Welded steel bar grating is the most popular of all grating types due to its strength, cost-efficient production and easy of installation. Universally used in most general industrial plants as well as commercial buildings, it has wide applications as walkways, platforms, safety barriers, drainage covers and ventilation grates.
It is also the ideal for use as mezzanine decking since it supports the same loads as comparable solid flooring. More than that, its cost saving openness maximizes the circulation of air, light, heat, water and sound, while promoting cleanliness.

The steel grating plate is formed by crosswise arranging bearing bars and cross bars (twisted square steel, twist steel, flat steel and so on) at certain intervals, performing orthogonal combined welding or pressure locking for fixing to form a steel member with square gratings in the middle, and performing deep processing through processes of cutting, tapping, edge covering and so on and meets the requirement of customers.

The steel grating plate is mainly used for manufacturing steel structure passage platforms, step plates of steel ladders, various trench covers and so on, and is roughly classified into a pressure-welded steel grating plate manufactured by welding flat steel and cross bars through a pressure resistance welding machine, and a pressure-locked steel grating plate manufactured by transversely and longitudinally welding flat steel according to manufacturing methods. The finished steel grating plate can be prevented from being oxidized through hot galvanizing generally. The steel grating plate also can be made of stainless steel. The using amount of the steel is saved most under the same load condition, and the material of a supporting structure can be correspondingly reduced. Expense is saved, and the mounting process is simplified. Rain water, ice, snow and dust are not accumulated, and the steel grating plate is not required to be cleaned or maintained, and is widely applied to many projects in China.
