Aluminum Expanded Metal with Decorative Effect
Aluminum expanded metal is made from solid aluminum sheet that has been simultaneously slit and stretched, forming non-raveling mesh with uniform diamond shaped openings. It is lighter but more rigid than an equal weight of solid aluminum sheet. It won't unravel and could hold its shape for many years under normal circumstances. What makes aluminum expanded metal popular is that it's economical and versatile.

Aluminum is silver-colored, ductile and low density that finds use in a wide variety of commercial applications. It can be strengthened by adding appropriate alloying elements such as Cu, Mg, Mn, etc. 3003 aluminum is the most widely used for it has good corrosion resistance and a highly polished finish, which makes it an attractive choice for decoration applications. Common uses of 303 aluminum expanded metal involve fire screen, ventilation, security mesh, ceiling tiles, filter screen, etc. Other types of aluminum alloys include 5005, 5052, etc.

Feature

It has light weight for easy transportation.
It is not easily bent, and suitable for security mesh applications.
Decorative properties for ceiling or room dividers.
Good corrosion resistance for long service life.
