8011 Color Coated Aluminum Coil

8011 color coated aluminum coil uses 8011 aluminum alloy coil as the base material. Through multiple processes such as degreasing, chemical conversion, coating, baking, and curing, it becomes a composite aluminum material that integrates decorative and protective functions.
Because 8011 aluminum contains higher amounts of Fe and Si, it offers excellent strength, ductility, corrosion resistance, and superior coating adhesion. For this reason, 8011 color-coated aluminum coil is widely used in the construction and manufacturing industries. HAOMEI Aluminum can also produce PE-coated and PVDF-coated aluminum coils.

Features of 8011 Coated Aluminum Coil

1. Corrosion Resistance:
   The coating acts as an effective barrier that prevents water, oxygen, and chemicals from contacting the aluminum substrate, significantly extending service life.

2. Lightweight:
   8011 aluminum has a density of approximately 2.71 g/cm³, helping reduce structural loads in both construction and industrial applications.

3. Excellent Workability:
   The coating is flexible. During bending, rolling, or forming, the coating does not crack or peel.

4. High Decorative Value:
   Available in a wide range of colors, including solid colors, metallic finishes, wood grain, stone grain, and more to support customized designs.

5. Superior Weather Resistance:
   Especially with PVDF coatings, the coil exhibits long-term resistance to UV, acid rain, and pollution, maintaining durable color stability.

6. Safety:
   8011 aluminum is FDA-approved, non-toxic, and suitable for food-contact packaging.

7. Environmental Protection:
   Many modern coatings are eco-friendly and meet green building standards.

FAQ

Q1. Can 8011 color-coated aluminum coils be customized in color and surface texture?
A1:Yes. We can customize according to RAL color cards or customer samples and offer wood grain, stone grain, mirror, brushed, matte, and more.

Q2. What is the difference between PE and PVDF coatings?

A2:PE: Affordable, ideal for indoor or mild environments

PVDF: Superior UV and weather resistance, best for long-term outdoor use

Q3. How should color-coated aluminum coils be stored and transported?

A3:Avoid rain and humid environments; store in a dry and well-ventilated place; lay flat during transportation to avoid collisions and scratches.

Q4. Do you provide samples and customization service?
A4:Yes. Free samples available. Custom thickness, color, width, and coating options. OEM/ODM and export packaging supported.

Q5. What is the service life of 8011 color-coated aluminum coil?

A5:Under normal conditions, the lifespan of a PE coating is 10-15 years, while that of a PVDF coating can reach 20-25 years, depending on the usage environment and maintenance methods.

Q6. Is it suitable for food packaging or bottle cap applications?
A6:Yes. 8011 alloy features excellent ductility and sealing properties. Epoxy or non-toxic PE coatings meet food-grade standards, suitable for pharmaceuticals, beverages, and food packaging.
