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