Expanded metal is a kind of metal stock that features diamond-shaped patterns that are produced by simultaneously slitting and stretching of the material. The standard form of this material is known as raised expanded metal, because of its elevated diamond pattern.
Aluminum expanded metal sheet is much more lightweight than the steel and stainless steel expanded metal sheet. Aluminum expanded sheet has excellent anti-corrosion and rust resistance, which can be adopted in the salty, high temperature and other harsh environments.
