2017 hot selling China manufacturer hot dipped galvanized 25*5 steel grating door mat
Galvanized Steel Grating is made by Carbon or mild steel of certain sizes through the processing of grooving, cutting, press-welding, and galvalizing. Gratings can be actually made from copper, aluminum and other materials. However, galvanized steel grating is the widely used for its economical cost and excellent propetries
Advantages of the Steel Bar Grating
Allows the passage of light
Allows air circulation
Prevents blockages or accumulation of trash, dust or liquid
Provides lightness and high load resistance
Due to the increasing friction that provides to the shoe sole, increases safety in working areas

Process:Our Steel Bar Grating is manufactured through the forged welding process, which consists in welding steel cross rods to perpendicular and equidistant bearing bars. This is achieved through high current and high mechanical pressure discharges, fusing the molecular elements of both components without placing filler material, as it occurs in the arc welding process. The forged welding process guarantees an homogeneous product of high quality and resistance.
We manufacture our Steel Bar Grating based on the most strict quality standards.
