• Enhanced protection: The coating thickness reaches 60-120μm, effectively isolating air, moisture, and corrosive substances (such as acid rain and industrial fumes), significantly extending the service life of the drainage system.

• Personalized decoration: Supports full-colour customization according to RAL colour standards or building design requirements. Whether it is matching the main tone of the building facade, echoing the surrounding natural environment, or creating a unique visual focal point, it can achieve a natural and coordinated effect, improving the overall aesthetic value of the building.

• Environmental friendliness: No volatile organic compounds (VOCs) are released during the coating process, complying with global environmental protection standards and meeting the development needs of green buildings.

• Production efficiency: The automated production line can achieve a daily output of thousands of square meters, significantly shortening the delivery cycle and meeting the tight construction schedules of large-scale buildings.

• Surface consistency: The roller coating process ensures uniform film thickness, smooth surface, and no obvious flaws such as bubbles or unevenness. The colour difference between batches is controlled within ±ΔE 1.5, ensuring the consistency of the building’s external appearance.

• Wear resistance: The roller coating layer has high hardness (≥3H), which can resist scratches during transportation and installation, maintaining the integrity of the surface effect.

• Leakage prevention: The one-piece seamless structure eliminates the risk of water leakage at welding seams or joints, which is a common problem in traditional steel or plastic drainage pipes. Even under extreme weather conditions such as heavy rain and strong winds, it can ensure stable operation without leakage.

• Deformation resistance: Aluminium alloy has excellent mechanical properties, with a tensile strength of ≥240MPa and yield strength of ≥200MPa. It is not easy to deform under the action of external forces such as gravity, wind load, or temperature changes, maintaining the structural integrity of the pipeline.

• Cost-effectiveness: Although the initial investment is slightly higher than that of plastic pipes, the service life of seamless aluminium pipes can reach 30-50 years (3-5 times that of plastic pipes), and there is no need for frequent maintenance and replacement, reducing the total life-cycle cost of the building.

• Anti-oxidation and anti-rust: The surface of coloured aluminium drainage systems is treated with a special oil-resistant antioxidant layer, and the aluminium substrate itself forms a dense oxide film (Al₂O₃) in the air, which can effectively resist corrosion from moisture, salt spray, and chemical substances. It is suitable for various harsh environments such as coastal areas, industrial zones, and high-humidity regions.

• Fade resistance: The high-quality coating (powder coating or roller coating) has excellent UV resistance, with a colour retention rate of ≥90% after 10 years of outdoor use. It can resist the fading and discolouration caused by long-term exposure to sunlight, maintaining a bright and pure colour.

• Economical and flexible processing: They can be cut, bent, and punched according to the actual needs of the construction site, with low processing costs and high efficiency. The edge nibbling effect ensures the flatness of the pipe ends, facilitating connection and installation.

• Universal elbow matching: The system integrates any angle elbows, S-shaped elbows, and waistline bends, which can adapt to complex building structures (such as sloping roofs, curved facades, and overhanging eaves). The precise fit of the elbows ensures the smoothness of the water flow and the reliability of the installation, avoiding water accumulation and noise caused by improper pipe connection.

• Factory customization: Supports personalized design and production according to the architectural drawings and on-site conditions. Whether it is special pipe diameters, non-standard elbows, or integrated drainage components, it can be customized in the factory to ensure the accuracy and compatibility of the products.

• On-site problem-solving: The professional technical team provides on-site guidance and technical support, and can quickly adjust and customize accessories according to the special requirements of the installation site (such as sudden structural changes, space constraints, etc.), ensuring the smooth progress of the construction.
