With the development of the construction industry, aluminum veneer, with its simple, elegant, lightweight, and high-end design, has been favored by a wide range of consumers. However, the quality of aluminum veneer on the market varies greatly, and prices are also diverse. It can be challenging for laymen to choose aluminum veneer for exterior walls. Next, let me introduce some knowledge about the thickness and selection of aluminum veneer.

What is the thickness of the aluminum veneer for exterior walls?

In general, according to the industry standard for aluminum veneer curtain wall thickness, the difference between the thickness of the substrate and the finished product is 0.05mm. Customers can compare the above data with their own coating requirements and measure the thickness of the aluminum veneer they purchase to confirm whether the thickness of the aluminum veneer meets the industry standard.

How to choose and purchase aluminum veneer for exterior walls?

1. Firstly, the quality of aluminum veneer does not solely depend on its thickness, but rather on the texture of the aluminum material. The surface treatments of aluminum veneer include electrostatic spraying, baking paint, roller coating, pearlescent roller coating, and laminating. Among them, electrostatic spraying and baking paint have a short service life and are prone to color differences; roller coating and pearlescent roller coating have a medium service life and exhibit no color differences; laminated boards can be further divided into ordinary film and imported film, with the former having a shorter service life than roller-coated boards, while the latter can generally maintain its color for up to 20 years.

2. Secondly, it is important to understand the surface treatment technology of aluminum veneer. Currently, after chromizing treatment, fluorocarbon spraying treatment is generally applied. The fluorocarbon coating finish and varnish are made of polyvinylidene fluoride resin. They are generally divided into two-coat, three-coat, or four-coat systems. Currently, fluorocarbon coatings have excellent corrosion resistance and weatherability, capable of resisting acid rain, salt spray, and various air pollutants. They have excellent heat and cold resistance, can withstand intense ultraviolet radiation, and can maintain long-term non-fading and non-chalking properties with a long service life. It is recommended to use boards with fluorocarbon spraying.

3. We should also pay attention to the craftsmanship. Craftsmanship refers to the bonding between the board and the surface layer, which is often overlooked by consumers. Poor craftsmanship can significantly affect the product's service life. It is recommended to inquire with the manufacturer when selecting aluminum veneer.
