DX54D+Z Galvanized Steel Coil

DX54D+Z is a hot-dip galvanized steel coil designed for applications that require excellent formability and corrosion resistance. The “DX54D” grade indicates a steel with moderate strength, suitable for cold working processes such as bending, stamping, and drawing. The “+Z” signifies a zinc coating applied through the galvanizing process, which provides an effective barrier against corrosion and enhances the steel’s durability, especially in outdoor or harsh environments. DX54D+Z coils are commonly used in industries such as automotive, construction, and appliances, where both strength and long-term resistance to weathering are critical. The steel offers good weldability, smooth surface quality, and excellent protection from corrosion, making it ideal for components exposed to moisture and atmospheric conditions.

Our modern warehouse is fully equipped to handle the safe storage and efficient management of DX54D+Z Galvanized Steel Coils. The coils are organized by type, thickness, and size, allowing for quick retrieval and fast order processing. To maintain the quality of the galvanized coating, our climate-controlled warehouse ensures that the coils are protected from extreme temperatures and moisture. With an advanced inventory management system in place, we can easily track stock levels and ensure timely fulfillment of orders. This well-organized system guarantees that your DX54D+Z Galvanized Steel Coils will be delivered promptly and in pristine condition, ready for your project’s needs.

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.

DX54D+Z Galvanized Steel Coil adheres to strict tolerances per EN 10346 and ASTM A653, available in thicknesses of 0.3mm–3.0mm, widths of 600mm–1,800mm, and inner/outer diameters of 508–610mm/1,000–1,800mm. The zinc coating (Z60–Z275, 60–275g/m²) is verified via XRF (X-ray fluorescence) and magnetic thickness gauges, ensuring uniform adherence for enhanced durability. Critical properties like flatness (±2 I-units), edge trim tolerances (≤1mm), and surface finish (minimal spangle or spangle-free) are inspected using automated optical systems. Mill test certificates (EN 10204 3.1/3.2) validate mechanical properties, including yield strength (140–260MPa), tensile strength (270–420MPa), and elongation (≥24%), optimized for automotive stamping, roofing, and appliance manufacturing.

DX54D+Z Galvanized Steel Coil is expertly packaged to ensure corrosion resistance and structural integrity during global logistics. Each coil is tightly wound and secured with rust-resistant steel straps, then encased in multi-layer protective materials—including VCI (Volatile Corrosion Inhibitor) film, waterproof plastic, or coated kraft paper—to block moisture, UV exposure, and physical abrasion. Edges are reinforced with steel or plastic guards to prevent crushing, while anti-corrosion oil or desiccant packs are added for long-term storage in humid climates. Custom packaging options, such as wooden pallets, steel skeleton crates, or slit-to-width bundles, cater to industrial processing needs. Labels with ASTM A653, EN 10346 compliance, thickness, width, and QR code traceability are applied, meeting ISO 9001 and international freight standards.
