Popular patterns of perforation come in Triangle, Five-star, Hexagon, Cloverleaf, Diamond, Square, Dimple and decorative designs. The metal sheets are made with flat plates or anti slippery raised patterns.

The raised checkered or dimpled metal plates are popularly used in safety floor and treading uses.

We make perforated metals out aluminum, stainless steel, galvanized steel, cold-rolled carbon steel, copper, brass and other metals. Perforated sheets can be punched from metal plates and coils providing options of margins and blank areas, along with full perforation styles. A common way to produce perforated metal is using coils. This method provides great flexibility in both design and handling. Perforated coils can be produced faster than perforating sheets.

Standard perforated metal sheets we supply are size 1000 x2000 mm, thicknesses from 0,3 mm up to 10 mm and perforation from 0,3 mm up to 100 mm. Perforation range: round, square and rectangular holes and much more.
Usually holes diameter can not be lower than thickness. Usually the round holes layout is at 60°. Squared and rectangular holes, instead, are aligned.
