Stair treads are also called steel ladder treads, treads, and ladder treads. According to the installation method, they can generally be divided into two types: welding and bolting. If the steel grating treads are directly welded to the steel section and the side panels of the treads are not needed, it is relatively economical and durable but not easy to disassemble. The bolted treads need thickened side panels on both sides, and holes are drilled in the side panels, and they are directly fixed with bolts, which can be recycled and reused.

Size and shape of stair treads:

Any type of steel grating can be made into various sizes and shapes to match various styles of stairs, but from an economic point of view, we recommend that we use our recommendations as much as possible. We can provide stair treads with different anti-slip front guards, and the size can be specified as needed.

Generally speaking: Steel grating treads have four forms according to whether there is a front guard and the connection method with the ladder beam, expressed as T1, T2, T3, and T4.

Welding fixation: ST1, ST3, ST5

 

Bolt fixation: ST2, ST4, ST6

 

Tread width is usually between 0.5m and 1m.

 

Tread marking and tolerance

 

ST4--(RA325/30) ST4--tread model, RA325/30 steel grating model

 

Tread tolerance: width W±3mm, length L-3mm.

Features:

 

(1) The installation of the tread is very simple and does not require complicated installation;

 

(2) Good ventilation, lighting, heat dissipation, explosion-proof and anti-slip performance;

 

(3) The tread is high-strength, light structure and durable;

 

(4) Maintenance is very simple and prevents dirt accumulation.

 

Use of stair treads: It is widely used in platforms and walkways in factories such as power plants and water plants, and in the fields of municipal engineering and sanitation engineering, as well as ground platforms in large places such as theaters, viewing platforms and parking lots.
