selecting a bar grating product, consider Welded Steel Grating first. Usually our
most economical products, they provide a comfortable walking surface with nearly 80
percent open area. This, combined with the positive welded cross bar/bearing bar
intersection, make these products our most popular. Manufactured from ASTM A-569
carbon-steel, welded gratings are recommended for nearly all industrial flooring
applications. |
|
| To specify welded steel grating, first specify the type of grating from the table below. In the instance of standard welded grating, the "W" indicates the assembly of the grating shall be Welded construction, the "19" indicates that the bearing bars shall be 19/16's (1-3/16) inches on center, and the "4" indicates that the cross bars shall be spaced at 4 inches on center. Following selection of the type of grating, consult the load table to select the appropriate bearing bar size for the loads and spans to be serviced. Proper designation for standard welded grating with 1" x 3/16" bearing bars is indicated W-19-4 1" x 3/16". | |

STANDARD |
|
Standard Welded Grating with bearing bars spaced at 1-3/16" on center and cross bars at 4" on center. The workhorse of industrial flooring products serving a multitude of applications. | ||||
| OTHER BAR SPACINGS AVAILABLE |
|
Bearing bars spaced at 1-3/16" on center and close spaced cross bars at 2" on center. Preferred for short spans and where small wheeled carts must smoothly pass over the grating. | ||||
|
Bearing bars spaced at 15/16" on center with cross bars at 4" on center. Provides additional floor surface area and increases load capacity by 26% when compared to standard spaced products. | |||||
|
Bearing bars spaced at 15/16 on center and close spaced cross bars at 2" on center. Yields the dual advantage of closer spaced bearing bars and cross bars. | |||||
|
|
The bar spacings on types W-11-4 and W-11-2 both conform with the rigid provisions of the Americans with Disabilities Act. When specifying gratings to comply with ADA requirements, it is critical to specify that the bearing bars span "perpendicular to the normal flow of traffic." | ||||
