Products and specifications
What is the difference between laminated metal and pre-painted steel?
The main difference is the surface material. Laminated metal has a film of polyvinyl chloride (PVC), polyethylene terephthalate (PET) or polypropylene (PP) bonded to the metal sheet. Pre-painted steel is coated with liquid or powder paint and then cured at high temperature. Laminated metal is also called colored steel, pre-finished steel or vinyl chloride coating metal (VCM).
- Film thickness: The film on the surface of laminated metal is typically 50 µm–300 µm (0.05 mm–0.3 mm) thick, compared with 10 µm–150 µm (0.01 mm–0.15 mm) for paint. A thicker film feels more solid and allows a wider range of colors and finer textures.
- Forming: Laminated metal is less likely to crack or suffer coating peeling when bent, stamped or deep-drawn.
- Environment: Manufacturing produces lower emissions of volatile organic compounds (VOC).

How do I choose between acrylic and nano-ceramic anti-fingerprint stainless steel?
The right choice depends on what matters most for your application: color range, or hardness and corrosion resistance.
- Acrylic anti-fingerprint stainless steel (2H pencil hardness, salt spray 1,000+ hours) suits general use environments where color range matters. Colors offered: stainless original, Trendy Black, Tungsten Black, Rose Gold and Champagne Gold.
- Nano-ceramic anti-fingerprint stainless steel (6H pencil hardness, salt spray 1,500+ hours, better solvent resistance) suits applications that need higher hardness and corrosion resistance, such as frequently touched appliance panels. The color currently offered is stainless original.
Pencil hardness for both types is tested under a 750 g load.
