Square hole Perforated Metal

Hole: round, length, square, scale hole, hexagonal hole, plum blossom and so on.

Technological process:
is a sheet or coil of material made from metal that contains holes punched by a die. The shape of the hole is determined by the shape of the die. For perforated with a square hole pattern, the die is square. The die's width can vary from approximately twice the thickness of the material being punched to over two inches.

Characteristics:
1. Can be readily formed
2. Easy installation
3. Can be painted or polished and anodizing.
4. The thickness of materials is wide range from 0.3mm-8mm.
5. Largest selection of hole size patterns and configurations
6. Uniform sound abatement,
7. Attractive appearance,
8. Light weight,
9. Durable,
10 Superior abrasion resistances
11. Accuracy of size

Application: Our production of punching-hole screening board is widely used in protecting from ambient noise where the highway, railway and subway come through the city. It can also be used in building wall power station .factory ceiling wall plate and other source of noise in order to sound absorption.
