Soundproof perforated mesh is a kind of fence project widely used in highway, railroad, subway and other transportation fields. The main role of soundproof perforated mesh is the function of sound absorption and noise reduction, due to the uniqueness of the process can achieve beautiful and generous, long service life and other characteristics, in the building walls, factory plants, subway lines and other fields can be commonly encountered.

Acoustic perforated mesh can produce many different hole types, such as round, oval, oblong, square, triangular, hexagonal, eight holes, plum blossom, diamond-shaped holes and other series of hole types, based on the different hole types in the deep processing process can be formed according to the needs of bending treatment, bending height, bending angle, bending shape and other custom production, cutting of different can be completed according to the size and shape of the user. Due to the special environment in the anti-corrosion treatment is mainly carried out by spray paint, fluorocarbon spraying, electrostatic powder coating. Acoustic perforated mesh can be manufactured from 0.5-20MM sheet metal thickness.

Zhuolida etching can meet the user's manufacturing of micro-perforated mesh etching, etching process precision tolerance can be controlled at 0.01mm, sound insulation perforated mesh is formed by stamping, this is mainly used in larger materials and thicker materials, while in the pursuit of precision instruments on the mesh by means of etching process to complete.
