Web Wire Mesh is here to help you understand the manufacturing process of Expanded Metal and Perforated Metal.

Expanded metal is produced through cutting and expanding a solid sheet of metal in expanding machines. The expanding machine is fitted with a knife which determines the mesh pattern. The mesh pattern includes: diamond hole,hexagonal hole,architectural hole etc... The expanded metal production contains no welded joints and no woven threads, which contributes to the unique qualities of expanded metal.

Perforated metal is a product that is made from sheet steel, which is then fed through a machine that punches out round holes,square holes,slotted holes,hexagonal holes etc. The holes can be placed in straight rows or staggered to help increase the amount of the openings. Usually the perimeter of the sheet has a boundary where holes are not punched; by doing this it adds stability to the sheet.
