Rhomb Expanded Metal Factory - Foshan, China


As a manufacturer, Rhomb produces raised mesh and flatten mesh expanded metal, gratings, screen and metal mesh in a wide range of metal materials. Expanded Metal is made from sheets of solid metal that are slit and stretched with each stroke of the upper die, forming an opening pattern. The pattern varies by the gauge and type of material and the size of the diamond. The sheets can also be flattened by passing the unflattened material through a series of cold reducing mill rolls.

The production of quality expanded metal requires the use of high quality raw materials and accurate expanded metal presses. At Rhomb, we design and build our expanders. This enables us to produce a higher quality part for our customers.

The lightweight properties and open area percentages of expanded metal allow it to be easily formed for a variety of energy saving applications such as light diffusers, screens, grilles and filters. It is also used as safety gratings, panel security enclosures, guards, fixtures and more.

Expanded metal is available in aluminium, copper, stainless steel, brass, low-carbon steel or zinc coated steel. It can be fabricated for ironing boards, telephone booths, security screens, furniture, air filtration units, switchboard units, trellis work, antennae, animal cages, sun screens, tree guards, ventilating panels, cable trays, room dividers, backgrounds, magazine racks, storage bins.
