Expanded Metal Grating and Mesh

Expanded metal grating or expanded metal mesh is the most practical and economical way to assure strength, safety, and a non-skid surface. Expanded metal grating is ideal for use on plant runways, working platforms, and catwalks, as it is easily cut into irregular shapes and can be installed quickly by welding or bolting.

To select the proper metal mesh for your application consult the load and deflection tables below, if you have any additional questions please give us a call at 215-860-3600

If you are looking for a welded or woven mesh (wire cloth), please look at our wire mesh page.
