Hot Dip Galvanizing

(0 reviews)
  • Supplier : Fabrication And Galvanizing Technologies Company Ltd (GALVATEC)
  • Service Description : Hot Dip Galvanizing (HDG) is the best way to protect steel from corrosion since its lowest initial cost, durability, longevity, availability, versatility, sustainability, and even good appearance and finish. HDG is the process of immersing fabricated steel or iron into a kettle (bath) of molten zinc. When in the kettle, iron in the steel metallurgical reacts with the zinc to form a tightly bonded alloy coating. During the reaction in the kettle, the zinc interacts with the iron in the steel to form a series of zinc-iron alloy layers. A cross section of the galvanized steel coating shows a typical microstructure comprising of three alloy layers in addition to a layer of pure metallic zinc. So even when the first layer (ETA) is scratched, the steel is still protected by another three hard layers.The thin Gamma layer composed of an alloy that is 75% zinc and 25% iron. The Delta layer composed of an alloy that is 90% zinc and 10% iron. The Zeta layer composed of an alloy that is 94% zinc and 6% iron. The outer ETA layer that is composed of pure zinc. We take pride in our ability to furnish a quality zinc coating to meet your specifications. Galvatec has the experience and the unique capability to exercise full control of quality, cost & time which reflects on the customer satisfaction.

Additional Information

Features

  • GALVATEC is technically specialized for galvanizing miscellaneous metal fabrications such as Structural Steel, Telecommunication Transmission tower members, lighting poles, pipes, welded brackets, beams, frames, rods, gratings, cable trays, cable ladders and all types of cable support systems, as well as many other items for a wide variety of customers and industries. The galvanizing process consists of three basic elements: surface preparation, galvanizing, and inspection. Prepurchasing Steel - In order to guarantee the finish, quality & cost saving of the hot dip galvanizing process, full cooperation between fabricator and galvanizer should be established. The steel fabricator purchaser should do all the efforts to Purchase the steel with the chemical composition Carbon less than 0.25%, Phosphorus less than 0.04%, Manganese less than 1.35% and Silicon levels less than 0.04% or between 0.15% - 0.22%. Welding or bending-induced stress that reside in the material after fabrication may be released during galvanizing, also resulting in structural changes in shape and/ or alignment (distortion and warping). Bracing - Permanent or removable after galvanizing provides stability during the thermal expansion and contraction cycle. Occasionally, when Bracing is not used and Warping and/ or distortion occur, the part will return to its original shape during cool-down.
