Steel Grating

Quangang steel grating is manufactured by the world-class crimping machine which is controlled by computer. Plate-shaped steel grating with robust welding spots and rectangular orifices on the surface is made by pressing twisted square steel disposed in latitude and longitude directions (with certain space) into the side flat steel. The flat steel bears load and cross bar (lay-up direction) functions as connection.
Quangang steel grating is widely used in hundreds of various factories both at home and abroad, such as power plant, chemical plant, refinery, iron and steel plant, engineering works, paper mill, cement factory, pharmaceutical factory, food processing plant, etc. 
It can be used as gangway ladder, channel, pump room, platform of engine compartment of various vessels; as floor plate of various bridges, such as byroad of railway bridge, overpass, etc.; as platform of oil production plant, car washing station and high-level tower; as fence, walkway grating, pumping shaft cover and drainage ditch cover of municipal engineering, such as parking tower, large-scale sites and buildings.
