Introducation of hot dip galvanized steel grating
Steel Grating 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.

The grating crossbar is generally made of twisted square steel, which has the following advantages.
1)Material saving:The method of material saving under the same load condition can reduce the material of supporting structure accordingly.
2)Reduce investment:Save material, labor, construction period, free of cleaning and maintenance.
3)Simple construction: clamping the pre-installed support with bolts can be done by one person.
4)Save time:The product does not need to be reworked on site, and the installation is very fast.
5)Modern style:Beautiful appearance, standard design, ventilation and light transmission, giving an overall smooth and modern feeling.
6)Light structure:Less material, light structure, easy to lift.
7)Anti-fouling: no accumulation of rain, ice, snow and dust.
8)Reduce wind resistance:Due to good ventilation, it has small resistance when encountering large wind and reduces wind damage.
9)Superior performance of grating: good ventilation, light, heat dissipation, explosion-proof and anti-slip performance.
