Performance Comparison of Aluminum Curtain Wall

Material
Composite aluminum plates-two layers of 0.5mm thick pure aluminum plates with PVC or PEC plastic in the middle are rolled and heat sealed.
Aluminum alloy plate -2~3mm aluminum alloy plate.
fluorocarbon coating
Composite aluminum plate-one-time roll printing, the coating thickness is generally 20 m.
Aluminum alloy veneer -2 or 3 times spraying is completed, the coating thickness is generally 30 ~ 40μm.
Color
Aluminum composite board-can choose a variety of colors, color system main points: monochrome system and magic color system (can be arbitrarily selected according to the design and the requirements of the owner), patented color product surface with film layer, good durability, good color identity.
Aluminum alloy veneer-can be arbitrarily selected according to the design and the requirements of the owner.
Life
Composite aluminum plate-domestic plate about 10 years, imported plate color and strength of up to 20 and more years, maintenance-free.
Aluminum alloy and other plates-up to 15 years, mostly deformed due to climate pressure, and the color of the plate surface is spent.
tightness
Composite aluminum plate-four corner opening.
Aluminum alloy and other plates-four corners welded close.
wind resistance
Composite aluminum plate-resistance to wind pressure deformation is small, and the wind pressure resistance of imported composite plates is high.
Aluminum alloy and other plates-large deformation resistance and easy deformation.
temperature degeneration resistance
Composite aluminum plate-composite plate processed by ordinary gluing process, the expansion coefficient of aluminum plate and plastic is quite different, and it is prone to foaming and peeling. However, the film is made of DuPont polymer mucosa, which will not blister or peel off.
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, strong current is difficult to ground through the composite aluminum plate, 0.5mm thick aluminum plate will be broken down.
Aluminum alloy veneer-can be used as a good conductor of electricity, through the building grounding system to the lightning strike a huge current quickly transported to the ground.
Wall Panel Shape
Composite aluminum plate-due to the limitation of material, the domestic process is suitable for processing simple shapes, not suitable for folding female angles, and the bending of <90 degrees is easy to break. some imported composite plates can be processed in a complex way, and can be bent 90-150 degrees.
Aluminum alloy veneer-easy processing into special-shaped plate, bending angle range.
Processability
Composite aluminum plate-can be processed on site, can cope with the size change caused by the construction error.
Aluminum alloy veneer-made by the production plant, adapt to the poor error of the construction site, the secondary design requirements are high.
construction quality
Composite aluminum plate-because the wallboard is mostly processed on site, the quality control conditions are poor, jerry-building and shoddy materials are easy to appear in this link, and the quality of the wallboard will affect the construction quality.
Aluminum alloy veneer-the manufacturer controls the production quality according to international standards, and the quality of the wall panel is reliable, which provides the premise to ensure the construction quality.
Scope of application
Composite aluminum plate-suitable for curtain wall engineering.
Aluminum alloy veneer-suitable for facade decoration, elevated corridors, pedestrian bridges, low-level curtain wall walls and cornices.
Environmental protection
Composite aluminum plate-core material selection is related. Generally, the core material will produce harmful gas when it meets high temperature, which is not fireproof and difficult to recycle. When PLUS core material is selected, the fire rating of composite board is Grade A.
Aluminum alloy and other plates-fireproof, easy to recycle, do not pollute the environment.
