What Is Steel Bar Grating

Steel Bar Grating is a high-performance flooring and support solution engineered for industrial and commercial environments. Manufactured from ASTM A-1011 mild carbon steel and designed to meet the most demanding applications, our bar grating products combine strength, safety, and versatility. With various fabrication methods—welded, swage-locked, and dovetail pressure-locked—our grating systems ensure optimal load-bearing performance while allowing for drainage, ventilation, and slip resistance.

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.

 Steel Bar Grating

 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.

Steel Bar Grating


 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.
