Frequently Asked Questions

We primarily supply Grade 304 and Grade 316L for decorative architectural applications. Grade 201 is available for budget-sensitive indoor projects. All materials comply with ASTM A240, EN 10088, and JIS G4304 standards. Grade 304 is suitable for most indoor environments, while 316L is recommended for coastal, marine, or high-humidity applications due to its superior corrosion resistance.

We offer a comprehensive range of surface finishes including: Mirror 8K (highly reflective), Hairline (HL), No.4 Brushed, BA (Bright Annealed), PVD Color Coating (Gold, Rose Gold, Black, Bronze, Champagne, Blue, and more), Etched Patterns (over 100 designs), Embossed Patterns, Sandblasted, and Anti-Fingerprint (AFP) coating. Custom finishes are available upon request.

Standard sheet sizes are 1000×2000mm, 1219×2438mm (4’×8′), and 1500×3000mm. Thickness ranges from 0.3mm to 3.0mm for sheets. We also offer custom cutting to your specified dimensions. For tubes, we supply round pipes (Ø6–Ø219mm), square tubes (10×10–150×150mm), and rectangular tubes (20×10–200×100mm).

Yes. We offer custom PVD color matching services. Please send us a physical color sample or a Pantone/RAL color code, and our technical team will produce a test sample for your approval before mass production.

Our MOQ varies by product type. For standard finishes (Hairline, No.4, Mirror 8K) in Grade 304, the MOQ is typically 100kg per size/finish. For PVD color coatings, the MOQ is generally 200–500kg per color. We support mixed orders, allowing you to combine different products to meet the MOQ threshold. Contact us for a specific quote based on your requirements.

Yes, this is one of our key advantages. You can mix different grades (304/316L), finishes (Mirror/Hairline/PVD), thicknesses, and even combine sheets with tubes in a single container. This allows you to optimize your inventory and reduce shipping costs per unit.

We use calibrated spectrophotometers to measure and record the exact color parameters (L*a*b* values) of every approved sample. During production, each batch is tested against these reference values. Our PVD chambers are regularly maintained to ensure consistent vacuum conditions, which directly affects color uniformity.
