Our Leading Coating Technology.

Thicker coating, consistent color and easy-clean surfaces. Each one measured in our own production and compared with typical market product.
PVD coating

Thicker PVD coating

0.30µm
Typical coating thickness, up to 28% thicker than a typical market coil, so the color lasts longer.
See the coating test
Color control

Consistent color

ΔE ≤ 2
Every coil is held below the color difference the eye can see, so panels from different batches match.
See the color data
Anti-fingerprint

Fingerprint-resistant

215solvent rubs
Our anti-fingerprint coating withstood 215 rubs with a strong solvent. The standard requires 100. Typical market AF failed at 70.
See the AF test
Tested to GB/T and ISO standards, with MTR and SGS reports on request.
