A3105 H22 Color Coated Aluminium Coil Aluminium Sheet in Coil for Building

1. Product Introduction

3105 H22 color coated aluminium coil is a high-quality building-grade aluminum rolling material with excellent formability, uniform coating performance and outstanding outdoor weather resistance. The 3105 alloy belongs to the aluminum-manganese series, featuring balanced strength and ductility, while the H22 semi-hard temper provides moderate hardness, making it not easy to crack during bending, stamping and rolling forming. Adopting advanced roller coating and high-temperature curing technology, the surface is covered with durable PE or PVDF protective coating, which effectively resists UV radiation, rain erosion, oxidation and fading. Widely used in building exterior decoration, roofing, wall cladding, drainage system and other construction scenarios, it is a cost-effective and stable decorative & waterproof building material.

3. Product Advantages

Excellent Formability

• 3105 H22 semi-hard temper balances hardness and toughness. It supports bending, rolling, stamping and cutting without coating cracking or base material deformation, suitable for various building profile processing.

Strong Weather Resistance

• High-quality PE/PVDF coating effectively resists ultraviolet rays, high temperature, rainwater and atmospheric corrosion. It maintains stable color and flat surface for a long time outdoors, no fading or peeling.

Uniform & Delicate Surface

• Adopts precision roller coating process with uniform paint film, no color difference, no bubble and no scratch. The decorative effect is stable and high-grade.

Lightweight & Safe

• Aluminum alloy material is lightweight, reduces building load, and features good fire resistance and weather durability, safe for long-term building use.

Cost-Effective & Low Maintenance

• Compared with 3003 high-hard alloy, 3105 H22 has more competitive price while retaining good processing and anti-rust performance, almost no later maintenance cost.

Eco-Friendly & Recyclable

• Non-toxic, pollution-free and 100% recyclable, conforming to green building material standards.

4. Application Range

• Building Exterior Decoration: Exterior wall cladding, decorative aluminum panels, roof decorative materials for residential and commercial buildings

• Roof & Drainage System: Building roof panels, rain gutters, downspouts and waterproof flashing materials

• Architectural Profiles: Processed into aluminum veneers, ceiling panels, curtain wall auxiliary materials

• Industrial & Civil Construction: Factory workshop roof enclosure, temporary building decoration, outdoor waterproof engineering

• Advertisement & Decoration: Outdoor advertising board base, decorative color aluminum sheets

5. FAQ

Q1: What is the feature of 3105 H22 compared with 3003?

A1: 3105 H22 has better ductility and forming performance, more suitable for complex bending processing, with more competitive price for general building decoration.

Q2: How long is the outdoor service life?

A2: PE coating lasts 8–10 years, PVDF coating can reach 15+ years, with stable anti-UV and anti-fading performance.

Q3: Can I customize size and color?

A3: Yes. Custom width, thickness, RAL colors and surface finishes are available.
