DX51D+Z/DC51D+Z Galvanized Coil/Strip

DX51D+Z and DC51D+Z are essentially the same type of hot-dip galvanized product (the designations differ only due to different standards). They are essentially coils/strips with a “cold-rolled base plate and continuous hot-dip galvanized layer,” making them one of the most widely used basic galvanized products in industry.

Both are continuous hot-dip galvanized steel coils/strips, with the “+Z” designation clearly indicating hot-dip galvanizing. The differences stem primarily from regional standardization systems:
DX51D+Z complies with EU standard EN 10346 and is a common designation in the European and international markets.
DC51D+Z complies with Chinese national standard GB/T 2518 and is the mainstream designation for domestic production and procurement.

The two products share highly consistent technical parameters (such as base plate material and zinc coating requirements) and can be considered “same product with different names” and are interchangeable in practical applications.
