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 grating with firm welding,smooth surface and high strength.

Normally,Hot galvanizing will be carried out after end welding process,For the thickness of bearing bars is not less than 5mm,the weight of average Zinc Layer will not be less than 610g/m2.When the thickness of bearing bars is less than 5mm,the weight of average Zinc Layer
Will not be less than 460g/m2. The quality and requirements after hot galvanizing are subject to the standards of GB/T 13912.
Plain steel bar grating usages:
Widely used in petroleum chemical industry, power plant, water and sewage treatment plants, municipal engineering, environmental sanitation engineering fields of the platform, footpath, zhanqiao pier, ditch lid, manhole cover, ladders, fences, guardrail etc.
