Products FAQ
What galvanized coating weights are available for DX51D galvanized steel coils?
Common galvanized coating weight options include Z60, Z80, Z100, Z120, Z180, Z200, and Z275 (in g/m²). The higher the galvanized coating weight, the longer the corrosion protection lifespan.
What does DX51D+Z275 mean?
DX51D+Z275 indicates that the base material is DX51D, with a hot-dip galvanized coating of pure zinc, and a total coating weight of 275 g/m² on both sides. Here, “Z” stands for the hot-dip galvanizing process using pure zinc, and “275” is the nominal total coating weight.
What is DX51D galvanized steel coil?
DX51D galvanized steel coils are hot-dip galvanized steel coils that comply with the European EN 10346 standard. They are high-quality cold-formed galvanized steel with excellent surface finish, stable zinc coating adhesion, good ductility, and outstanding corrosion resistance. They are widely used in civil construction, manufacturing, and industrial processing sectors worldwide.
We supply DX51D+Z/ZF/ZA/AZ/ZM galvanized coils in a full range of specifications, with zinc coating weight grades ranging from Z80 to Z275. We strictly control the uniformity of the zinc coating thickness, surface flatness, and internal grain structure to effectively prevent oxidation, rust, coating peeling, and structural deformation during processing and use. Every batch of products undergoes 100% quality inspection, including surface defect detection, zinc coating thickness measurement, dimensional calibration, and mechanical property verification. We support custom processing, provide complete inspection certificates, and have global cross-border delivery capabilities, fully meeting the large-scale procurement and high-standard processing needs of the industrial and construction sectors both domestically and internationally.
