The stair tread board is made of steel grating (steel grating is a type of steel product made by intersecting flat steel with horizontal bars at a certain distance and welded into a square grid in the middle). The surface of this product is generally treated with hot-dip galvanizing or electroplating galvanizing.
Stair treads are used for
Industrial platforms, stair treads, handrails, channel floors, railway bridge side roads, high-altitude tower platforms, drainage ditch covers, manhole covers, road barriers, three-dimensional parking lots, fences for government offices, schools, factories, enterprises, sports fields, garden villas, as well as external windows for residential buildings, balcony guardrails, guardrails for highways, railways, etc.
Types of stair treads
1. According to the installation of ladder treads, they are divided into welded fixed ladder treads and bolted fixed ladder treads. The ladder treads fixed by welding are steel grating plates, while the ladder treads fixed by bolts require adding 65X5mm flat steel as side plates to the steel grating plates.
2. According to the anti slip requirements of ladder treads, they can be divided into two types: ladder treads with front protective plates (patterned plates or steel bars) and ladder treads without front protective plates. T325/30/100 (applicable for ladder tread width greater than 215mm but not greater than 305mm) T255/30/100 (applicable for ladder tread width greater than 215mm but not greater than 305mm)
 
 
Stair structure stair treads are a type of steel grating used for platform stairs. Depending on the installation method, there are generally two types: welded and screw fixed. The side panels that are directly welded to the keel do not require step boards. They are currently more economical and durable, but do not require disassembly. The step board fixed with bolts requires thickened side plates on both sides, with holes drilled on the side plates. The installation is directly fixed with bolts and can be recycled and reused. Customers can customize according to their actual needs, and any type of steel grating can be manufactured into various sizes to match the corresponding stairs. However, from an economic perspective, we recommend using the sizes we recommend as much as possible.
