Product description
Most grating platform and walkway applications require stair treads to access the various levels that are inherent in most project applications.We offer a full range of aluminum grating tread profiles to meet the various demands in marketplace.Whether the project requires a standard maintenance access tread or a closer mesh and more pedestrain friendly product,we can offer a varity of competitive and cost effective products.
Our sales team and engineering support group can helly with product specifiications regarding slip resistance surface(serrated) to meet the needs of our clients.
Fabricated aluminum stair treads are available in aluminum rectangulai bar and aluminum I-Bar.Treads can be ordered with a plain or serrated surface.
Type Available
According to whether the nosing to be used and methods of mounting to stringers,grating treads are classified into four types,expressed as AT1,AT2,AT3,and AT4.

Bearing bar centers at 20mm: This kind of fine mesh steel gratings have strong load ability and also can prevent the access of sundries of 18mm in diameter. This kind of gratings fit for pedestrian deck, walkway and ditch covers which require high security
Notes: common welding standard: single-side full welding every 6 bearing bars |
Bearing bar centers at 30mm: This kind of steel grating is the most commonly used in projects with American, Australian, Japan standards are available. This kind of gratings are featured well by heavyduty, well resistance of strong impact on surface. this kind of steel grating fit for all kind of industrial platforms.
Notes: common welding standard: single- side full welding every 5 bearing bars |

Bearing bar centers at 40mm: light grating and very economical. This kind of gratings fit for fixed platforms, walkway, and stair treads and British, German,French and Japanese standards are available. The products most commonly used for Belt corridor, storage shelf,Attic panel, trestle, guardrail, sunshade gate, etc. notes: common welding standard: single- side full welding every 4 bearing bars |
Bearing bar centers at 60mm: This kind of steel gratings are especially used for mining industries. It can solve the problem that mineral splashing down and stacks on the walkway. This product usually used for mineral miningand processing and it is the best choice for workshop, meeting room and suspended ceiling of stadium in terms of it's light weight. notes:common welding standard: single- side full welding every 3 bearing bars |
Installation of steel grating
1.Welding & using saddle clips are two ways for installation of grating. The welding is suitable for those places where there is no need to move or dismental,for instance,the flooring around the machines. However,using saddle clips are featuring in easy installation & saving zinc layer.
2.Regarding welding installation, angle wolding would used at the first bearing bar of every corner,which the welding length is no less than 20mm,&the height is no less than 3mm.
3.Saddle clip composed of a top plate,a hold down & a M8 bolt, is suitable for all kinds of steel gratings installation.
4.Regarding saddle clip installation, at laest four sets of saddle clips would be used in one pc grating.It would be better using more in the staddle for those gratings with a bigger span.
Features
1.Hot-dip galvanizing: Rust strong, maintenance-free and replacement.
2.Best drainage: water leakage area of 83.3%, is more than double the cast iron.
3.Save investment: long-span. Heavy load than cast iron and the lowest savings in the cost of replacing stolen, then crushed.
4.High strength: strength and toughness is much higher than cast iron, can be used for port, airport and other large span and heavy load conditions.
5.Size Multi: different specifications can meet the different environments, load. Span, size and shape required.
