Boasting favorable decoration effect, satisfying anti-rust performance and long service life, aluminum sheet for wallboard have become more and more popular in building decoration. However, there are so many aluminum sheet suppliers in market. How to judge the quality of aluminum sheet for wallboard and choose a reliable supplier? Here are some tips.

First, choose a familiar or reliable brand. If you have problem with choosing suppliers, please refer to Tips for Choosing Reliable Aluminum Sheet Coil Suppliers in China. We will just skip this part here. Second, check steel seals of boards and frames. If wall boards and frames come from different aluminum sheet factories, it will affect installing precision. Mature factories produce ceiling frames as well as boards, both of which are commonly stamped with seals. Those without seals probably come from small factories who apply recycled aluminum sheet with harmful elements like lead and mercury. Third, check the thickness and quality of aluminum sheet wallboard. Expert say the most suitable thickness for  aluminum sheet for wallboard should be between 0.6mm and 1.0mm, not the thicker the better as some people think. Some boards may be thick enough, but almost half of the thickness is disguise of coverage layer, which is very deceptive for some inexperienced customers. To check the quality of a piece of  aluminum sheet for wallboard, one can knock it with the back of his or her fingers. If it gives off clear ringing noise, it should be of good quality. If it gives off heavy depressing noise, you had better not choose it. Fourth, check the base coat of  aluminum sheet for wallboard. Base coat functions to protect the board from water, air or rusting bacteria. Wallboard of high quality is evenly coated, without tiny gray spots (the part which has not been covered by base coat). Fifth, check the gloss and thickness of coverage film. If the film is very bright, it’s not a good thing. Qualified boards are always with smooth even film of good refection. Normally speaking, excellent coverage film is only 0.10 to 0.15 thick.
