What Is Steel Bar Grating
Types of Steel Bar Grating
Type “W” – Welded Steel Grating
Manufacturing: Forge-welded rectangular bearing bars and drawn cross bars.
Applications: Most cost-effective option for general industrial flooring, catwalks, and maintenance platforms.
Standard Spacing: 19-W-4 (80% open area).
ADA Options: 11-W-4 and 7-W-4 with 3/16” bearing bars.
Strength: Positive fused welds ensure long service life under demanding conditions.
Type “SL” – Swage Locked Steel Grating
Manufacturing: Hollow tube cross bars swaged into pre-punched bearing bars.
Appearance: Flush surface, ideal for architectural and public-use settings.
ADA Conformity: 7-SL-4 spacing with 3/16” bars meets accessibility standards and is suitable for high-heel pedestrian areas.
Best For: Municipal walkways, architectural infill panels, and pedestrian zones.
Type “DT” – Dovetail Pressure Locked Steel Grating
Manufacturing: “Egg-crate” assembly locked under hydraulic pressure.
Design: Features deeper cross bars for visual appeal and strength.
Common Uses: Sunshades, façades, stair rails, and infill panels in modern architectural projects.
