Product Introduction
304 perforated stainless steel plate is a metal plate with regular or customized pattern holes such as round holes and square holes on the plate with 304 austenitic stainless steel as the base material, through precision processes such as CNC punching and laser cutting. By controlling the hole diameter of 0.5mm-50mm, the hole spacing accuracy of ±0.1mm and the maximum opening rate of 60%, the balance between lightness and strength is achieved, and at the same time, it has functions such as ventilation and heat dissipation, and acoustic treatment.
From the light and shadow design of building curtain walls, industrial equipment protection, to the weight reduction of aviation interiors, 304 stainless steel perforated plate has become an ideal material in the field of modern industry and design with its versatility and aesthetic value.
304 stainless steel plate with holes
The hole structure of 304 perforated plate is not easy to accumulate moisture and pollutants. After passivation treatment, the corrosion resistance is further improved, and the service life is extended by 3-5 times compared with ordinary perforated steel plate. The perforated design reduces the material consumption (the opening rate can reach 60%), and the weight is reduced by more than 40% compared with the solid plate, while maintaining the structural strength. It is suitable for weight-sensitive scenes such as high-rise building curtain walls and aviation interiors.
The regular hole shape of perforated ss 304 plate can optimize the air circulation efficiency and is used for equipment protective covers and air-conditioning outlets, with both dust-proof and heat-dissipating functions.
