As a global aluminum products manufacturer, Haomei Aluminum’s gold anodised aluminum sheets, specially designed for harsh outdoor environments, feature a 10μm+ thickened oxide film and high weather resistance, making them a preferred material for high-end outdoor decoration. Our process control and supply advantages provide customers with stable delivery and cost-effective options.
Specification of Gold Anodised Aluminium Sheet For Outdoor Use:
The base alloys are primarily 1060/1070 pure aluminum and 5052/5005 rust-resistant aluminum, with high-strength alloys such as 6061 available upon request.
Thicknesses range from 1.0-3.0mm, a mainstream specification for outdoor curtain walls, while also covering the full range from 0.3-6.0mm to meet the structural requirements of various outdoor scenarios.
Standard widths are 1000/1250/1500mm, with corresponding lengths of 2440/3000mm, but can be cut to size as needed, with a maximum width of 1550mm.
The surface treatment employs an outdoor-specific gold anodizing process, offering both brushed and mirror finishes.
The oxide film thickness is controlled between 10-25μm with stringent tolerances: thickness ±0.05mm, width ±0.2mm (precision grade reaches ±0.02mm).
The surface hardness reaches Mohs 9, comparable to gemstone hardness, suitable for long-term outdoor use.
Core Features: Performance matrix designed specifically for outdoor uses
– Superior Weather Resistance:
The 10μm thickened oxide film withstands 3000 hours of salt spray testing, boasts a 99% UV shielding rate, maintains stable performance under extreme temperature variations from -40℃ to 80℃, and will not fade or corrode for 20 years.
– Ultimate Metallic Texture:
Retains the original metallic luster of aluminum, combined with brushed/mirror finishes, presenting a delicate gradient from champagne gold to titanium gold. Color uniformity ΔE<1.5, far superior to spray coating processes.
– Lightweight and High-Strength:
With a density of only 2.7g/cm³, it is 70% lighter than traditional steel while maintaining the tensile strength of 5052 alloy (≥180MPa). It is easy to install and structurally safe.
– Zero-Maintenance:
The dense oxide film on the surface has strong self-cleaning properties; rainwater can easily restore its cleanliness, eliminating the need for regular repainting and cleaning, significantly reducing later maintenance costs.
Production Process: Quality Assurance Through Full-Process Autonomous Control
Haomei adopts a five-stage full-process technology: Wire Drawing – Anodizing – Coloring – Sealing – Inspection, with each step being independently controllable:
– Precision Wire Drawing:
Imported equipment is used to create a uniform texture, with a depth controlled between 5-15μm to ensure surface consistency.
– Anodizing:
A dense oxide film is generated by passing electricity through an acidic electrolyte, with a thickness precisely controlled between 10-25μm, providing a robust protective layer for outdoor use.
– Environmentally Friendly Coloring:
Utilizing inorganic pigment adsorption technology, the color saturation is high and lightfastness is strong, complying with EU REACH standards.
– Medium-Temperature Sealing:
Sealing treatment at 60-80℃ completely seals oxide film pores, improving corrosion resistance and color stability.
– Full Inspection Before Shipment:
Each batch undergoes four core tests: color difference, hardness, salt spray, and weather resistance, providing a complete quality inspection report.
Quality and Price Advantages: Core Competitive Advantages in Global Markets
– Quality Strength:
Certified by ISO9001, CE, RoHS, and other international standards. Products pass ASTM G154 ultraviolet testing, with color difference variation ΔE<3 and gloss retention exceeding 85%, meeting global high-end project standards.
– Cost Optimization Solutions:
Full Industry Chain Layout: From aluminum ingot procurement to finished product shipment, reducing intermediate links, costs are 8-12% lower than the industry average.
Economies of Scale: Annual production capacity of 50,000 tons, bulk purchasing reduces raw material costs, supporting both small-batch customization and large-volume orders.
Logistics Optimization: Partnering with leading global logistics providers, we offer door-to-door service, with delivery times for North America/Middle East routes 3-5 days faster than the industry average.
Export Service Upgrade: We offer multiple trade terms including FOB/CIF/EXW, support USD pricing and letter of credit settlement, and have a multilingual sales team providing technical parameter integration, installation guidance, and after-sales support.
