Expanded Metal Mesh and Gratings

Expanded metal mesh or grating 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, catwalks, and working platforms as it is easily cut into irregular shapes and 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.
