[[MetaDescription]]
Welded steel grating is our most economical and durable product, “W” type welded steel gratings are manufactured by forge welding rectangular bearing bars and drawn cross bars. This welding process provides a reliable welded connection that will last for years in the harshest conditions. Spacing 19W4 welded steel grating is our most popular product and is recommended for most industrial flooring applications.
The installation and construction process of the welded steel bar grating is very simple, only one person can complete it, and the time-consuming is also very short. The surface is non-slip and corrosion-resistant, so it is widely used as walkways, stairs, fences, shelves, ceilings, and floors. It has good drainage function, high strength, and strong bearing capacity, so it is often used in bridges and overpasses. The welded bar grating is light in weight, so it is more convenient and fast to transport, as to save manpower and time.

Spacing Tables of Welded Steel Grating
19-W-4 Open Area: 78% |  | Bearing bars spaced at 1-3/16" on center and cross bars at 4" on center. The workhorse of industrial flooring, popular for platforms, catwalks, mezzanines, and stairways. |
19-W-2 Open Area: 73% |  | Bearing bars spaced at 1-3/16" on center and cross bars at 2" on center. Excellent for short spans and applications where small wheeled carts continuously cross the grating surface. |
| 15-W-4 Open Area: 75% |  | Bearing bars spaced at 15/16" on center and cross bars at 4" on center. The closer spaced bearing bars increase load capacity by more than 26% when compared to similar gratings produced with bearing bars a 1-3/16" on center. |
| 15-W-2 Open Area: 69% |  | Bearing bars spaced at 15/16" on center and close spaced cross bars at 2" on center. The closer spaced bearing bars and cross bars provide additional flooring surface to support pedestrian and wheeled traffic. |
11-W-2 Open Area: 63%11-W-4 Open Area: 68% |  | Bearing bars spaced at 11/16" on center and cross bars at either 4" or 2" on center. Types 11-4 and 11-2 with 3/16" thick bearing bars comply with the spacing requirements of the Americans with Disabilities Act. For ADA installations, specify that the bearing bars span perpendicular to the normal flow of traffic. |
