3015 Al-Mn Alloy Color Coated Aluminum Coil

3000 Series Al-Mn Alloy Color Coated Aluminum Coil is a high-performance color coated aluminum product with 3000 series aluminum-manganese alloy (such as 3003. 3004. 3105) as the base material. It is manufactured through strict processes including degreasing, chemical conversion, painting and high-temperature curing, complying with ASTM B209 and EN 573 international standards. The product integrates the excellent weather resistance, fatigue resistance and processing performance of aluminum-manganese alloy, and the surface coating is firmly bonded, which can adapt to various indoor and outdoor architectural scenarios. It is the preferred cost-effective material in the field of architectural enclosure and decoration, and is widely recognized in global markets such as Southeast Asia, the Middle East and Europe.

Product Features

Superior Weather Resistance: The aluminum-manganese alloy base material forms a dense oxide film, which has excellent resistance to ultraviolet rays and rain erosion. Combined with PE/HDP/PVDF coatings, the outdoor service life can reach 15-20 years, suitable for ordinary outdoor environments in inland areas.

Excellent Processing Performance: It has good ductility and formability, and can be easily processed through stamping, bending, cutting and other processes. The coating remains intact during processing, without peeling or blistering, and is suitable for the production of various architectural components.

Cost-Effective Corrosion Resistance: The aluminum-manganese alloy has inherent corrosion resistance, and the surface color coating further enhances the anti-corrosion effect, which can effectively delay the oxidation and rust of the base material. It has obvious cost advantages compared with 5000 series aluminum-magnesium alloy products and high-end stainless steel materials.

Stable Mechanical Properties: The addition of manganese element improves the strength and hardness of the product, which is higher than that of 1000 series pure aluminum products. It can meet the load-bearing requirements of architectural enclosure and decorative components, and has good fatigue resistance.

Rich Customization Options: Support customization of coating types (PE, HDP, PVDF), colors (optional RAL color card), thickness (0.3-1.2mm), width (1000-1250mm standard, customizable) and surface processes (smooth, embossed), to meet the diverse needs of different projects.

Environmental Protection and Energy Saving: The product complies with REACH and ROHS environmental standards, with low VOC emissions from the coating and recyclable. The surface coating has good light reflection performance, which can reduce building energy consumption and achieve energy-saving effects.

Application Scenarios

Architectural Enclosure System: It is used for wall and roof enclosure panels of ordinary industrial plants, warehouses, civil buildings and other structures, with good wind load resistance and durability.

Rolling Shutter Doors and Windows: As the raw material for rolling shutter door panels and rolling shutter window slats in inland outdoor scenarios, it has excellent processing performance and cost-effectiveness, and can meet the long-term use requirements of residential and commercial buildings.

Ceiling Decoration: Suitable for indoor and semi-exposed ceiling materials in factories, offices, shopping malls and other places, with a variety of color and surface process options to meet different decorative styles.

Other Architectural Decoration: It can be used to produce decorative panels, partition walls, shutters and other components, and is also applicable to agricultural greenhouses, simple prefabricated houses and other auxiliary architectural scenarios.
