STANDARD WELDED STEEL BAR GRATING

In 19W4 & 19W2, 1 3/16" CENTER TO CENTER OF BEARING BARS

Welded Steel Bar Grating is the most popular of all grating types due to its strength, cost-efficient production and ease of 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.

It is also ideal for use as mezzanine decking since it supports the same loads as comparable solid flooring. More than that, its cost saving openness maximizes the circulation of air, light, heat, water and sound, while promoting cleanliness. And, where insurance codes permit, additional sprinklers can often be eliminated.
