FAQ
Expanded metal can be produced using various materials that can be 'stretched' thanks to their mechanical characteristics.
The most commonly used materials in the construction industry are undoubtedly carbon steel and Sendzimir carbon steel. Aluminium is used for cladding applications in architecture. Expanded metal sheets can also be made from various types of stainless steel (e.g. AISI 304, AISI 316 and others) for applications that require specific resistance properties in high temperature environments or corrosive atmospheres.
Expanded metal and perforated metal are both 'open' materials. Expanded metal is produced using a 'slitting and stretching' process without wasting any of the raw material; perforated sheet metal, on the other hand, is obtained by a 'punching' process resulting in metal scrap. Another difference between these materials is the thickness: expanded metal has a three-dimensional shape that also adds to its strength. Perforated sheet metal is flat, with a constant thickness. Expanded metal can be used instead of perforated metal for many applications.
