Narrow Opening Welded Steel Grating, 20X100mm, Hot Dipped Galvanized 80 micron, Q235
Narrow Opening Steel Bar Grating - China Factory
Narrow openings give this grating a higher load bearing surface than our standard metal bar grating and reduce the chance of something falling through. Able to support heavier loads than plank grating, bar grating is good for trenches, mezzanines, walkways, work platforms, and floors. It has an open design that allows air, light, and debris to flow through. Cross bars hold the bearing bars in place; bearing bars help distribute weight and must rest on supports. Use Fasteners for Metal Bar Grating to secure.
