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. |

|
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
engineers
approval. |
D
= deflection, inches |
|
E
= modulus of elasticity, 29,000,000 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. |
