Metal Bar Grating

Able to support heavier loads than plank grating, bar grating is good for trenches, mezzanines, walkways, work platforms, and floors. This grating has an open design that allows air, light, and debris to flow through. Cross bars hold the bearing bars in place; bearing bars help distribute weight and must rest on supports. Use Fasteners for Metal Bar Grating to secure.

To Order: For made-to-order sizes, please specify width and length. Note: Grating less than 17" long is reinforced with banding.

Smooth, Nonsparking

Aluminum—Aluminum grating is more corrosion resistant than galvanized steel. Plus, it’s lightweight, nonsparking, and nonmagnetic. Note: 4-ft. wide aluminum grating is reinforced with banding.

Metal Bar Grating Stair Treads


Smooth Aluminum	Serrated Aluminum	Mounting Dimensions

Choose these stair treads for greater durability than metal plank grating stair treads. They have an open surface that prevents debris from accumulating. Nosing is textured for traction.

Aluminum—Aluminum treads are more corrosion resistant than galvanized steel. Plus, they're lightweight, nonsparking, and nonmagnetic.

Plank Grating


Style A	Style B

Use plank grating for platforms, stair treads, ramps, and decks. Openings allow light to pass through and water to drain. Cut grating with a band saw, hack saw, circular saw, or shears. Use Fasteners for Plank Grating to secure.

Style A—Serrated


Style A

Style A are serrated to provide maximum slip resistance.
