ASTM Steel Grating of Heavy Duty Grates

ASTM Steel Grating Welded Heavy Duty Grating

Welded Heavy Duty Gratings are designed to service applications subject to heavy rolling and static loads such as highways, plant floors, loading docks, inlet covers, and airports. Since conditions can range from smaller forklift to large truck or aircraft traffic, heavy duty gratings are manufactured in a wide range of bar sizes and spacings.

Design Criteria

Vehicular loads are designed in conformance with current AASHTO specifications for classifications H-15 through H-25. Automobile and forklift loads are similarly evaluated with loads calculated and distributed in accordance with the "Maximum Traffic Conditions" presented below. 

If your application is not adequately addressed by these load conditions, please contact us and we will gladly assist in the selection of an appropriate heavy duty grating for your specific need.

Materials & Spacings

Heavy duty gratings are manufactured in carbon steel and 300 series stainless steels. Carbon steel products are available bare (no finish), painted with manufacturers standard paint, or hot dip galvanized. Stainless steel products are available mill finish, commercially cleaned, or electro-polished. Below you will find a table of spacings for our most popular products.
