STANDARD WELDED STEEL BAR GRATING

15W4 & 15W2 15/16" 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.
Standard panels are available in widths of 2', 3' or 4'.

Welded steel bar grating is resistance welded to create a
rugged, one-piece constructed panel. The bearing bars
are automatically resistance welded at the contact point
with the cross bars and, under a combination of high heat
and pressure, are fused together to form a permanent
joint. The cross bars provide a high degree of rigidity,
yet retain a smooth flat surface for free and easy walking.

Cut to size panels, please contact us.
Click on desired panel size: 2' x 20', 3' x 20', 3' x 24'

U = safe uniform load, psf Material: ASTM A-569 standard
C = safe concentrated load, pfw Deflection: Spans and loads to the right of the bold line exceed 1/4"
deflection for uniform load of 100 psf which provides safe pedestrian
comfort. These can be exceeded for other types of loads with engineer’s
approval.
D = deflection, inches
E = modulus of elasticity, 29,000,00 psi
F = fiber stress, 18,000 psi
Serrated Bars: For serrated grating, the depth of grating required for a
specified load is 1/4" deeper than that shown in the table.
General: Loads and deflections are theoretical and based on static loading.
