Material comparison of composite aluminum plate and aluminum alloy veneer

Composite aluminum plateAluminium alloy veneer
The materialTwo layers of 0.5mm thick pure aluminum plate, sandwiched with PVC or PEC plastic, rolled and hot bonded2-3mm aluminum alloy plate
Fluorine carbon coatingThe coating thickness is generally 20 μmThe coating thickness is usually 30-40 μm after two or three sprays
colorThere are a variety of colors to choose from, color is basically divided into monochrome and magic color. Patented color products have a layer of film on the surface, good durability, good color identityColor optional according to design and client’s requirements
lifeDomestic plate about 10 years, imported plate color and strength can reach more than 20 years, maintenance freeAs long as 15 years, mostly due to weather wind pressure deformation, panel color flower
enclosedThe four openingsThe four corners are tightly welded
Wind resistanceThe wind pressure deformation resistance is small, and the wind pressure strength of the imported composite plate is very highStrong deformation resistance to wind pressure, easy deformation
Resistance to temperature changesThe expansion coefficient of aluminum plate is quite different from that of plastic, so it is easy to blister and peelThe same material, temperature changes when the wall panel itself has no effect
Ray resistanceLightning resistance, strong electricity is difficult to ground through the composite aluminum plate, 0.5mm thick aluminum plate will be broken downIt can act as a good conductor of electricity, sending huge lightning currents to the ground quickly through the
building’s grounding system
processabilityCan be processed on site, can cope with the size change caused by the construction error on siteMade by the manufacturer, it has poor adaptability to the errors of field construction and high requirements for
secondary design
To realizeGenerally 80%—95%100%
yieldIf the groove depth is not well controlled, the outer aluminum plate will be damaged, resulting in bending and fracture, resulting in waste products. The rate of good products is generally 96%——98%Factory production, yield of 100%
The environmental protectionIt involves the selection of core material. General core material in high temperature will produce harmful gas, not fire, difficult to recoverFireproof, easy to recycle, no environmental pollution
Scope of applicationSuitable for curtain wall engineeringSuitable for facade decoration, elevated corridor, pedestrian bridge, low curtain wall
