Galvanized Iron (G.I)

Hot dipped galvanized steel is produced by passicaptureng cold rolled steel through a molten bath of Zinc at temperatures around 460 °C. The Zinc acts as a physical barrier between the atmosphere and the surface of the metal. Further, due to its lower chemical potential than iron, it is attacked and dissolved first, thereby offering superior corrosion resistance ( cathodic protection ).

DANA Steel UAE with it’s headquarters in Dubai, and it’s coil service centers in Dubai & Ajman is one of the most prominent stockiest and service center for galvanized coils(GI coils) in the middle east.Our service centers are equipped to handle coil weights upto 20 MT and can cut/slit sheets upto tolerances of +/- 0.50mm .In Addition to Cutting & Slitting facilities we also provide custom fabrication jobs ( cutting/bending/perforation) for our valuable customers.

Galvanized steel can be identified by the crystallization pattern on the surface ( often referred to as “spangle” ). Regular, Minimal and Zero Spangle are the three types of surface finishes that are available.

The service life of this material would depend on the coating thickness, which is available between 90 to 500 grams per square meter.

GI has a wide variety of applications which include Roofing, Sidewall Partitions, False Ceilings, Decking, Steel Buildings, Automobile Components, Water Heater and Coolers, Furniture, Rolling Shutters, Sign Boards, HVAC Ducting and many more.

  • Superior corrosion resistance
  • Higher aesthetic value
  • Excellent workability and adherence to paint
