ASTM A525 Galvanized Steel Product Information -:- For detailed product information, please contact sales. -: ### **ASTM A525 Galvanized Steel: Commercial Quality Zinc-Coated Sheet** #### **1. Overview** ASTM A525 is a standard specification for steel sheet, zinc-coated (galvanized) by the hot-dip process, in coil and cut lengths. This specification covers various commercial qualities and designations intended for applications where corrosion resistance is required. The standard includes multiple coating designations, surface treatments, and surface finishes to meet diverse application requirements. The zinc coating provides sacrificial protection to the base steel, making it suitable for exposed applications where corrosion resistance is essential. #### **2. Chemical Composition** ASTM A525 does not specify mandatory chemical composition requirements, as it focuses primarily on the coating properties and mechanical properties of the base steel. However, the base steel typically conforms to one of the following specifications: **Base Steel Types:** - **Commercial Quality (CQ):** Typically low carbon steel with maximum 0.15% carbon - **Lockforming Quality (LFQ):** Suitable for severe deformation applications - **Drawing Quality (DQ):** For moderate drawing applications - **Structural Quality (SQ):** Meets ASTM A36 or similar chemistry requirements **Typical Base Metal Chemistry (Commercial Quality):** | Element | Composition (%) | |---------|-----------------| | Carbon (C) | ≤ 0.15 | | Manganese (Mn) | ≤ 0.60 | | Phosphorus (P) | ≤ 0.035 | | Sulfur (S) | ≤ 0.035 | #### **3. Physical & Mechanical Properties** **Coating Properties:** - **Coating Designations:** G30, G40, G60, G90, G115, G165 (oz/ft²) - **Coating Types:** Regular spangle, minimum spangle, extra-smooth, skin-passed - **Coating Structure:** Iron-zinc alloy layers with pure zinc overlay **Mechanical Properties (Vary by quality designation):** | Property | Commercial Quality | Drawing Quality | Structural Quality | |----------|-------------------|-----------------|-------------------| | **Tensile Strength** | 40-55 ksi | 40-50 ksi | 45-65 ksi | | **Yield Strength** | 30-45 ksi | 25-40 ksi | 36-50 ksi | | **Elongation** | 20-30% | 25-35% | 15-25% | **Physical Characteristics:** - **Coating Weight:** 0.30-1.65 oz/ft² (G30-G165) - **Surface Finish:** Regular spangle, minimized spangle, or smooth finish - **Surface Treatment:** Chemical treatment chromate or phosphate #### **4. Product Applications** ASTM A525 galvanized steel finds applications across numerous industries due to its excellent corrosion resistance and formability: **Construction & Building:** - Roofing and siding panels - Gutters and downspouts - Structural framing members - HVAC ductwork and components **Automotive & Transportation:** - Body panels and structural components - Truck and trailer parts - Underbody components **Industrial & Manufacturing:** - Electrical enclosures and cabinets - Agricultural equipment components - Storage tanks and containers - Appliance housings **Consumer Products:** - Outdoor furniture - Mailboxes and storage boxes - Playground equipment #### **5. International Standards & Equivalents** | Region/Country | Standard | Equivalent Grade | Notes | |----------------|----------|------------------|-------| | **International** | **ISO 3575** | Commercial Quality | Hot-dip zinc-coated steel | | **Europe** | **EN 10346** | DX51D+Z | Continuously hot-dip zinc-coated steel | | **Japan** | **JIS G3302** | SGCC | Hot-dip zinc-coated steel sheet | | **China** | **GB/T 2518** | DX51D+Z | Similar coating designations | | **Germany** | **DIN EN 10346** | DX51D+Z | European standard implementation | **Coating Weight Equivalents:** | ASTM A525 | ISO 3575 | EN 10346 | Typical Coating (g/m²) | |-----------|----------|----------|---------------------| | G60 | Z180 | Z180 | 180 | | G90 | Z275 | Z275 | 275 | | G115 | Z350 | Z350 | 350 | #### **6. Fabrication & Processing** **Forming Considerations:** - Excellent formability for bending and roll-forming - Coating may flake in severe deformation areas - Recommended to use proper die clearances and radii **Welding:** - Can be welded using standard processes (GMAW, GTAW, Resistance) - Requires proper ventilation due to zinc fumes - May require coating removal in weld areas for critical applications **Painting & Finishing:** - Chemical treatment required for paint adhesion - Suitable for powder coating and liquid paint systems - Chromate treatments provide enhanced corrosion protection --- **Disclaimer:** This information is for reference purposes only. For specific applications, consult the latest ASTM A525 standard and qualified materials engineers. Coating properties and mechanical characteristics may vary by manufacturer and processing parameters. -:- For detailed product information, please contact sales. -: ASTM A525 Galvanized Steel Specification Dimensions Size： Diameter 20-1000 mm Length <4419 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: ASTM A525 Galvanized Steel Properties -:- For detailed product information, please contact sales. -:
