FAQ

Q1: Can I customize different RAL colors for the coated side besides standard white?

A: Yes. Regular white options include RAL 9003, RAL 9010, RAL 9016; all colors from RAL Classic card are available for customization. Matte or glossy surface finish can also be selected as requested. The reverse side keeps original uncoated mill aluminum finish permanently.

Q2: What coating types do you offer for the painted surface?

A: Standard option is weather-resistant polyester coating for regular inland construction use. PVDF coating is optional for coastal high-salt, high-corrosion areas across North America to extend anti-UV and anti-fading lifespan.

Q3: Are the dimensions produced following inch specifications for US & Canada markets?

A: Absolutely. We supply mainstream imperial sizes such as 0.025” thickness, customizable coil width and outer diameter, fully matching local processing and construction drawing requirements.

Q4: Will the coating peel off during bending and roll forming processing?

A: Our paint features strong adhesion. Under normal stamping, bending and slitting operations, the coating stays intact. We can provide coating adhesion test reports for North American project inspection.

Q5: How about packaging for ocean shipment to USA and Canada?

A: We adopt inner waterproof plastic film + kraft paper wrapping, then fixed on export wooden pallets. It effectively prevents surface scratches, aluminum oxidation and paint damage during long sea freight transit.

Q6: What main applications is this aluminum coil suitable for?

A: Widely used for rain gutters, roof flashing, wall trim, ventilation ducts, signage blanks and mechanical housing, ideal for construction contractors and metal fabricators in North America.

Q7: Can you provide material certification for local customs clearance?

A: Yes, we can supply mill test certificates (MTC), coating inspection documents and other papers to support US and Canada customs clearance and project acceptance.
