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)
