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.
