STEEL GRATING: We have many kinds of grating ; we can produce and design gratings according to customer different environment , bearing capacity, span, shape, colour and cost .
High intensile strength : firm mesh pressing welding structure make it high load bearing;
Light structure : easy to lift
Beautiful shape ,durable : hot galvanization treatment make it good corrosion resistance ,
smooth surface
Ventilation, lighting, cooling, explosion-proof, non-slip performance;
Standard type: 1m×6m(special sizes are available)
Material: Carbon Steel
Surface Treatment: Galvanized,Hot-dipped Galvanized or black.
Appearance of Surface:Plain or Serrated.
Steel grating usage : steel grating is also named grill plate ,widely used in petrochemical, power plants, water, sewage treatment plants, public works, sanitation projects such as the platform, walkway, bridge, building groove, covers, ladders, fences, guard rails and so on.
