process of steel grating
Steel bar grating is the most popular of all grating types due to its strength, cost-efficient production and easy installation,
Universally used in most general industrial plants as well as commercial buildings,
It has wide applications as walkways, platforms, safety barriers, drainage covers and ventilation grates.
Standard welded steel bar grating is also ideal for use as mezzanine decking since it supports the same loads as comparable solid flooring, more than that
