Expanded Metal
Expanded metal is formed from a single sheet slit and stretched into a rigid diamond pattern — no welds or wefts to come loose, and a high strength-to-weight ratio. We stock standard (raised) and flattened expanded metal in plain steel, galvanized, aluminum, and 304/316 stainless.
It's the go-to for walkways and platforms, machine guards, grilles and screens, security screening, fencing, and filter backing. Flattened expanded metal gives a smooth, level surface for facades and enclosures.
Cut to size and stocked in Hayward, California. We've been at it since 1938, when we started on Howard Street in San Francisco. Browse the diamond sizes below or request a quote.
