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 since 1938. Browse the diamond sizes below or request a quote.
