Product Advantages

core advantages:

Advantage	Detailed description
Lightweight and strong	The density is only 1/3 of steel, and the tensile strength is ≥ 110 MPa, which reduces the roof load and adapts to complex building structures.
Excellent corrosion resistance	Natural oxide film coating double protection, resistant to rain, salt spray and snow melting agent erosion, service life of more than 25 years.
Quick installation	The pre-coating process eliminates the need for on-site spraying, supports roll forming or segmented cutting, and increases construction efficiency by 40%.
Aesthetic fit	The custom color is in harmony with the building façade, avoiding the industrial feel of traditional metal drainage channels and improving the overall design quality.
Environmentally sustainable	It is 100% recyclable, and the production energy consumption is 50% lower than that of galvanized steel, which is in line with the carbon neutrality goal of the European Union's Green Deal.

Application scenarios and typical cases:
1. Residential and commercial building drainage systems
Uses: roof gutters, rainwater diversion pipes, cornice decoration.

Case:

Project: Vancouver, Canada, "Passive House" energy-efficient residential community.

Solution: White matte coated aluminum coil for roof drainage system, combined with solar panel design.

Achievement:

Resistant to high precipitation (average annual rainfall of 1450mm), drainage efficiency increased by 30%.

Passed PHIUS (Passive House) certification, with an annual energy saving of 15%.

2. Restoration of historic buildings
Uses: renovation of roof drainage channels of ancient buildings, water diversion system of church spires.

Case:

Project: Restoration of St. Paul's Cathedral in London, UK.

Solution: Imitation bronze PVDF coated aluminum coil to replace the original rusted copper drainage gutter.

Achievement:

The appearance retains the historical texture, the cost is reduced by 60%, and the life is extended to 50 years.

Awarded the British Heritage Award.

3. Application in extreme climate areas
Uses: anti-freeze drainage system in alpine areas, coastal anti-salt spray corrosion guide trough.

Case:

Project: Hotel in the Arctic Circle in Tromsø, Norway.

Solution: 0.8mm aluminum coil with anti-freeze coating, suitable for -30°C extreme cold environment.

Achievement:

Resistant to ice impact, no deformation or cracking of the drain groove, and extended maintenance intervals up to 10 years.

4. Industrial & Utilities
Uses: Factory roof drainage, airport canopy water conduction, stadium roof rainwater management.

Case:

Project: Park Stadium, Sydney, Australia.

Solution: Custom dark grey aluminum coil for giant ceiling drainage system.

Achievement:

Resistant to ultraviolet rays and strong winds (wind speed ≥ 120km/h), according to AS/NZS 1562.1 standard.

The lightweight design reduces the load on the steel structure and saves 20% of the cost.

International Standards & Compliance
Performance Testing:

Salt Spray Test: ASTM B117 (> 4000 hours non-corrosive).

Weathering test: ISO 4892-3 (UV aging).

Environmental Certifications:

Cradle to Cradle® Silver (Material Health).

EPD Environmental Product Declaration (Carbon Footprint Transparency).

Future Trends & Innovations:
Intelligent drainage system: integrated sensors to monitor water flow and blockage, linked to the building management system (BMS).

Superhydrophobic coating: Developed a lotus leaf-like surface coating to reduce dirt adhesion and cleaning frequency.

Recycled aluminium process: 80% recycled aluminium raw material is used, reducing carbon footprint by 40%.
