Vision of steel grid
HomeNews Center 〉 Development Vision of Steel Grating

The appearance of steel gratings in China was in the last century. In 1986, Australia Huafu Group invested in the establishment of a steel grating production base in the Guangzhou Development Zone of China. Since then, steel grating products have officially entered China. Steel grating products are used in many professions.

What is a steel grid ? A steel grid is a flat steel that is placed at a certain distance and crossbars, and welded into a steel product with a square grid at the base. What is the use of a steel grid? It is mainly used to make trench cover plates, composite steel grid plates, step plates for steel ladders, etc. Crossbars are usually made of twisted square steel. Steel grid plates are usually made of carbon steel, and the surface is hot-dip galvanized, which can avoid the effect of oxidation and can also be made of stainless steel. The steel grating has the functions of ventilation, lighting, heat dissipation, non-slip, explosion-proof and so on.

China's steel grid production standard selection is YB / T4001.1-2007 standard; other US, UK, Australia and New Zealand also have their own standards. Steel standards are in accordance with GB / T700-1998.

The main production methods of steel grid plates are: machine pressure welding and manual manufacturing.The machine pressure welding uses high-pressure resistance pressure welding machines.The manipulator actively places the horizontal bar on the flat steel placed uniformly.Through strong welding power and The hydraulic pressure presses the cross bar into the flat steel, and then it can obtain the high quality steel grid plate with the solidified joints, high stability and strength. The steel grid plate manufactured by the craft is first punched in the flat steel, and then the horizontal bar The rod is spot-welded in the hole.There will be open space between the crossbar and the flat steel, and it is impossible to weld at each contact point, so the welding is not strong and the strength is reduced.

In recent years, China's steel grating products have been widely used in petrochemical, municipal engineering, port engineering, machinery industry, power plants and water plants, steel industry, manufacturing, food processing industry and many other occupations.

The standard production and sale of steel grid panels in China should be said to have begun only after the establishment of Guangzhou Meiluo Steel Grating Co., Ltd. in 1987. Most of the talents in the domestic steel grid industry are directly or directly cultivated by the Huangpu Military Academy in Guangzhou Metro. The prospect of the steel grating industry is good. It should be said that steel gratings will be increasingly used in many areas.

There are three major shopping malls for steel grid panels : South China Mall based in Guangdong, Yangtze River Delta Mall in Shanghai, Wuxi, Nanjing, and Ningbo. Northern Malls in Beijing, Hebei, Tianjin, Shandong (Yantai), Dalian and other regions. The steel grid products produced by the company's self-developed CZY-II-2400-1.25 energy-saving wide steel grid plate self-controlled piezoresistance welding machine have also been applied to national key projects such as "Beijing Olympic Bird's Nest" and "Water Cube" , And exported to the United States, France, Norway, the United Arab Emirates, Malaysia, Singapore, South Korea, Brazil, Southeast Asia and other countries, the shopping mall vision is very promising.
