1.Perforated metal description

Perforated metal (also known as perforated sheet, stamping plates, or perforated screen) is made through the metal stamping and sheet metal manufacturing process. Sheet metal materials include steel, aluminium, stainless steel, bronze, brass, titanium.

• Material :Stainless Steel ,Plain Steel ,Galvanized Steel,Aluminum, Brass (Copper) ,Phosphor or Bronze,etc
• Hole shape:Diamond, square, triangle,round,hexagonal and decorative patterns
• Production process:Die-perforating-slitting-shearing-roller-leveling-clean-packing.

2.Perforated metal advantages

• Acoustic performance

• Weight reduction

• Radiation containment

• Separation

• Heat dissipation

• Transparency

• Anti-Skid
