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.
Serrated grating provides maximum slip resistance.
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.
To Order: For custom sizes, please specify width and length. Note: Grating less than 17" long is reinforced with banding.

Fasteners for Metal Bar Grating
Secure grating to your support structure.
Swivel locks are easy to install, adjust, and remove—tighten the bolt and the fastener swivels into place.
Saddle clips bridge two bearing bars. Fasteners require a hole in the support structure as well as a threaded stud and hex nut (not included).
C-clips hook onto the support structure and are connected by a bolt to the plate on top of the grating. They tighten from above the grating for easy installation.
Connectors tie two sheets of bar grating together. They hold edges of sheets together as you walk, reducing trip hazards.

Plank Grating
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 are serrated to provide maximum slip resistance.
Styles B and C have projections to provide good slip resistance that's more comfortable than serrated grating.

Metal Bar Grating Stair Treads
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 treads are more corrosion resistant than galvanized steel. Plus, they're lightweight, nonsparking, and nonmagnetic.
