Product Description

Heavy Duty Hot DIP Galvanized Steel Bar Grate Floor Grating

Hot Dipped Galvanized Heavy Duty Steel Grating 70mm x 6mm Bearing Bar

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 these conditions can range from light-duty forklifts to heavy-duty truck or aircraft traffic, heavy duty gratings are manufactured in a wide range of bar sizes and spacings.

Materials & Finishes

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.

Banding

Heavy duty gratings are commonly subjected to shock and impact loads and it is highly recommended that all open ends be banded. The welded band bar helps distribute impact loads and minimizes distortion when subjected to repetitive traffic patterns.

Serrated Surface

Optional serrated bearing bars enhance skid resistance. Consider this surface for applications subject to the accumulation of liquids or lubricants or inclined grating installations.

How to Specify Heavy Duty Bar Grating

Select type of grating
- "W" for Welded Steel Grating
- "WS" for Welded Stainless Steel Grating
Select bar spacing from table above
Select bearing bar size from Load Tables
Specify Plain or Serrated surface
Specify banding and any additional trim required
Specify finish
- Bare steel (no finish)
- Painted (red, black, silver, other)
- Hot Dip Galvanized (per ASTM A-123)
- Other
Specify fasteners (if required) - Banding / Layout / Fasteners
