Steel grating is made by the world first-class 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 ring which is controlled by computer. The material of steel grating is mainly Carbon steel Q235, and the surface is hot dip galvanized, which can prevent the grating from oxidation,  also we can make it in stainless steel 304/316. The steel bar grating has the advantage of ventilation, good lighting,  anti-slip, explosion-proof, etc. we can can produce high quality gratings with firm welding,smooth surface and high strength. 

serrated bar steel grating advantages: 

Light structure

High strength

Powerful anti-corrosion, durable and long working life

Beautiful appearance, bright surface

No dirt-rain-snow deposit, automatic cleaning, easy maintenance

Good ventilation, day lighting, heat dispersing, resistant to sliding and explosion

Easy installation and disassembly

Flooring galvanized Steel grid plate is made by Carbon or mild steel of certain sizes through the processing of grooving, lock-pressure, welding, finishing and other treatment. Industrial bar gratings can be actually made from copper, aluminum and other materials, while galvanized steel grating is the mostly used one due to its economic cost and good property.

Application:

Steel grating, with robust design and spanning abilities, is very strong and safe for the support of floors and elevated walkway. It can be used for ceiling, interior decoration, decoration, platform aisle, ventilation windows, (Wells), advertising plaque and other construction.
