As a new type of decorative material, aluminum composite panel has many excellent properties. It is widely used in social life. Aluminum composite panel have strong adaptability whether it is outdoors or indoor. Of course, this is not only because the performance of the aluminum composite panel is good, it is also important to choose the thickness and specifications. So what are the thicknesses of aluminum composite panel for different purposes? I hope the following content can be used for your reference.
The aluminum composite panel has good weather resistance, high durability, convenient construction, good plasticity, strong fire resistance, good flatness, rich color and customization. It is a very good and cost-effective building material. It is easy to process and shape. It not only has high processing efficiency, but also has short construction period, which can realize cutting, slotting, drilling, band sawing, processing and countersunking, cold bending, cold folding, gluing bonding, etc., and the final finished product is in excellent quality.
The use of aluminum composite panels is very wide
Different applications have different thickness requirements for aluminum composite panels. Generally speaking, the common total thickness of ordinary aluminum composite panels is 3mm, 4mm and 6mm, etc. The size of the standard edition is generally 1220*2440mm. In addition, the following thickness standard data by application can be referred to:
1. Aluminum composite panels for exterior wall decoration or advertising signs: The upper and lower aluminum plates are generally made of rust-proof aluminum. The coating is usually coated with fluorocarbon or polyester. The thickness should be above 0.2mm, and the total thickness added. Can’t be less than 4mm.
2. Indoor aluminum composite panels: The minimum thickness of the upper and lower aluminum panels shall not be less than 0.1mm, generally about 0.2mm, and the total thickness is generally 3mm. The coating may be polyester coating or acrylic coating.
3. Aluminum composite panels for building curtain wall panels: According to the requirements of GB/T3880, the panels are generally made of 3000, 5000 series aluminum alloy sheets. The coating is coated with fluorocarbon resin, and the minimum thickness of the upper and lower aluminum sheets cannot be Less than 0.5mm, and the total thickness should be more than 4mm.
How is the thickness of the aluminum composite panel measured?
Generally, a thickness measuring instrument having a minimum score of 0.01 mm is used to measure the thickness at least 20 mm inward from the edge of the plate, and these measuring points should include at least a plurality of thicknesses at the four corner portions and the four-point midpoint portion. The limit error between all measured values and the nominal value is taken as the final result.
The above is a description of common specifications, measurement methods and related issues regarding the thickness of aluminum composite panels.
