EN 10142/10143 DX51D+Z275 Hot Dip Galvanized Steel Coil
Zinc Coated Steel coils
DX51D+Z275 is a low carbon steel sheet that has been hot-dip galvanized with a zinc coating weighing 275 grams per square meter, meeting European standards for flat products. (it equivalently to ASTM A653 G90)
EN 10142/10143
EN 10142/10143 is a European standard that specifies the requirements for continuously hot-dip zinc-coated low carbon steel flat products for cold forming. The standard includes several parts, each focusing on specific aspects of the production, testing, and performance of galvanized steel products.
DX51D+Z
DX51D+Z is a designation or grade of low carbon steel that has been hot-dip galvanized with a coating of zinc. The “DX” prefix indicates that the steel is of commercial quality, while the “51” refers to the minimum yield strength in ksi (kilopounds per square inch) of 51. The “D” stands for drawing quality, indicating that the steel is suitable for use in drawing applications, such as forming into shapes or profiles. The “+Z” suffix indicates that the steel has been galvanized with a zinc coating, and the “Z” stands for the zinc coating itself.

Applications
Galvanized steel sheets with a high zinc coating (275 g/m²) are suitable for a wide range of applications due to their excellent corrosion resistance. These sheets are commonly used in outdoor environments and applications that require high durability, such as roofing, cladding, and fencing. They are also frequently used in the construction industry for structural components, including beams, columns, and purlins. Additionally, galvanized steel sheets with a high zinc coating are used in the manufacturing of HVAC ducts, appliances, and automotive parts. The high zinc coating provides long-term protection against rust and corrosion, making these sheets a reliable and cost-effective option for many different applications.
