DX51D+Z40/80/100/120/180/275 Galvanized Steel Strip and Sheet

X51D+Z galvanized steel is one of the most widely specified grades for hot-dip galvanized steel. DX51D signifies a steel grade for cold forming, specifically defined as “Bending and Profiling Quality.” Its primary characteristic is not high strength, but rather excellent ductility and formability, which are achieved through controlled chemical composition and processing.

Product details

DX51D+Z galvanized steel is one of the most widely specified grades for hot-dip galvanized steel. DX51D signifies a steel grade for cold forming, specifically defined as “Bending and Profiling Quality.”

Its primary characteristic is not high strength, but rather excellent ductility and formability, which are achieved through controlled chemical composition and processing. The ‘+Z’ suffix indicates that the steel substrate is protected by a hot-dip coating of pure zinc, providing effective and reliable corrosion resistance. Combining its dependable formability, robust corrosion protection, and outstanding cost-effectiveness, DX51D+Z serves as a versatile and foundational material across numerous industries.
