Production Introduction
Galvanized Steel Coil Suppliers
Galvanized sheet: A thin steel sheet is immersed in a molten zinc bath to make the surface adhere to a layer of zinc. This galvanized sheet has good paint adhesion and weldability.
Production Process
Feeding → Uncoiling → Welding → Cleaning → Entry Looper → Annealing → Galvanizing / Galvanizing → Air Knife Scraping → Cooling → Finishing → Tensile Bending Straightening → Passivation, Fingerprint Resistance → Exit Looper → Surface Defect inspection→oiling→coiling and sampling→coiling→coil weighing and baling.
Different for full hard and soft material
Galvanized Steel Coil Suppliers
The full hard steel sheet refers to the steel sheet that is not annealed after processing, while the soft steel sheet is annealed.
Definition of hard steel sheet:
Using hot-rolled steel coil as raw material, cold rolling is carried out after pickling to remove oxide scale, and the finished product is a hard-rolled coil (hard steel sheet). The toughness-plastic index decreases, so the stamping performance will deteriorate, and it can only be used for parts with simple deformation. Because it has not been annealed, its hardness is very high (HRB is greater than 85), and its machinability is extremely poor. Only simple directional bending of fewer than 90 degrees (perpendicular to the coiling direction) can be performed.
Definition of soft steel sheet:
To put it simply, a piece of steel billet is heated (that is, the red hot steel block on TV) after being refined and rolled several times, then trimmed and straightened into a steel plate, which is called a soft steel sheet. . Soft steel plate is easy to process and has good ductility. Its hardness is generally around HRB65.

FAQ
Q1:Where is your loading port?
A: Qingdao or Tianjin Port
Q2:How soon can we get an email response from your team?
A: within 5 minutes
Q3:If we have some other product requirements that your page doesn't include, can you help supply them?
A: Yes
Q4: Does your product have warranty service? How long is the warranty period?
A: For regular paint thickness PPGI/PPGL can keep 3 years without fading, 5 years without paint peeling, 8 years of service life. (the higher paint coating and zinc coating, the longer service life.
For regular zinc coating, galvanized steel coil and galvalume steel coil can keep more than 5 years service life. The higher the zinc coating, the longer the service life.
The above is the result of using in a typical environment.
