DX51D galvanized sheet material is a non-ferrous alloy mainly composed of zinc as the matrix and other elements. The main alloy elements are aluminum, copper, magnesium, etc. Zinc alloy has low melting point, good fluidity, easy plastic processing and welding, and is resistant to atmospheric corrosion. According to the manufacturing process, it can be divided into cast zinc alloy and deformed zinc alloy. The commonly used cast zinc alloy is zinc aluminum copper magnesium alloy. Its casting process performance is good, and the cooling rate has little impact on the mechanical properties. It is mainly used to manufacture mechanical parts, toys, decorations, household appliances, etc.

Galvanizing is a zinc coating applied to sheets of steel through a process called “continuous hot-dip,” in which steel sheet passes through a bath of molten zinc. The liquid zinc bonds to the iron in the steel forming a protective layer on both sides of the sheet.

Gnee steel is able to supply all kinds of structural steel plate produced by En10025-2 standard, which mainly includes 4 major grades: S235, S275, S355 and S450, there's also more specific steel grades for different mechanical properties.

ASTM A572 Specification refers to High-Strength Low-Alloy Steel Plate for structural building, among the 5 steel grades of 42, 50, 55, 60 and 65, Grade 50 is one most common steel in applications where need more strength and less weight, use steel plate of this grade other than ordinary carbon steel will make the steel structure with same steel strength but lighter weight.
