What is Steel Bar Grating?
Steel bar grating provides reliable traction and the ability for liquid, heat, air, sound, or light to pass between levels without the heavy weight of a solid steel plate of the same dimensions. Despite its light weight, bar grating is extremely strong and durable for load-bearing applications such as pedestrian and light vehicle traffic. Because of these characteristics, it’s commonly used in fire escapes, gangways, operating floors, stair treads, drainage covers, and more.
Steel bar grating is available in a variety of bearing bar spacing and thicknesses depending on applications and load requirements. We offer bar grating from ⅛ x 1-¼ to ¼ x 1-½ ” in both a bare and galvanized finish, serrated or smooth. We also offer comprehensive finishing services, such as cutting to length.

Steel Bar Grating FAQs
Bar grating is generally broken into 3 primary types:
- Type W Grating (Welded) – Usually the most economical type, these grates are created by forge welding bearing bars and crossbars.
- Type SL Grating (Swage Locked) – This type of grating uses hollow tube crossbars that go through pre-punched holes in the bearing bars.
- Type DT Grating (Dovetail Pressure Locked) – Using an “egg crate” configuration, these grates have crossbars that fit vertically into slots in the bearing bars.
The span is a measurement of distance parallel to the bars (and perpendicular to crossbars) between supports. For example, the “length” of a piece of grating between 2 beams is the span. The width of a piece of grating is the measurement of the crossbars.
