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.
Step Ladder:
In addition to producing stair tread, we also can make the stair tread into steel ladder. In order to reduce the workload of the construction site, reduce the cost. Our steel ladder can be whole hot dip galvanized after finished, avoid the later welding construction destroy the galvanized layer. Please refer to the specifications of the selection of steel ladder atlas, also can inform our the height of the required, slope, we also can according to your special needs to processing customized specific steel ladder.
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. |

6. The HDG surface provide strong antirust capacity with service life upto 30 years without any maintenance.
7. High drainage rate.
Tolerance of Galvanized steel grating :
The allowed deviation of length is +0/-5mm, while the allowed deviation of width is +/-5 mm. The non-perpendicularity of bearing bar is allowed no more than 10% of width of bearing bar. Cross bar surface should not surpass bearing bar surface 1mm, beginning & end of cross bar should not surpass the end surfaces of two sides of grating 2mm.
