DX51D+Z Galvanized Steel Coil

DX51D+Z galvanized steel coil is a widely used steel product, characterized by its excellent formability, corrosion resistance, and moderate strength. The “DX51D” grade refers to a cold-rolled steel with good mechanical properties suitable for general-purpose applications, while the “+Z” indicates a layer of zinc coating, applied through the hot-dip galvanizing process, which enhances the steel’s ability to resist rust and wear. Typically, the zinc coating thickness ranges from 60 g/m² to 275 g/m², providing long-lasting protection against environmental elements. This galvanized steel coil is commonly used in industries such as construction, automotive, home appliances, and manufacturing, offering durability, ease of processing, and improved performance in harsh environments.

Our warehouse facilities are designed to securely store DX51D+Z Galvanized Steel Coils, ensuring they are protected from environmental factors and easily accessible for efficient order fulfillment. The warehouse is carefully organized, with dedicated storage spaces for different coil sizes and specifications, ensuring smooth inventory management. To maintain the quality of the galvanized coating, the warehouse environment is climate-controlled, minimizing exposure to moisture and temperature fluctuations. Our advanced inventory management system enables accurate tracking and ensures quick access to products for timely delivery. Whether you’re ordering large quantities or specific coil sizes, our DX51D+Z Galvanized Steel Coils are securely stored and ready for prompt dispatch to meet your project deadlines.Facilities utilize vertical coil storage racks with ​non-metallic separators to avoid edge damage, supported by ​20-ton overhead cranes and automated coil turners for efficient handling. Real-time inventory management via ​RFID and barcode scanning ensures ​99.9% stock accuracy and rapid order fulfillment. Anti-corrosion protocols, including desiccant systems and epoxy-coated flooring, align with ​ASTM A123 standards. Partnering with global 3PL providers, we guarantee ​FOB/CIF shipments within 10–18 days, with ​24/7 digital tracking and ​JIT (Just-in-Time) delivery options tailored to construction, HVAC, and agricultural sectors.

The appearance of the coating is bright, meticulous, without sagging or wrinkles. Thickness inspection can use coating thickness gauge, the method is relatively simple. The thickness of the coating can also be obtained by converting the amount of zinc adhesion. For the bonding strength, a bending press can be used to bend the sample at 90-180°, and there should be no cracks or peeling of the coating. A heavy hammer can also be used to test, and the salt spray test and copper sulfate corrosion test can be done in batches.

Our DX51D+Z Galvanized Steel Coils are manufactured to precise measurements to meet the highest industry standards. Available in various thicknesses, widths, and coil diameters, our steel coils are ideal for a wide range of applications, from construction to automotive manufacturing. The DX51D+Z grade provides excellent mechanical strength, making it highly durable and resistant to corrosion. During the production process, each coil undergoes rigorous measurement controls to ensure consistent thickness, width, and coil diameter, ensuring uniformity across every batch. Whether you require standard sizes or custom specifications, our DX51D+Z Galvanized Steel Coils provide reliable and high-quality performance for your projects.

DX51D+Z Galvanized Steel Coil meets ​EN 10346 and ​ASTM A653 specifications, available in:

• ​Thickness: 0.3mm–3.0mm
• ​Width: 600mm–1,650mm
• ​Inner/Outer Diameter: 508mm–610mm (ID) / 1,000mm–1,800mm (OD).
  The zinc coating (60–275g/m², Z60–Z275) is verified via ​XRF (X-ray fluorescence) and ​magnetic flux gauges to ensure uniformity and adhesion strength. Critical tolerances include:
• ​Flatness: ±2 I-units
• ​Edge Trim: ≤1mm deviation
• ​Surface Finish: Spangle-free or minimized spangle for aesthetic applications.
  Mechanical properties, validated by ​EN 10204 3.1/3.2 mill certificates:
• ​Yield Strength: 140–220MPa
• ​Tensile Strength: 270–420MPa
• ​Elongation: ≥26% (ideal for roll-forming, roofing, and light structural applications).

DX51D+Z Galvanized Steel Coil is meticulously packaged to ensure corrosion resistance and structural protection during global logistics. Each coil is tightly wound and secured with rust-resistant steel straps, then wrapped in multi-layer ​VCI (Volatile Corrosion Inhibitor) film or ​waterproof plastic to block moisture, UV exposure, and physical abrasion. Edges are reinforced with steel or plastic guards to prevent crushing during transit. For long-term storage or high-humidity regions, anti-corrosion oil or desiccant packs are added. Custom packaging options, including ​wooden pallets, ​steel skeleton crates, or slit-to-width bundles, are available for industrial processing needs. Labels with grade (DX51D+Z), thickness, width, zinc coating weight (Z60–Z275), and QR code traceability comply with ​EN 10346 and ​ISO 9001 standards for seamless global shipping.With our superior packaging methods, your DX51D+Z Galvanized Steel Coils will arrive in perfect condition, ready for immediate use in your operations.
