Heavy Duty Gratings

Heavy-Duty Welded Bar Gratings are specifically engineered to withstand high-impact, concentrated loads typically imposed by industrial vehicular traffic, including forklift trucks and highway-rated vehicles. These gratings are fabricated to meet stringent structural performance requirements in environments where durability and load-bearing capacity are critical.

Typical applications include:

• Linear drainage systems and trench grates
• Sump and vault access covers
• Industrial mezzanine and floor systems
• Airfield drainage infrastructure
• Highway and transportation catch basins

Design parameters conform to the structural strength and deflection limits prescribed in ANSI/NAAMM MBG 534-24. Consideration of fatigue performance under cyclic loading conditions is recommended and should be evaluated by the responsible structural or civil engineer based on project-specific service conditions.
