Product Description

stair treads description

Steel grating stair treads are high-strength, durable, and anti-slip stepping materials designed for industrial and construction applications. They are widely used in factories, petrochemical plants, ports, power facilities, water treatment plants, transportation projects, and public buildings for stairs, platforms, and walkways.

We offer a variety of tread types, including welded or bolted fixing, with or without checkered plate nosing. These designs provide excellent anti-slip performance while allowing for easy installation and removal. Materials can be selected from mild steel (low carbon steel) or stainless steel, with surface treatments including mill finish, painted, powder-coated, or hot-dip galvanized finishes, suitable for different environments and usage conditions.

1)There are six kinds of stair treads T1,T2,T3,T4,T5 ,T6

    T1         Welded fixing and Without nosing

    T2         Bolted fixing and without nosing,easy to installation and teardown.

    T3         Welded fixing and with checkered plate nosing, can be skid.

    T4         Bolted fxing and with checkered plate nosing, easy be installation, teardown and can be skid.      

    T5        Welded fixing with anti-slip strip, providing enhanced safety.

    T6        Bolted fixing with anti-slip strip, easy to install and dismantle, with better quality.
