Heavy-Duty Steel Grating
Heavy-Duty Welded Grating has the strength for heavy-duty load areas
such as airfields, highways, industrial plants, truck and bus terminals,
parking lots and railroad yards. Common uses are flooring, driveways,
subway and tunnel ventilation grilles, curb inlet grates, ramps, docks, etc.
Standard heavy-duty bar grating is resistance-welded for durability,
strength and safety using an automated electric/hydraulic welding
process. High temperatures, combined with high pressure, fuse the
bearing bars and cross bars together to form a permanent joint.
It is a sturdy grating to carry loads and maintain the same level over
many years of use. Whenever rolling wheel loads are to be used over the
grating, we recommend that the grating be load banded to add lateral
strength. Serrations are available on bars up to 3/8" thick to provide
additional traction for rolling loads.
Also, AMICO-Klemp® is one of the few manufacturers that has the
capability of providing you with those “really big” grates. Our heavy-duty
fabrication department regularly custom fabricates grating to meet specific project requirements. Virtually any bar size and depth can be made
to order.

U = safe uniform load, psf (page 92)
C = safe concentrated load, pfw (page 92)

F = fiber stress, 20,000 psi
Material: ASTM A-36
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.
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.
For deflections of uniform and concentrated loads, consult AMICO-Klemp®’s
engineering departments.

Cross Rods 4" C/C
U = safe uniform load, psf (page 92)
C = safe concentrated load, pfw (page 92)
D = deflection, inches
E = modulus of elasticity, 29,000,000 psi
F = fiber stress, 20,000 psi
Material: ASTM A-36
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.
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.
For deflections of uniform and concentrated loads, consult AMICO-Klemp®’s
engineering departments.

Steel Bar Grating Heavy-Duty
HEAVY-DUTY WELDED (H) 1-3/8" C/C Bearing Bars
22-H-4

Cross Rods 4" C/C
U = safe uniform load, psf (page 92)
C = safe concentrated load, pfw (page 92)
D = deflection, inches
E = modulus of elasticity, 29,000,000 psi
F = fiber stress, 20,000 psi
Material: ASTM A-36
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.
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.
For deflections of uniform and concentrated loads, consult AMICO-Klemp®’s
engineering departments.

Cross Rods 4" C/C
U = safe uniform load, psf (page 92)
C = safe concentrated load, pfw (page 92)
D = deflection, inches
E = modulus of elasticity, 29,000,000 psi
F = fiber stress, 20,000 psi
Material: ASTM A-36
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.
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.
For deflections of uniform and concentrated loads, consult AMICO-Klemp®’s
engineering departments.

Steel Bar Grating Heavy-Duty
HEAVY-DUTY WELDED (H) 2-3/8" C/C Bearing Bars
38-H-4
38-H-2
Cross Rods 4" C/C
U = safe uniform load, psf (page 92)
C = safe concentrated load, pfw (page 92)
D = deflection, inches
E = modulus of elasticity, 29,000,000 psi
F = fiber stress, 20,000 psi
Material: ASTM A-36
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.
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.
For deflections of uniform and concentrated loads, consult AMICO-Klemp®’s
engineering departments.
