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.

1. What is the application of steel grating?
The main usage can be divided to 4 kinds: platform, flooring, stair treads and drainage cover.
See the above pic for reference.
2. what is the quantity of galvanization? And how long will it last?
We do our galvanization as American standard, for over 5mm thick steel grating, it is no less than
610g per square meter , for less than 5 mm thick steel grating, it is no less than 460g per square meter usually it is 60-80μ per square meter. And it can last at least 50 years.
3. Which standard can your products meet?
We can produce as customer's need. Here are most popular standard:
4. Do you provide design?
