PE-Coated 1000 Series Aluminium Coil for Roofing, Rainwater Systems, and Flashing

In modern construction engineering, roof protection, rainwater drainage, and overall waterproofing are core aspects of ensuring building lifespan and occupant comfort.

PE-coated 1000 series aluminum coils, with their stable high-purity aluminum substrate and protective advantages of polyester coating, are perfectly suited for three core scenarios: building roofs, rainwater systems, and waterproofing projects, making them a mainstream building material choice for residential buildings, villas, and small to medium-sized commercial projects.

I. 1060 and 1100 Color-Coated Aluminum Coils

Both 1060 and 1100 belong to the 1000 series high-purity aluminum substrate, with an aluminum content far exceeding that of ordinary alloy aluminum materials. They possess a naturally dense oxide film, fundamentally avoiding the problems of steel rusting and coil cracking.

Combined with a precision roller-coated PE polyester coating, the coating has strong adhesion and uniform thickness, making it less prone to peeling, flaking, and cracking during on-site bending and cutting. They are excellent substrates for outdoor waterproofing. However, the material characteristics of the two models differ slightly, and their suitable application scenarios differ.

1060 color-coated aluminum coil is a mainstream material for general engineering applications. It boasts high substrate purity, excellent flexibility, superior processing performance, and outstanding cost-effectiveness. Suitable for most conventional building waterproofing and enclosure applications, it is highly malleable and can be easily processed into various irregularly shaped components to meet diverse construction needs.

1100 pe coating aluminium coil is a high-purity, corrosion-resistant upgraded version. With extremely low impurity content in the substrate, it effectively inhibits micro-galvanic corrosion and offers superior resistance to acids, alkalis, salt spray, and silt abrasion. Its overall weather resistance and corrosion resistance are superior to the 1060 model, making it particularly suitable for harsh outdoor conditions such as humid environments, coastal areas, and industrial zones, with stronger long-term stability.

Both products feature a smooth, dense, self-cleaning, stain-resistant, heat-insulating, and waterproof PE coating. It effectively isolates rainwater, moisture, and dust erosion, maintaining its gloss without fading. Its stable outdoor service life can reach over 10 years. Furthermore, the material is lightweight and easy to install, significantly reducing construction difficulty and subsequent maintenance costs.

II. Roofing Applications

Roofs are constantly exposed to wind, rain, sun, and temperature fluctuations, making them a core weak point in building waterproofing. Two types of PE-coated aluminum coils, 1060 and 1100, can be selected according to specific needs, replacing traditional building materials and achieving long-lasting roof waterproofing.

1060 pe coating aluminium coill: Suitable for residential, villa, and standard commercial roofs, offering high cost-effectiveness. The material is flexible and easy to process, suitable for various flat, pitched, and irregularly shaped roofs. The aluminum substrate is rust-free and deformation-resistant, forming a seamless protection with the PE waterproof coating, providing waterproofing, seepage resistance, heat insulation, and aging resistance, while also being decorative.

1100 Color-Coated Aluminum Coil: Suitable for highly corrosive roof scenarios such as coastal areas, waterfront areas, and industrial areas. Resistant to salt spray and acid/alkali corrosion, effectively preventing material aging, perforation, and damage. It maintains stable waterproofing performance in harsh environments, significantly extending roof lifespan and reducing maintenance costs.

III. Rainwater System Applications

Building gutters, downpipes, and other drainage components are prone to blockage, corrosion, and leakage due to prolonged dampness. Both types of color-coated aluminum coils can be processed into complete drainage accessory sets, solving the common problems of traditional iron and plastic components.

1060 Color-Coated Aluminum Coil: Suitable for inland residential and general commercial drainage systems. Self-cleaning surface prevents siltation and ensures smooth drainage; lightweight material with excellent sealing properties reduces building load, eliminates the risk of detachment and leakage, and offers excellent cost-effectiveness.

1100 Color-Coated Aluminum Coil: Suitable for complex drainage conditions in coastal, high-humidity, and chemical-industrial areas. Immersion-resistant, erosion-resistant, and highly corrosion-resistant, it will not crack or rust in long-term water environments, completely solving the problem of water seepage due to damage to drainage components, and its lifespan is more than 50% longer than traditional materials.

IV. Overall Waterproofing Projects

Building eaves, joints, pipe openings, and other nodes are prone to leakage. Both color-coated aluminum coils have excellent workability and sealing properties, compensating for the defects of traditional coils such as blistering, cracking, and detachment, and are suitable for overall systematic waterproofing construction.

1060 Color-Coated Aluminum Coil: Highly malleable, suitable for conventional building node finishing, flashing, and water-blocking construction, can fit irregular gaps seamlessly, and provides efficient construction, meeting the waterproofing upgrade needs of small and medium-sized buildings.

1100 color-coated aluminum coil: Suitable for high-level, high-difficulty key waterproofing projects. It is resistant to temperature differences, anti-aging, not easily brittle, provides stable waterproofing in all weather conditions, and is environmentally friendly and recyclable, meeting green building standards and enabling the creation of a comprehensive and long-lasting waterproofing system.
