Tinted Aluminum Mirror

Aluminum Mirror is also called aluminized mirror, aluminum mirror, glass mirror, mirror glass, mirror plate glass.High-grade float aluminum mirrors can be made into colored mirrors of various colors to increase different decorative effects, such as gray mirrors, brown mirrors, green mirrors, blue mirrors, etc.The thickness is from 1.1mm to 8mm, and the maximum size of the aluminum mirror plate is 2440x3660mm (96 X 144 inches).Market aluminum mirrors are mainly used for: cosmetic mirrors, furniture, etc.


In addition, we also sell Silver Mirror glass, silver mirror commonly known as waterproof mirror, mercury mirror, silver-plated mirror on glass surface, glass mirror, mirror glass, etc. Silver mirrors are widely used in furniture, handicrafts, decoration, bathroom mirrors, cosmetic mirrors, optical mirrors, and car rearview mirrors.
