Description:
Stair treads in each of these metal grating types come in both plain and serrated styles. Our serrated stair treads, also known as safety treads, are specifically designed to offer good protection against slips in areas prone to oil or other hazardous elements. Therefore, metal safety treads are perfect for industrial facilities or outdoor sites where slippery conditions may exist from time to time.
We manufacture different styles of stair ladders that used in family,industry and construction.
Material: mill steel black and hot dip Galvanizing / and stainless grating
Usage: ladder, flooring walkway, platform ,steel structures, stair tread, well cover, trench cover, sump cover,compound gratings, storage shelves,fences and handrail so on for construction project, oil project, seaport, power plant, water plant, defense project, chemical factory and so on.
Stair treads is a kind of useage of steel grating, usually we have two methods to fasten the stair treads: by welding or clamps. Thus according to different fixing methods, the stair treads is classified to 6 types. (See the pic below for reference)And among them, T1 and T4 are most popular one.
| Type | Structural characteristics |
| T1 | Used for welding installation, the end plates of both ends use the same flat steel as load flat steel to make edge band without nosing. |
| T2 | Used for bolt installation, the end plates of both ends use 65*5 flat steel to encircle the edge, and open hole without, nosing . |
| T3 | Used for welding installation, the end plates of both ends use the same flat steel as load flat steel to encircle the edge, with nosing. |
| T4 | Used for bolt installation, the end plates of both ends use 65*5 flat steel to encircle the ends ,and open bole with nosing. |
