FAQs

FREQUENTLY ASKED QUESTIONS

1. Can you provide product samples, and how to calculate the sample fee and shipping cost?

A: Samples are available, sample fee and shipping cost are confirmed with us according to specification, quantity and transportation method.

2. Do you support OEM/ODM customization, and can you print the company logo?

A: Full-process OEM/ODM customization is supported, logo printing is available, specific details can be negotiated.

3.How to guarantee product quality, and do you accept third-party testing?

A: Strict quality control throughout, pre-production sample confirmation and full inspection before shipment; third-party testing is supported to ensure compliance.

4. What are the common alloy grades of aluminum profiles and which scenarios are they suitable for?

A: Common grades: 6063 (light, easy to process, suitable for doors, windows and awning frames), 6061 (high strength, corrosion-resistant, suitable for industrial and outdoor force-bearing scenarios), customizable on demand.

5. What are the common surface treatment methods of aluminum profiles and their respective advantages?

A: Anodizing (wear-resistant, cost-effective), powder coating (rich colors, easy to clean), electrophoretic painting (corrosion-resistant, moisture-proof), fluorocarbon spraying (excellent weather resistance, suitable for high-end outdoor use).

6. What causes color difference on the surface of aluminum profiles and how to avoid it?

A: Mainly caused by uneven extrusion, anodizing process and raw materials; we avoid color difference and ensure consistency in the same batch through standardized processes and strict raw material selection.

7.What are the standards for the wall thickness of aluminum profiles, and does the wall thickness affect the use?

A: Complies with national standards (e.g., main door and window profiles ≥1.4mm); wall thickness affects strength, thicker walls are more stable (suitable for force-bearing scenarios), standard thickness is sufficient for conventional scenarios.

8. Can aluminum profiles be customized in size and color, and what is the customization cycle?

A: Full size and color customization are supported; conventional cycle 5-10 days, 10-15 days for complex cross-sections/large batches, compatible with OEM/ODM needs.

9.How is the corrosion resistance of aluminum profiles, and can they be used in coastal or humid areas?

A: Corrosion-resistant itself, corrosion resistance is improved after surface treatment, suitable for coastal and humid areas; special corrosion-resistant processes can be customized for extreme environments.

10. What is the general service life of aluminum profiles, and how to maintain them daily?

A: More than 20 years with standardized treatment and normal maintenance; daily cleaning with soft cloth, avoid scratching and strong corrosive detergents, regularly check and repair the coating outdoors.
