Steel grating main kinds: plug-grating, stair stepping board, ditch cover, steel ladders, working platforms, building ceilings, etc.
Material: hot dipped galvanized steel grating, stainless steel grating.
The steel grating has the characteristics of ventilation, lighting, heat dissipation, non-slip, explosion-proof, and so on.
Mild carbon steel provides an economical, high strength for use in most industrial and commercial applications. And hot dipped
galvanized surface treatment supplies excellent corrosion resistance performance for durability.
