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.
