce custom Safegrid Treads for your project. View our Technical Data for more specifications.
These products are compliant with British Standard BS EN ISO -2: and BS-0 +A1 in relation to flooring and treads, but what does that actually mean and cover? The following covers the specific requirements of these standards for all steel grated flooring, and as such details how both Safegrid and Safegrid Treads should be used and the quality specifics they meet.
When it comes to steel grated flooring, there are strict considerations that should be factored into any design to ensure the safety of those in the area at all times.
Specifically, when it comes to walkways and platforms (the typical applications for steel grated flooring), how the space will be used needs to be taken into account, for example;
Will tools, spare parts etc be carried across it?
How quickly will people be passing across the space?
The position of the walkway or platform?
The likely load bearing requirements of the space?
How frequently and for how long will these structures be used for?
The number of operators that will be using the space and tools they will require or be using?
What (if any) obstacles may be in the space? Does this affect any of the above factors?
Where does the walkway or platform lead to, is it a deadend?
The condition of the surrounding walls (if any)
The need for any unrestricted or restricted areas on the walkway or platform
When it comes to specific measurements, the British standards access gauge for walkways sets out strict requirements for any space that requires a steel grated flooring walkway or platform. These standards are in place to ensure the safety of all involved or using the space at any time.
The minimum head height for over working platforms and walkways is mm, unless exceptional circumstances are apparent. If there are any obstacles that are unavoidable, this may drop to a minimum of mm head height and should be fitted out with the relevant padding and warning signs required to warn all who use the space of the limited head height available.
The minimum width of a walkway or platform should be no smaller than 800mm. This allows for safe passage through the area. Where a passageway or walkway is to be used by multiple operators simultaneously, this minimum width increases to mm to allow for the added usage.
If there are extenuating circumstances such as a machine, or the walkway is only in use for a small number of hours for a limited number of days within a 30 day period, then the minimum width can be reduced to just 600mm.
Further reductions can be made, if the walkway or platform is over a shorter distance of less than mm, in this case, the minimum width can be dropped again to just 500mm wide. This minimum width also applies if, at floor level, there are obstructions such as pipes or electric works. Along with the reduced minimum width, in these circumstances, the maximum height can be reduced to just 200mm.
Where the horizontal walkway is interrupted and the vertical height between two walkways or platforms cannot be closed by stairs, a single step can be installed as long as:
the step is clearly visible through colour or guard railings to alert operators to its presence
the height of the step is between 150mm and 300mm for safe usage avoiding trip hazards
When it comes to any flooring, there are strict requirements and safety measures to adhere to, to ensure all parties are safe at all times.
There are an array of instances where a hazard could occur in relation to flooring, we will cover the most common here and specify the British Standards Regulations specific instructions for each one.
British Standards stipulate that the height difference between the 2 sections of flooring joined together should be no more than 4mm, or any gap between 2 sections should be no larger than 20mm.
Both enhanced slip resistance and ribbed walkways should be installed where needed, particularly on ramps with an angle pitch of between 10 & 20 degrees. The distances between these measures should be between 400 & 500mm. The height of any ribs in the flooring should be between 10 & 20mm.
All flooring should be designed in a way that ensures liquids that accumulate for any reason are able to safely drain away, preventing further hazards or injury from occurring.
The British Standards Regulations state that where a risk assessment has identified a hazard as a result of falling objects, is more significant than other hazards such as slipping, then the flooring should be a closed top flooring to eliminate this risk.
However, for grated flooring that is manufactured with gaps, other requirements apply:
If the gaps are greater than 20mm then; either a toe plate at least 100mm in height should be installed OR the gap should be reduced
If the gaps are greater than 20mm but less than 120mm, a toe plate of at least 100mm should be fitted. Where a 100mm high toe plate is not possible due to obstructions, this can be reduced to a minimum height of 50mm
If the gap is greater than 120mm but less than 180mm, a toe plate and a handrail (or equivalent) structure with a height of between 900mm and mm should be installed.
If the gap is greater than 180mm, whole body access is possible, in which case, a guard rail should be fitted to prevent access to the gap.
Where metal treads or landings are used for fire escapes, the gratings shall not allow passage of a 20mm diameter ball.
To avoid any falls through a floor, the British Standards clearly stipulate that any removable elements of the flooring should be secured with fastenings to prevent movement and it should be possible to inspect all fixings to detect any corrosion or hazardous loosening.
All walkway and platform products are designed in accordance with British Manufacturing standards.
When looking specifically at the British Standards regulations for walkways and platforms, each of these should be designed with the load bearing requirements in mind. These regulations state that determining these requirements should take into account:
the number of operators that will be working on each specific location
the mass of any tools, spare parts and equipment needed at the location
the strength of impact on the structure due to a drop of tools or machine parts
Any possible concentration of loads due to weight distribution of parts needed at the location
Any weight due to environmental causes like water or snow, that can be deposited at the location
There are simple formulas used to calculate the load bearing weight requirements, these are:
for evenly distributed loads across a structure, it would work out as 2kn/m2
for concentrated loads applied to an unfavourable area, it would work out as 1.5kn per 200mm x 200mm space
When loaded with the design load, the deflection of the flooring shall not exceed 1/200th of the span.
When we work with a client, we take into account any deflection under the dynamic loading, any possible lateral movements of a platform, ensuring no loss of balance of the user of the platform or walkway.
Where a platform or walkway has an area of load bearing space alongside an area of non-loaded space, any height differences should not exceed 4mm.
