Made of high-quality aluminum alloy, processed through precision extrusion, polishing and surface treatment, the profiles are regular, smooth and dimensionally accurate (deviation ≤±0.5mm). Core advantages: lightweight (density only 1/3 of steel), reducing building load and facilitating construction; high strength (tensile strength ≥150MPa), suitable for stress-bearing components; excellent corrosion resistance, with service life of 20-30 years outdoors and low maintenance cost after fluorocarbon spraying, anodizing and other treatments.
