Comparison of composite aluminum plate and aluminum alloy veneer

Composite aluminum plate——Two layers of 0.5mm thick pure aluminum plate are sandwiched by PVC or PEC plastic, rolled and heat-bonded.
Aluminum alloy veneer - 2 ~ 3mm aluminum alloy plate.

Fluorocarbon coating
Composite aluminum plate - made by one-time roll printing, the coating thickness is generally 20μm.
Aluminum alloy veneer - 2 or 3 times of spraying, the coating thickness is generally 30-40μm.

Aluminum Composite Panel——A variety of colors can be selected. The color system is mainly divided into monochrome and magic color. The surface of the patented color product has a film layer, which has excellent durability and good color identity.
Aluminum alloy veneer - can choose any color according to the design and the requirements of the owner.

Composite aluminum plate—the domestic plate is about 10 years old, and the color and strength of the imported plate can reach more than 20 years, free of maintenance.
Aluminum alloy veneer - up to 15 years, most of which are deformed due to weather and wind pressure, and the color of the board surface is spent.

Composite aluminum plate - open shape at four corners.
Aluminum alloy veneer - four corners are welded tightly.

Wind resistance
Composite aluminum plate - the resistance to wind pressure is small, and the imported composite plate has extremely high wind pressure resistance.
Aluminum alloy veneer - strong resistance to wind pressure deformation, easy to deform.

Resistance to temperature change
Composite aluminum plate——composite plate processed by ordinary gluing process, the expansion coefficient of aluminum plate and plastic is quite different, and foaming and peeling are prone to occur.
Aluminum alloy veneer - the same material, the wall panel itself has no effect when the temperature changes.

Lightning resistance
Composite aluminum plate - not resistant to lightning strikes, strong current is difficult to ground through the composite aluminum plate, and the 0.5mm thick aluminum plate will be broken down.
Aluminum alloy veneer - can be used as a good conductor of electricity, and quickly transport the huge current of lightning strikes to the ground through the building grounding system.

Composite aluminum plate - can be processed on site, and can cope with dimensional changes caused by on-site construction errors.
Aluminum alloy veneer—made by the factory, poor adaptability to on-site construction errors, and high requirements for secondary design.

Composite aluminum plate - generally 80% to 95%.
Aluminum alloy veneer - 100%.

Composite aluminum plate—Manually plan the groove on site. If the depth of the groove is not well controlled, the outer aluminum plate will be damaged, causing the bending to break and resulting in waste products. The finished product rate is generally 96% to 98%.
Aluminum alloy veneer - made by the factory, the finished product rate is 100%.

Construction Quality
Composite aluminum panels——Because the wall panels are mostly processed on site, the quality control conditions are poor, cutting corners and shoddy products are easy to appear in this link, and the quality of the wall panels will affect the construction quality.
Aluminum alloy veneer - the production plant controls the production quality according to international standards, and the quality of the wall panels is reliable, which provides the premise to ensure the construction quality.

environmental protection
Composite aluminum plate - the selection of core material is related. Generally, the core material will produce harmful gas when exposed to high temperature. It is not fireproof and difficult to recycle.

Aluminum alloy veneer - fireproof, easy to recycle, and does not pollute the environment.

scope of application
Composite aluminum plate - suitable for curtain wall projects.
