Definition
DX: The first letter D stands for flat steel for cold forming, and the second letter X stands for the rolled state of the unspecified base material.
51~57: The numbers indicate the steel grade number; the D after the two digits is the code for hot-dip galvanizing. Z means the coating is pure zinc, ZF means galvanized iron alloy, AZ means galvanized.
DX52D is a European standard, the first “D” indicates that this is a cold forming steel, and the second “D” indicates that the process technology is hot-dip galvanized alloy.
DX52D (brushed quality) is available in the following hot dip coatings: DX52D+Z (galvanized), DX52D+ZF (galvanized-iron), DX52D+ZA (galvanized-aluminum), DX52D+ AZ (aluminum-zinc), etc. Z is available in coating qualities of 100, 140, 200, (225), 275 g/m², ZF is 100, 120 and (140)** g/m², ZA is 95, 130, 185, 200, 255 and 300* g/m², AZ is 100, 150 and 185 g/m², AS is 60, 80, 100, (120) and (150) g/m².
DX52D advantages
The advantages are: – higher corrosion resistance – excellent formability – low crack susceptibility of the coating The material is used for construction parts with good cold formability and high corrosion resistance.
Coated steel can be welded by the usual methods. Furthermore, in each case, after a suitable surface treatment in advance, the adhesive suitability and the coatability of organic materials are given.

In Conclusion
DX52D galvanized sheet is also a relatively common galvanized sheet. DX52D is a galvanized sheet with a variety of materials inside, which can be made into zero sequins or ordinary flower sequins. But only for simple bending and deformation.
