Composite aluminum plate-two layers of 0.5 mm thick pure aluminum plates are sandwiched between PVC or PEC plastics for rolling and heat sealing.
Aluminum alloy veneer -2 ~ 3 mm aluminum alloy plate.
Fluorocarbon resin coating
Composite aluminum plate-disposable roll printing, the coating thickness is generally 20 μ m.
Aluminum alloy finish-after spraying for two or three times, the coating thickness is generally 30 ~ 40μ m. ..
colour
Aluminum composite plate-a variety of colors can be selected, and the color system is mainly divided into monochrome system and magic color system (colors can be selected at will according to the design and owner's requirements). Patented color products have a film layer attached to the surface, which has excellent durability and good color identity.
Aluminum alloy veneer-color can be selected according to design and owner's requirements.
life
Composite aluminum plate-domestic plate 10 years, the color and strength of imported plate can reach more than 20 years, without maintenance.
Aluminum alloy veneer-as long as 15 years, mostly due to climate wind pressure deformation, plate color flower.
airtightness
Composite aluminum plate-four corners opening.
Aluminum alloy veneer-four corners are welded together.
wind resistance
Composite aluminum plate-the wind pressure deformation resistance is small, and the imported composite plate has extremely high wind pressure resistance.
Aluminum alloy veneer-strong resistance to wind pressure deformation and easy deformation.
Temperature denaturation resistance
Composite aluminum plate-a composite plate processed by ordinary gluing process, the expansion coefficient of aluminum plate and plastic is quite different, and it is easy to bubble and peel off. However, if the interlayer is DuPont polymer film, it will not bubble and peel off.
Aluminum alloy veneer-the same material, the wallboard itself has no effect when the temperature changes.
Lightning strike resistance
Composite aluminum plate-without lightning protection, it is difficult for high voltage to be grounded through the composite aluminum plate, and the aluminum plate with a thickness of 0.5mm will also be broken down.
Aluminum alloy veneer-can be used as a good conductor of electricity, and can quickly transport huge lightning current to the ground through the building grounding system.
Wall panel shape
Composite aluminum plate-due to the limitation of materials, domestic technology is suitable for processing simple shapes and not for folding internal corners.
Aluminum alloy veneer-easy to be processed into special-shaped plate with large bending angle range.
machinability
Composite aluminum plate-can be processed on site, and can cope with the size change caused by site construction errors.
Aluminum alloy veneer-made by the manufacturer, which has poor adaptability to on-site construction and high requirements for secondary design.
yield
Composite aluminum plate-generally 80% ~ 95%.
Aluminum alloy veneer-100%.
yield
Composite aluminum plate-manual slotting on site, if the groove depth is not well controlled, the outer aluminum plate will be damaged, bent and broken, resulting in waste products, and the yield is generally 96% ~ 98%.
Aluminum alloy veneer-produced by the manufacturer, with a yield of 100%.

construction quality
Composite aluminum plate-because the wallboard is mostly processed on site, the quality control conditions are poor, and it is easy to cut corners in this link, and the quality of wallboard will affect the construction quality.
Aluminum alloy facing-the manufacturer controls the production quality according to international standards, and the quality of wallboard is reliable, which provides a prerequisite for ensuring the construction quality.
application area
Composite aluminum plate-suitable for curtain wall engineering.
Aluminum alloy veneer-suitable for facade decoration, elevated corridors, pedestrian bridges and low-rise curtain walls.
environmental protection
The choice of composite aluminum plate-core material is related. Generally, the core material will produce harmful gas when it meets high temperature, which is not fireproof and difficult to recycle; When the positive core material is selected, the fire protection grade of the composite plate is grade A.
Aluminum alloy veneer-fireproof, easy to recycle and not polluting the environment.
