what is Perforated aluminum plate?

Perforated aluminum plate refers to pure aluminum or aluminum alloy material made by pressure processing (shear or saw cut) to obtain a rectangular cross-section, uniform thickness of rectangular material.

The perforated board is widely used in real life, and can be used as a decorative board (curtain wall board, wall sound-absorbing board, and ceiling decoration), beautiful and generous. Can be made into a variety of vessels, has corrosion resistance, durable.

Tips on punching aluminum plate

  • The thickness of perforated aluminum plate is generally 0.5mm–3.5mm.
  • The thickness of perforated aluminum plates commonly used in curtain walls and ceilings is usually greater than 1.5mm thick.
  • When the punching rate is greater than 50%, in order to ensure the flatness and effect of the plate surface, an aluminum plate with a thickness of less than 3.0mm cannot be used.

The current situation of punched aluminum plate

  1. The most common is the hole diameter of 6mm and the spacing of 15mm.
  2. According to the current mechanical equipment, the maximum perforation rate can reach about 65%, and the size of the perforated plate is required to be within the range of 1500*3000. If it exceeds this range, the perforation requires secondary positioning.
  3. The higher the perforation rate of the perforated aluminum plate, the greater the influence on the flatness of the formed aluminum plate, and the inspection standard is lower than the corresponding regulations of the normal aluminum plate.

Advantages of perforated aluminum sheet

  1. As the outer skin of the building, the impact of the perforated aluminum plate on the ventilation, shading, lighting and other aspects of the building can directly or indirectly affect the thermal performance of the building.
  2. Light weight and high strength.
  3. Corrosion resistance and strong plasticity.
  4. The film formed by the used coating has good non-adhesion, which is convenient for cleaning and maintenance.
  5. The aluminum itself is green and safe, can be recycled and recycled, and is environmentally friendly and energy-saving.
  6. Simple installation and maintenance, saving construction costs.
  7. Good bending strength and good wind pressure resistance.

Aluminum sheet plate standard export packing

  • The aluminum plate is paperclip or laminated to ensure that the surface of the aluminum plate is intact and free of scratches;
  • Plastic film ( HDPE, PVC, PE or PET etc ) protection or hard kraft paper wrapping is used to prevent moisture and rain to ensure that the aluminum plate is clean and free of dirt during transportation (each package has a moisture-proof desiccant to ensure the quality of our products in East China and South China, where there is more rain);
  • Installed with wooden brackets and reinforced with steel straps to avoid collision during transportation and to ensure the geometry of the aluminum plate remains unchanged;
  • For export products, we use wooden boxes and pallets with fumigation mark for packaging;
  • We can also pack according to other packaging requirements of customers;
