Color Coated Aluminum Coils

High Hardness Pre-Painted Aluminum Coils are premium-grade aluminum sheets coated with high-durability paint systems (PVDF, FEVE, or Polyester) on a hardened aluminum substrate (e.g., H14, H24, H32 temper). These coils combine exceptional surface hardness (≥2H pencil hardness), weather resistance, and aesthetic versatility, making them ideal for architectural cladding, automotive trim, and high-end appliances.

Galvalume Steel: Protective ceiling with alloy coating
55% aluminum, 43.4% zinc and 1.6% silicon are treated by vacuum magnetron sputtering nano-plating process to form an atomic-level honeycomb-like alloy barrier on the surface of steel! The corrosion resistance is six times that of ordinary galvanized steel (ISO 9227 certification), and the 78% heat reflection rate directly reduces building energy consumption by 30%! Super high-rise curtain walls, standard equipment for new energy vehicle chassis, redefining material life with zero maintenance standards, the ultimate solution for industrial protection!

Galvanized Steel: An AI evolved version of Basic Protection
The AI dynamic temperature control hot-dip galvanizing technology precisely controls the thickness error of the zinc layer within ±0.3μm! 8-25μm dense Zn-Fe alloy layer, no cracks at 180° extreme bending, zero defects at 200A high current welding! From the framework of skyscrapers to agricultural machinery, it achieves military-grade protection at an industrial-grade cost. As the underlying performance pillar of global infrastructure, it truly deserves the title of the king of cost performance!

Aluminum Coil/Pipe/Plate: The speed master of the lightweight revolution
Aviation-grade 7075-T651 aluminum alloy, after three-way forging and double-stage aging, has a strength that directly reaches 620MPa, yet its weight is only one-third of that of steel! A 40μm ceramicized oxide film was rigidly tested in 2200 hours of salt spray, with a thermal conductivity of 195W/m · K! Core materials for maglev tracks and new energy battery boxes, with a 58% weight reduction yet still resistant to extreme loads, leading the lightweight storm of future intelligent manufacturing!

Stainless Steel: The all-round dictator in the high-end field
AOD-VOD double vacuum refining + electroslag remelting reduces the carbon content to 0.008%! 316L has obtained the ISO 10993 medical certification, and 904L has become a god of anti-corrosion in Marine engineering! The nano-mirror surface model has a roughness of Ra≤0.03μm. From precision medical equipment to landmark buildings, with atomic-level purity and ultimate aesthetics, it firmly holds the throne of the hexagonal king in the metal world!

Aluzinc Steel: The Ultimate reducer of cost performance
