Prepainted RAL9016 steel Aluminum in Coils

Applicable Scenarios for Materials such as Aluminized Steel, Color-Coated Steel, Galvanized Steel, and Aluminum Plates Galvanized Steel Advantages: Low cost, easy to process, and the zinc coating provides sacrificial anode protection. Applications:Dry inland environments, general industrial plants, commercial buildings (corrosion classes C1–C2), and short-term projects (10–15 year lifespan). Limitations: Prone to corrosion in environments with humidity >85% or containing chlorine/sulfur; not recommended for coastal or chemical industrial zones. Aluminized-Zinc Steel (e.g., 55% Al-Zn) Advantages: Corrosion resistance is 3–5 times greater than that of galvanized steel; lifespan can exceed 20 years (in C3 environments); features high thermal reflectivity and high-temperature resistance (stable up to 315°C). Applications: Coastal areas not directly exposed to salt spray, electronics manufacturing plants, food processing facilities, subway stations, and roofing materials. Limitations: Cut edges require protective treatment; bending radius must be ≥1.5 times the sheet thickness. Aluminum Plates (e.g., 5052 Series) Advantages: Density is only one-third that of steel; offers excellent thermal conductivity; naturally forms a protective Al₂O₃ oxide film; resistant to moisture-induced corrosion. Applications: Vehicle-mounted and marine air conditioning systems, high-rise buildings (for weight reduction), and temporary/demountable structures.
