I believe that customers who are familiar with aluminum alloy decorative materials should have heard of the name of indoor aluminum veneer. In fact, the boundary is very vague. Generally, according to the thickness of aluminum veneer, we can simply distinguish the indoor and outdoor uses. For example, the thickness of aluminum veneer for external wall is 2.0 mm, 2.5 mm and 3.0 mm, which can resist wind and oxidation. And indoor wall aluminum veneer, if installed in the height of the crowd can not touch, can use 1.5mm thickness, otherwise too thin easy to bump deformation. The interior ceiling board can be decorated with 1.0-1.2mm board according to the demand, because this thickness is the most suitable modeling material for indoor ceiling, which will not deform due to too thin, and will not reduce the safety of the ceiling system due to too heavy, and can make up for the single decoration effect of Engineering ceiling. Of course, if the thickness is less than 1.0 mm, it can not be called aluminum veneer. It is generally called aluminum ceiling, decorative hanging board, etc.
The difference between indoor and outdoor aluminum veneer can be judged not only according to the thickness of the panel, but also according to the customer's paint coating on the surface of the aluminum veneer curtain wall. If it is powder paint spraying, it is generally used for interior decoration aluminum veneer. If it is fluorocarbon baking paint, it is mostly outdoor aluminum veneer. However, some local customers use expensive fluorocarbon baking paint for interior decoration. Of course, the above classification method is not completely accurate. Many projects mainly use different surface processes due to the budget constraints of project cost and the needs of site use. For example, many model houses will be demolished within 1-2 years, and the decorative aluminum plates such as advertising signs and image walls will be redecorated in three to five years. The powder baking process generally takes 10 years to appear some fading phenomenon. Therefore, many engineering decorative aluminum plates are mainly made of powdered paint.
Although there is no distinction between indoor and outdoor aluminum veneers in principle, a series of ceiling decoration materials, such as modeling hanging board, modeling carved board, aluminum strip gusset plate, are considered as indoor special-purpose. As long as the thickness of decorative panels reaches the safety requirements of wind resistance and earthquake resistance, there is no difference between indoor and outdoor. According to the engineering design requirements, different schemes can be adopted according to different regional environment. Generally, when customers make inquiries, we will consult the decoration site of materials, so as to give reasonable suggestions.
