This article will provide a comprehensive guide to four common steel bar grating specifications: 15-W-4, 22-W-4, 30-W-4, and 38-W-4. If you wish to learn about 19-W-4, we have a dedicated page for it. For ADA compliance, view our page for 11-W-4.
The NAAMMMetal Bar Grating Manual provides architects and engineers with current technical data on bar gratings and stair treads of steel, stainless steel, and aluminum. The information contained is based on sound engineering principles and reflects practices recommended by leading manufacturers in the industry.
Popular for highly corrosive environments and long-lasting architectural applications, stainless steel bar gratings are available with bearing bar spacing ranging from 19/16″ (1-3/16″) to 7/16″ on center and with cross bars at 4″ or 2″ on center.
Metal bar grating is manufactured by welding a series of equally spaced bearing bars to connecting cross-rods using automated forge welding equipment. Bar grating comes in a variety of thicknesses and spacing that can be selected to meet anticipated loads. Bearing bars can be either smooth or serrated
When your project requires strength and durability for heavy-load areas, Vulcraft heavy duty welded steel bar grating is your solution. Common uses for this product include flooring, driveways, subways and tunnel ventilation grilles, curb inlet grates, ramps, and docks.
These calculations show the procedures used to prepare data for metal bar grating load tables. The concentrated midspan and uniform load bearing capabilities of W-19-4 (1-1/2 x 3/16) welded A1011 CS Type B carbon steel grating and the corresponding midspan deflections will be calculated.
