What is the thickness of the aluminum-plastic plate of the general door head?
The thickness of aluminum+the thickness of plastic core material is the thickness of the board: 2MM~8MM. 3MM and 4 mm commonly used at home and abroad; Foreign countries also need 5MM and 6MM plates, and now 8MM thick aluminum-plastic plates can also be produced. The thickness of the core material is adjusted according to the thickness of the plate and the thickness of aluminum in production.

Aluminum-plastic plate for building curtain wall: the minimum thickness of upper and lower aluminum plates is not less than 0.50 mm, and the total thickness is not less than 4 mm. The material of aluminum should meet the requirements of GB/T3880. Generally, 3000 and 5000 series aluminum alloy plates should be used, and the coating should be fluorocarbon resin coating.

Aluminum-plastic panels for exterior wall decoration and advertising: the upper and lower aluminum panels are made of rust-proof aluminum with a thickness of not less than 0.20mm, and the total thickness is not less than 4 mm The coating is generally fluorocarbon coating or polyester coating.

Extended data:

The aluminum-plastic board adopts new technology, which improves the peeling strength of the most key technical index of aluminum-plastic composite board to an excellent state, and correspondingly improves the flatness and weatherability of aluminum-plastic composite board.

The weight of aluminum-plastic board is only about 3.5-5.5 kilograms per square meter, which can reduce the harm caused by earthquake disasters and is easy to carry. Its superior construction can complete cutting, cutting, trimming, bending into circular arc and right angle with simple woodworking tools, and can cooperate with designers to make various changes, so the installation is simple and convenient, and the construction cost is reduced quickly.

In the middle of the aluminum-plastic board is a flame-retardant PE plastic core material, and both sides are extremely difficult to burn aluminum layers. Therefore, it is a safe fireproof material, which meets the fire resistance requirements of building codes.
