DX53D+Z Galvanized Steel Coil

Product Description

DX53D+Z is a hot-dip galvanized steel coil grade designed for applications requiring both good formability and corrosion resistance. The “DX53D” designation indicates a structural steel grade with moderate strength, ideal for cold forming processes such as bending, drawing, and stamping. The “+Z” refers to the zinc coating applied through the galvanizing process, which offers excellent protection against corrosion, making it suitable for outdoor or humid environments. This steel coil is widely used in the automotive, construction, and home appliance industries, where durability and resistance to weathering are crucial. With good weldability, surface finish, and the added benefit of the zinc coating, DX53D+Z steel coils are highly durable and versatile for a variety of manufacturing and engineering applications.

With our careful storage and streamlined operations, you can rely on us to deliver your DX53D+Z Galvanized Steel Coils in excellent condition and on time.

Product Inspection

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.

Product Measurement

DX53D+Z Galvanized Steel Coil meets stringent EN 10346 and ASTM A653 specifications, available in thicknesses of 0.4mm–3.0mm, widths of 700mm–1,650mm, and inner/outer diameters of 508mm–610mm/1,200mm–1,800mm. The zinc coating (Z60–Z275, 60–275g/m²) is verified via XRF (X-ray fluorescence) and magnetic flux testing to ensure uniformity and adhesion strength. Critical parameters like flatness (±1.5 I-units), edge trim tolerance (±1mm), and surface finish (spangle-free or minimized spangle) are inspected using automated optical systems. Mill test certificates (EN 10204 3.1/3.2) validate mechanical properties, including yield strength (140–240MPa), tensile strength (270–400MPa), and elongation (≥26%), making it ideal for automotive stamping, roofing, and appliance manufacturing.

Product Packaging

DX53D+Z Galvanized Steel Coil is precision-packaged to ensure maximum protection against corrosion and mechanical damage during transit and storage. Each coil is tightly wound and secured with rust-resistant steel straps, then encased in multi-layer VCI (Volatile Corrosion Inhibitor) film or waterproof plastic to block moisture, UV rays, and contaminants. Edges are reinforced with protective sleeves to prevent edge crushing, while anti-corrosion oil or desiccant packs are added for shipments to high-humidity regions. Customizable packaging options, including wooden pallets, steel skeleton crates, or slit-to-width bundles, cater to industrial processing needs. Labels with EN 10346 and ASTM A653 compliance, thickness, width, and QR code traceability ensure seamless logistics and compliance with ISO 9001 and global shipping standards.
