galvanized steel coil
● Hot Dipped Galvanized Coil is widely used in auto, household electrical appliance, IT, advanced building materials industries, etc. The process of producing hot dipped galvanized coil is: Cold Rolled Full HardPayoff ReelsDegreasingAnnealingZinc CoatingTension LevelingStraightedge FormingChromate or Oil.

Ruijie Steel stocks Hot dipped Galvanized Coil and also Manufacture in:
  • Thickness: 0.23 mm-1.50 mm
  • Width: 700 mm-1250 mm
  • I.D.: 508 mm, 610 mm
  • Coil weight: 3-15 MT
  • Zinc Coating:70-275g/m²
  • Spangle:Minimum / Regular
  • Standard: JIS G3302, ASTM A653M, EN10327, etc.

● Hot-dip Galvalume Steel Coil (GL) is substrated on Cold Rolled Steel (CRC) in carious strength and specification. Coating composition is 55% aluminum in weight ratio, 43.4% zinc, and 1.5% silicon, with excellent corrosion and heat resistance performance. Hot-dip aluminum-zinc alloy-coated steel technology is successfully developed from Hot-dip alumiunm and Hot-dip Galvanized processing, provided with long-term corrosion resistance and heat anti-oxidation resistance of aluminum and galvanic behavior effect of zinc, exerted their characteristics most.
