Expanded Metal Basics
Expanded metal is a sheet of metal stretched on an expanding machine to make it thinner. It has perforations or openings in various shapes. Diamond openings are the most common, though they may also be circles, squares, ovals, or hexagons.
- Standard Expanded Metal: Standard expanded metal, also called raised expanded metal, has slightly raised diamond-shaped openings. Standard expanded metal is suitable for enclosures, decorative elements, and support. Suppliers of walkways, fences, and grates use architectural expanded metal.
- Flattened Expanded Metal: Flattened expanded metal is produced by rolling standard expanded metal into a smooth surface. It is suitable for security, support, enclosures, and decoration. Manufacturers of security fences, machine guards, or similar products rely on an expanded metal supplier.
- Expanded Metal Grating: Expanded metal grating is sturdy. It's manufactured using the automatic weld-forge method, joining the bearing bars to the cross bars. It is available with smooth or serrated surfaces.
