ASTM A525M Galvanized Steel Product Information -:- For detailed product information, please contact sales. -: ### **ASTM A525M Galvanized Steel: Metric Specification for Zinc-Coated Sheet by Hot-Dip Process** #### **1. Overview** ASTM A525M is the metric companion standard to ASTM A525, specifying requirements for steel sheet, zinc-coated (galvanized) by the hot-dip process in coil and cut lengths. This metric specification covers commercial qualities and designations with all measurements and requirements expressed in SI (International System) units. The standard provides a comprehensive framework for zinc-coated sheets used in applications requiring corrosion protection, with specific requirements for coating mass, mechanical properties, and dimensional characteristics in metric terms. #### **2. Chemical Composition** As with its imperial counterpart, ASTM A525M focuses on coating properties and mechanical performance rather than mandating specific chemical compositions. The base steel typically conforms to commercial quality designations with the following general characteristics: **Base Steel Types (Metric Equivalent):** - **Commercial Quality (CQ):** Maximum 0.15% carbon content - **Lockforming Quality (LFQ):** Enhanced formability for severe deformation - **Drawing Quality (DQ):** Suitable for moderate drawing operations - **Structural Quality (SQ):** Meets metric structural steel requirements **Typical Base Metal Chemistry Range:** | Element | Composition (%) | |---------|-----------------| | Carbon (C) | ≤ 0.15 | | Manganese (Mn) | ≤ 0.60 | | Phosphorus (P) | ≤ 0.035 | | Sulfur (S) | ≤ 0.035 | | Silicon (Si) | ≤ 0.030 | #### **3. Physical & Mechanical Properties** **Coating Properties (Metric):** - **Coating Designations:** Z180, Z275, Z350, Z450, Z600 (g/m²) - **Coating Types:** Regular spangle, minimum spangle, extra-smooth, skin-passed - **Coating Mass Range:** 180-600 g/m² total mass both sides **Mechanical Properties (Metric Units):** | Property | Commercial Quality | Drawing Quality | Structural Quality | |----------|-------------------|-----------------|-------------------| | **Tensile Strength** | 270-380 MPa | 270-340 MPa | 310-450 MPa | | **Yield Strength** | 205-310 MPa | 170-275 MPa | 250-345 MPa | | **Elongation (50 mm)** | 20-30% | 25-35% | 15-25% | | **Hardness (HRB)** | 45-65 | 40-60 | 50-70 | **Physical Characteristics:** - **Density:** 7,850 kg/m³ - **Coating Thickness:** 25-85 μm per side (depending on coating designation) - **Surface Treatment:** Chromate conversion coating or phosphate treatment #### **4. Product Applications** ASTM A525M galvanized steel is widely used in international markets and metric-based industries: **Construction & Infrastructure:** - **Architectural Applications:** Roofing (0.4-0.8 mm thickness), wall cladding, and rainwater systems - **Structural Components:** Light gauge steel framing, purlins, and trusses - **Building Services:** HVAC ductwork, electrical conduits, and cable trays **Transportation & Automotive:** - **Vehicle Components:** Body panels, chassis parts, and structural reinforcements - **Commercial Vehicles:** Truck body panels, trailer components, and container parts **Industrial & Manufacturing:** - **Equipment Manufacturing:** Agricultural machinery, material handling equipment - **Electrical Enclosures:** Switchgear cabinets, control boxes, and distribution panels - **Consumer Goods:** Appliance housings, furniture frames, and storage systems #### **5. International Standards & Equivalents** **Direct Metric Equivalents:** | Region/Country | Standard | Equivalent Designation | |----------------|----------|---------------------| | **International** | **ISO 3575** | Commercial Quality HDZ | | **Europe** | **EN 10346** | DX51D+Z | | **Japan** | **JIS G3302** | SGCC | | **China** | **GB/T 2518** | DX51D+Z | | **Australia** | **AS 1397** | G550-Z275 | **Coating Mass Equivalents:** | ASTM A525M | ISO 3575 | EN 10346 | Typical Application | |-----------|----------|----------|-------------------| | Z180 | Z180 | Z180 | Interior applications | | Z275 | Z275 | Z275 | General construction | | Z350 | Z350 | Z350 | Automotive exterior | | Z450 | Z450 | Z450 | Severe environments | | Z600 | Z600 | Z600 | Heavy corrosion resistance | #### **6. Fabrication & Processing Characteristics** **Forming & Manufacturing:** - **Bending:** Minimum bend radius of 1t (where t = sheet thickness) - **Punching:** Suitable for blanking and piercing operations - **Joining:** Compatible with welding, riveting, and adhesive bonding **Surface Treatment Compatibility:** - **Pre-treatment:** Phosphating and chromating for enhanced paint adhesion - **Painting:** Suitable for both liquid and powder coating systems - **Printing:** Can be printed using standard industrial processes **Quality Assurance Requirements:** - **Coating Mass Verification:** By weighing or magnetic thickness gauge - **Adhesion Testing:** Bend test per ASTM E290 - **Surface Quality:** Visual inspection per ASTM A754 --- **Note:** ASTM A525M is the metric equivalent of ASTM A525 and contains the same technical requirements expressed in SI units. The specification is particularly important for international projects and countries using the metric system. Always consult the latest version of the standard for specific project requirements and verify material certifications for critical applications. -:- For detailed product information, please contact sales. -: ASTM A525M Galvanized Steel Specification Dimensions Size： Diameter 20-1000 mm Length <4420 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 A525M Galvanized Steel Properties -:- For detailed product information, please contact sales. -:
