30mm I-Beam Welded Steel Bar Grating

Welded steel bar grating is the most popular of all grating types due to its strength, cost-efficient production and ease of installation. Welded bar grating is resistance welded to create a rugged, one-piece constructed panel. Beststeelgratings fabricates grating into specific widths, lengths, curved shapes, incorporates hinged panels, and different finishes to meet project requirements.

Notes
1. U= Safe uniform load. (kN/m2)
2. C= Safe concentrated load. (kN/m)
3. D= Deflection. (mm)
4. In this table, when the safe uniform load is 2kN/m2, the deflection is less than 4mm.
5. The weight is that of 1m long hot-dip galvanized steel grating.
