Galvalume sheet specification refers to the specific technical characteristics and standards that define a galvalume steel sheet. Galvalume, also known as zinc-aluminum alloy coated steel, combines the corrosion resistance of aluminum with the galvanic protection of zinc to provide superior protection compared to galvanized steel.
Key Specifications
- Base Metal: Typically cold-rolled steel, with various grades available (e.g., commercial steel, structural steel).
- Coating Composition: Approximately 55% aluminum, 43.4% zinc, and 1.6% silicon by weight.
- Coating Weight: Measured in grams per square meter (g/m²) or ounces per square foot (oz/ft²). Common coating weights include AZ50 (50 g/m² total both sides), AZ100, AZ150, and AZ180. Higher numbers indicate heavier coatings and greater corrosion resistance.
- Sheet Thickness: Varies depending on the application, typically ranging from 0.3mm to 1.2mm.
- Sheet Width: Standard widths are available, but custom widths can often be produced.
- Surface Treatment: Can include chromate passivation, oiling, or acrylic coating to further enhance corrosion resistance and provide a suitable surface for painting.
- Standards: Conforms to various international standards such as ASTM A792 (US), EN 10346 (Europe), and JIS G3321 (Japan).
Factors to Consider
- Application: The intended use of the galvalume sheet will influence the required coating weight, thickness, and steel grade.
- Environment: Exposure to harsh environments (e.g., coastal areas, industrial zones) necessitates higher coating weights.
- Forming Requirements: The ductility and formability of the steel should be considered if the sheet will be subjected to bending, stamping, or other forming operations.
