3. Core Product Advantages

- Superior Anti-corrosion & Anti-rust Performance

3003 aluminum alloy contains manganese elements to form a dense protective oxide film, effectively resisting rainwater oxidation, humidity erosion and coastal salt spray corrosion. It completely avoids rust, peeling and deformation problems of iron and ordinary aluminum gutters, adapting to all-weather outdoor use.

- Balanced Strength & Excellent Processability

H14 half-hard temper provides moderate structural strength, 20% higher strength than 1000 series pure aluminum. It supports free bending, rolling, stamping and cutting without surface cracking or edge burrs, perfectly matching automated gutter production lines.

- High-Quality Coating & Color Stability

Adopts high-adhesion PE/PVDF coating, with uniform surface color, strong scratch resistance and anti-fading ability. No chalking, discoloration or peeling under long-term ultraviolet radiation and extreme temperature changes, maintaining a neat appearance for years.

- Lightweight & High Safety

Low density of aluminum material reduces building load without compromising structural stability. The material is non-toxic, pollution-free, recyclable, and meets environmental protection standards for architectural materials.

- Long Service Life & Low Maintenance

Excellent weather resistance and oxidation resistance greatly reduce later maintenance costs. It does not need frequent anti-rust painting and repair, saving labor and material costs for building operation.

- Strict Dimensional Tolerance

0.8mm precise thickness control with ±0.02mm tolerance, flat and smooth strip surface, ensuring consistent processing accuracy and assembly compatibility of finished gutters.

5. FAQ

Q1: Why choose AA3003 H14 alloy instead of other aluminum alloys for gutters?

A1: AA3003 H14 is the best choice for gutters. It offers outstanding rust resistance, proper strength and flexibility, with no cracking or deformation during processing.

Q2: What is the difference between PE and PVDF coating?

A2: PE is cost-effective for inland use with 10-15 years lifespan. PVDF features superior corrosion resistance, suitable for coastal areas with 20+ years service life.

Q3: Will the prepainted aluminum strip fade or peel after long-term outdoor use?

A3: No. Premium coating and strict processing ensure excellent weather resistance, no fading, peeling or chalking for long-term outdoor use.

Q4: Can you provide customized size and color?

A4: Yes. Custom sizes, colors and coating types are available to fit your project requirements.
