Profile: Metals, Inc. is a supplier of perforated metals and expanded metals. We also offer wire meshes, stair treads, grating, traction treads, grip strut and safety metal products. Our products are made using carbon steel, stainless steel, galvanized steel, aluminum, bronze and brass. Expanded metal is a product typically used for screening, ventilation, and safety guards. Expanded metal is formed in an expanding press. The basic metal is simultaneously slit and cold-formed, which expands the slits into diamond shaped openings of uniform size and regularity. Expanded metal is a form of metal stock made by shearing a metal plate in a press, so that the metal stretches, leaving diamond-shaped voids surrounded by interlinked bars of the metal. The most common method of manufacture is to simultaneously slit and stretch the material with one motion Flattened expanded metal is manufactured by passing the standard expanded sheet through a cold-roll reducing mill. Perforated metal can take many shapes with numerous choices of perforations. It also help to diffuse light and air.
