DC56D+ZF is an ultra-deep drawing galvanized iron alloy coil.
Cold rolled coil (annealed state): It is obtained by bell annealing before rolling. After annealing, its work hardening phenomenon and internal stress are eliminated (greatly reduced), that is, the yield strength is reduced close to that of cold rolling. forward. Cold-rolled coils are made of hot-rolled coils as raw materials and rolled at room temperature and below the recrystallization temperature, including plates and coils. Among them, those delivered in sheets are called steel plates, also called box plates or flat plates; those that are very long and delivered in rolls are called steel strips, also called coiled plates.
Zinc-iron alloy sheet is also called alloyed galvanized sheet. The alloying process heats the galvanized strip steel through the alloying furnace to 550~560°C in 5 to 10 seconds, so that all the pure zinc layer is converted into iron-zinc alloy. Its weldability, coating performance, heat resistance, and corrosion resistance are all better than ordinary galvanized sheets.

Galvanized Steel Sheet Show：
The galvanizing process has become an important anti-corrosion method for steel, not only because zinc can form a dense protective layer on the surface of steel, but also because zinc has cathodic protection functions. When the zinc coating of galvanized steel sheets is damaged, iron-based corrosion can still be prevented through cathodic corrosion protection. Galvanized steel sheet coil is a type of hot-dip galvanized steel sheet. Galvanized sheet refers to a steel sheet coated with a layer of zinc on the surface.
Galvanized Steel Plate：
The advantages of galvanized coils and plates are long anti-corrosion life and wide adaptability to the environment. It has always been a popular anti-corrosion treatment method and is widely used in light industries such as ship components, building steel structure components, and substation auxiliary facilities.
