ASTM A526 Galvanized Steel Product Information -:- For detailed product information, please contact sales. -: ### **ASTM A526 Galvanized Steel: Commercial Quality Zinc-Coated Sheet** #### **1. Overview** ASTM A526 is a standard specification for **commercial quality** steel sheet, zinc-coated (galvanized) by the hot-dip process. This specification covers requirements for steel sheet in coil and cut lengths, where the primary concern is **corrosion resistance** without the need for severe forming or drawing. It is specifically designed for applications where the steel will be subjected to **moderate bending** or simple forming operations. The standard is widely used in construction and general manufacturing industries. #### **2. Chemical Composition** ASTM A526 does not specify mandatory chemical composition requirements, focusing instead on mechanical properties and coating quality. The base steel is typically a **low-carbon steel** with the following general composition: **Typical Base Metal Chemistry (Commercial Quality):** | Element | Composition (%) | |---------|-----------------| | Carbon (C) | ≤ 0.15 | | Manganese (Mn) | ≤ 0.60 | | Phosphorus (P) | ≤ 0.035 | | Sulfur (S) | ≤ 0.035 | | Silicon (Si) | ≤ 0.030 | **Note:** The actual composition may vary by manufacturer but is controlled to ensure the specified mechanical properties and coating adherence. #### **3. Physical & Mechanical Properties** **Coating Properties:** - **Coating Designations:** G30, G40, G60, G90, G115, G165 (oz/ft²) - **Coating Types:** Regular spangle, minimum spangle, extra-smooth - **Coating Tests:** Bend test, adhesion test per standard requirements **Mechanical Properties:** | Property | Requirement | |----------|-------------| | **Tensile Strength** | 40-55 ksi (275-380 MPa) | | **Yield Strength** | 30-45 ksi (205-310 MPa) | | **Elongation in 2 inches** | 20% minimum | | **Bend Test** | Bend 180° around diameter equal to thickness | **Physical Characteristics:** - **Base Steel Thickness:** 0.023-0.168 inches (0.58-4.27 mm) - **Coating Weight Range:** 0.30-1.65 oz/ft² total both sides - **Surface Finish:** Commercial bright spangled finish standard #### **4. Product Applications** ASTM A526 commercial quality galvanized steel is suitable for applications requiring **moderate formability** and good corrosion resistance: **Construction Applications:** - Roofing and siding panels - Gutters and downspouts - Interior wall panels - Ceiling systems **Industrial Applications:** - Electrical enclosures and cabinets - HVAC ductwork and components - Storage shelving and racks - Industrial containers **Consumer Products:** - Mailboxes and storage boxes - Low-stress structural components - Decorative architectural elements #### **5. International Standards & Equivalents** | Region/Country | Standard | Equivalent Grade | Notes | |----------------|----------|------------------|-------| | **International** | **ISO 3575** | CR4 | Commercial quality hot-dip coated | | **Europe** | **EN 10346** | DX51D+Z | Continuously hot-dip zinc-coated | | **Japan** | **JIS G3302** | SGCC | Hot-dip zinc-coated steel sheet | | **China** | **GB/T 2518** | DX51D+Z | Commercial quality equivalent | **Coating Weight Comparison:** | ASTM A526 | ISO 3575 | Coating Mass (g/m²) | |-----------|----------|-------------------| | G60 | Z180 | 180 | | G90 | Z275 | 275 | | G115 | Z350 | 350 | #### **6. Fabrication Characteristics** **Forming Limitations:** - Suitable for moderate bending and roll forming - Not recommended for severe drawing or stretching - Maximum bend angle: 180 degrees - Minimum bend radius: Equal to sheet thickness **Welding Considerations:** - Can be welded using standard processes - Requires ventilation due to zinc fumes - Coating may be damaged in weld area **Surface Treatment:** - Chemical treatment available for paint adhesion - Chromate conversion coating optional - Suitable for powder coating with proper pretreatment --- **Key Distinction:** ASTM A526 is specifically for **commercial quality** applications, distinguishing it from ASTM A525 which covers multiple quality designations including lock-forming and drawing qualities. This specification is ideal for applications where corrosion resistance is more critical than formability. **Disclaimer:** This information is for reference purposes only.
