Zhenxing Steel grid stair treads as well as the Steel Grating tread. Steel Grid Stair Treads is made of steel grating & wildly used for different types of Steel Ladders, Industrial Stepping Board, Side Foot Stair Board. We fabricate dimension according the customer's requirements. Stair Tread is available in grating, plate, perforated plate and expanded metal. It`s installed in the road or flooring, where the chance of skidding are there. This Stair Tread is available with or without angle frame. It easily retrofitted over existing grating or unsafe diamond checker plate assemblies. Meantime Stair Tread can be welded directly to current treads or stringers or can be bolted in place. Holes can be provided per drilled for easy installation or can be drilled and countersunk in the field, without harming the surface. Therefore grating stair treads are ideal in wet and oily situations such as oil rigs, food processing plants and marine applications.
Steel grating is made by the world first-class Italian ORSOGRIL equipment, which can arrange the bearing bar and cross bar in longitude and latitude order to certain distance. Cross bar is pressed into the bearing bar by high tension resistance welding which is controlled by computer. So we can produce high quality gratings with firm welding, smooth surface and high strength.
The most common specification for treads is G 325/30/100
