DX51D+Z Galvanized Steel Strip
Product Description
DX51D+Z is a grade of galvanized steel strip commonly used in manufacturing processes that require good formability and corrosion resistance. The “DX51D” designation indicates that the steel has a moderate tensile strength and is suitable for cold-formed applications, while the “+Z” signifies that the steel has been coated with a layer of zinc for enhanced protection against rust and environmental degradation. This zinc coating helps extend the lifespan of the material, making it ideal for use in applications like automotive components, roofing, appliances, and general fabrication. The DX51D+Z steel strip offers a balance of strength, workability, and durability, making it a preferred choice for industries requiring both structural integrity and long-term protection against corrosion.

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
Engineered to EN 10346 standards, DX51D+Z Galvanized Steel Strip offers a thickness range of 0.2–1.2 mm (±0.02 mm tolerance), widths of 20–250 mm, and zinc coating classes (Z60–Z100) for non-structural applications like temporary fencing, greenhouse frames, and DIY crafts. Tensile strength spans 240–320 MPa, with elongation up to 18% for simple bending. Custom slit widths and coil weights (0.5–5 tons) optimize material usage for small-scale production.
Product Packaging
Our DX51D+Z Galvanized Steel Strip is securely packaged in heavy-duty, UV-resistant polypropylene sleeves with reinforced edge guards to ensure safe transit for lightweight applications. Each coil is shrink-wrapped in anti-corrosion film and strapped with steel bands, preserving zinc coating integrity during global logistics. Bulk orders (2,000+ coils) include palletized packaging with customizable branding or eco-friendly recyclable materials to meet ESG goals.
