What is “aluminum curtain wall”?

Last Updated: 2023-04-19

The aluminum veneer curtain wall is made of high-quality high-strength aluminum alloy sheet, the common thickness is 1.5, 2.0, 2.5, 3.0MM, the model is 3003, and the state is H24. Its structure is mainly composed of panels, reinforcing ribs, and corner yards. The corners can be bent and stamped directly from the panel, or riveted to the small edge of the panel. The reinforcing rib is connected with the welding screw on the back of the panel (the screw is directly welded on the back of the panel), making it a solid whole, which greatly enhances the strength and rigidity of the aluminum veneer curtain wall, and ensures the flatness and wind resistance and shock resistance in long-term use. ability. If sound insulation is required, high-efficiency sound insulation materials can be installed inside the aluminum panels.

Aluminum veneer is divided into two types in terms of specifications: aluminum veneer with a thickness of less than 1.2mm is called aluminum gusset sheet (also called aluminum square sheet), and aluminum veneer with a thickness of more than 1.5mm is called aluminum veneer (also called aluminum veneer). curtain wall).

CategoryComposite aluminum sheetAluminum alloy veneer
MaterialTwo layers of 0.5mm thick pure aluminum sheets are sandwiched between PVC or PEC plastic and rolled and heat-sealed.2- -3mm aluminum alloy sheet
Fluorocarbon coatingOne-time roll printing, the coating thickness is generally 20um2 or 3 sprays are completed, and the coating thickness is generally 30-40um
ColorA variety of colors can be selected. The color system is mainly divided into a single color system and a magic color system. The surface of the patented color prodsuct is attached to a film layer, which has excellent durability and good color uniformity.Colors can be selected arbitrarily according to the design and the owner’s requirements
TightnessFour-cornered openingFour corner welding
Wind resistanceThe wind pressure resistance is small, and the wind pressure resistance of the imported composite sheet is extremely high.High resistance to wind pressure deformation, easy to deform
Thermal denaturationFor the composite board processed by the ordinary gluing process, the expansion coefficient of the aluminum board and the plastic is quite different, and it is prone to foaming and peeling.The same material, the wall panel itself has no effect when the temperature changes
Lightning resistanceNot resistant to lightning strikes, it is difficult for the strong current to ground through the composite aluminum sheet, and the 0.5mm thick aluminum sheet will be broken downIt can be used as a good conductor of electricity to quickly transport the huge current of lightning strikes to the ground through the building grounding system.
ProcessabilityIt can be processed on-site and can cope with dimensional changes caused by on-site construction errorsIt is prodsuced in a factory, adapts to the poor error of on-site construction, and has high requirements for secondary design.
YieldGenerally 80%-95%100%
YieldThe groove is manually operated on site. If the depth of the groove is not well controlled, the outer aluminum sheet will be damaged, and the bending will break, resulting in waste prodsucts. The yield is generally 96% to 98%.Made in the factory, the finished prodsuct rate is 100%
Construction QualityBecause the wall panels are mostly processed on site, the quality control conditions are poor, and the quality of the wall panels will affect the construction quality.The prodsuction plant controls the prodsuction quality according to international standards, and the quality of the wall panels is reliable, which provides the premise to ensure the construction quality.
Environmental protectionThe selection of the core material is related to the general core material will prodsuce harmful gases when exposed to high temperature, which is not fireproof and difficult to recycle.Fireproof, easy to recycle, do not pollute the environment.
Scope of applicationSuitable for curtain wall engineeringSuitable for facade decoration, elevated corridors, pedestrian bridges, low-rise curtain walls

Aluminum sheets for construction include single-layer aluminum sheets, composite aluminum sheets, and other materials. Single-layer aluminum panels (also known as single aluminum panels or pure aluminum panels) are usually used in architectural decoration projects. Aluminum curtain wall is a form of the curtain wall. Simply put, it is made of aluminum sheets instead of glass. Aluminum curtain walls are mostly used for retaining walls and walls without lighting. Foreign aluminum curtain walls have always used single-layer aluminum sheets.

The aluminum panel curtain wall has a unique texture, rich and durable colors, and a diverse appearance. It can be perfectly combined with glass curtain wall materials and stone curtain wall materials. Its perfect appearance and excellent quality make it popular among car owners. Its lightweight is only one-fifth of marble and one-third of glass curtain wall, which greatly reduces the load of the building structure and foundation, with low maintenance cost and high-cost performance.
