Heavy-Duty Expanded Grating is manufactured in thicker gauges for increased strength and durability, making it suitable for structural walkways, platforms, mezzanines, and stair treads. It bridges the gap between light-gauge expanded metal and heavier bar grating, providing a robust yet cost-effective alternative. Aluminum and stainless steel options are available upon request.
