DX51d SGCC Prepainted Cold Rolled Steel Coil For Roofing Sheet 600 - 1250MM
DX51D SGCC Coating Cold Rolled Galvanized Steel Coil For Roofing Sheet
Galvanized steel coils production process:
- Uncoiler
- Welder
- Entry Looper
- Pre-treatment
- Annealing Furnace
- Zinc Pot
- Cooling Tower
- Water Quench Tank
- Skin Pass
- Tension Leveler
- Passivation Coater
- Exit Looper
- Recoiler
The production and processing of galvanized steel coils can be divided into three steps: first, the entire coil is pickled to remove rust and dirt, so that the surface of the galvanized steel strip can achieve a bright and clean effect; after pickling, pass ammonium chloride or zinc chloride It is cleaned in an aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the hot-dip plating tank for the galvanizing process; after the galvanizing process is completed, it can be put into storage and packaged.
