Flat Bar Stainless Steel Grating Serrated Bar Grating From Jiulong
Heavy duty steel grating is a steel grating product specially developed for special load-bearing occasions.
The biggest feature of heavy steel gratings is their large load carrying capacity and the strongest impact resistance.
If there is a requirement for anti-slip effect, it is recommended to use a toothed steel grating to provide better friction.
It is the first choice for some places with large loads.
