Steel bar grating with high strength and firm structure is made up of carbon steel, aluminum steel, or stainless steel. According to the manufacturing methods, it can be divided into four types: welded, press-locked, swage-locked, and riveted gratings. According to the surface shapes, it can be divided into smooth and serrated gratings. With various styles and sizes for choice, steel gratings are widely used in everyday life, such as stair treads, walkways, platforms, floors, various covers, wheeled equipment, security screens, heavy-duty constructions, and so on.
| Main Components of Metal Bar Grating | |
|---|---|
| Span | Total span. |
| Width | Panel width. |
| Bearing Bars | Load carrying main element. |
| Bearing Bars Spacing | Measure from center-to-center of the bearing bars in 1/16″ increments. Standard spacing for industrial flooring is 19/16″ (1-3/16″) on center. Other popular spacings are 15/16″, 11/16″, 1/2″, and 7/16″ on center. |
| Bearing Bars Depth | Ranges from 3/4″ to 7″ depending on anticipated loads. |
| Bearing Bars Thickness | Ranges from 1/8″ to 1/2″ depending on anticipated loads. |
| Cross Bars | Used to Secure the position of bearing bars. |
| Cross Bar Spacing | Measured from center-to-center of cross bars in 1″ increments. Standard spacing is 4″ or 2″ on center. |
We provide four finishes for anti-corrosion treatment of carbon steel bar grating:
Due to discoloration during welding and manufacturing, stainless steel bar grating usually requires a second cleaning:
Steel grating accessories are used to install and fix steel grating. They are very necessary. Steel grating accessories have wear resistance, high strength and resistance to stress, rust-proof performance.

Steel bar gratings are primarily manufactured using carbon steel, aluminum steel, or stainless steel, selected based on the structural requirements and corrosion resistance needed for the specific application environment.
The standard bearing bar spacing for industrial flooring applications is typically 19/16″ (1-3/16″) on center, with alternative spacings such as 15/16″, 11/16″, 1/2″, and 7/16″ available depending on the project load needs.
Hot-dip galvanizing provides the most durable and effective protection against rust and corrosion, strictly executed in accordance with international standards like ASTM A123 or GB/T 13912-2002.
Yes, bespoke configurations including irregular shapes, specialized bearing bar depths, thicknesses, and specific profile shapes (serrated or smooth) can be custom engineered to fit exact site requirements.
Panels are secured using an array of accessories such as saddle clips, G-clips, grate fast clips, weld lugs, Z-clips, and anchor blocks depending on whether the installation requires permanent or removable fixing.
Yes, complimentary product samples are accessible for most grating profiles and specifications to verify load bearing capability, material quality, and surface finish before volume manufacturing.
