Round Hole Hot Dipped Galvanized Mild Steel or Carbon Steel
Perforated Metal Sheet
Round perforated is a sheet or coil of material made from metal or plastic that
contains holes punched by a die. The shape of the hole is determined by the shape of the die. For perforated with a round
hole pattern, the die is circular. The die’s diameter can vary from
approximately twice the thickness of the material being punched to
over two inches.
Material:
We specializes in manufacturing round hole perforated sheets in
various high quality materials including steel ( mild steel or
carbon steel, no painting, galvanized or PVC coated), stainless
steel, aluminum, copper and brass or other materials as your
request.
Round hole perforated sheets are the most common and most requested. There are several types of
hole diameters: very small, medium and large size. Hole pattern is
of primary importance: the most popular arrangement is the 60
degree angle pattern, which combines a high rigidity and a decent
proportion between open and full areas. The 90° pattern is equally
popular, above all for aesthetic needs whereas the 45° pattern is
now almost disused.
Round hole perforated sheet offers the widest options of hole sizes, gauges, materials and
sheet size for all types of applications. For example:
* Cladding and ceiling panels
* Sunshade and sunscreen
* Filter to sieve seed, stone and other bulk materials
* Decorative banister
* Protective fences of overpasses and machine equipments.
* Balcony and balustrade panels
* Ventilation sheet, such as air condition grilles
