Galvanised Steel Coil The unique nature of the galvanizing process – formation of a series of zinc iron alloy layers – provides a tough and abrasion resistant coating. You can tell when metal is galvanized because the zinc makes a distinctive pattern on the metal called “spangle.”

Traditionally continuously hot dip zinc coated steels are used for such applications. However, off late the quest for further extending the longevity of the coil coatings has led to the replacement of the zinc coating with a host of other hot dip zinc–aluminium alloy coatings such as Galvalume ®, Galfan ®, ZAM ®, SuperDyma ®, etc. Each of these metal coatings has its own unique metallurgical features
May 08, 2007 · A zinc coating, usually hot dipped, in which the zinc and steel form a metallurgical bond. The thickness of a hot dipped coating can be varied from a thin zinc/iron alloy layer to heavy applications suitable for extended outdoor exposure. Electrogalvanized. Also a zinc coating, but applied in a cold, electrolytic bath rather than a molten zinc
Galvalume® steel is coated with an aluminum zinc alloy that combines the corrosion protection of aluminum with the galvanic protection of zinc.
The most commonly used coating material is zinc which can be applied either using the heat process (hot dip galvanising) or using electrolysis (electro galvanising). An organic coating (paint, plastic) can also be deposited on the zinc layer. Coil. A finished steel product such as sheet or strip which has been wound or coiled after rolling. Coke
Resin Coating. A resin coating is also available on our 55% Aluminum Zinc Alloy Coated Steel. This water based resin coating is formulated to resist finger printing and scuffing during product handling, improves resistance to wet stack stains occurring during transport and storage, and virtually eliminates the need for roll forming lubricants.
American Elements specializes in producing high purity uniform shaped Zinc Coil with the highest possible density for use in semiconductor, Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD
Aluminum Zinc alloy Coated Steel Sheet (ALCOAT) Aluminum Zinc Alloy Coated Steel Sheet Galvalume. The alloy coating comprises about 55% aluminum 43.4% zinc and 1.6% silicon. This coating combines the superior corrosion resistance of aluminum with the cut edge protection of zinc.
The improved corrosion resistance of 55% Al Zn Alloy Coated Steel Coils are derived from the unique combination of the barrier protection of Aluminum and the sacrificial protection of Zinc. The formation of an insoluble Aluminum oxide layer provides the barrier protection while Zinc provides a sacrificial protection at cut edges, scratches and areas of coating damage.
Resist rust, fire and elemental onslaughts with galvalume steel sheet and coil from Alliance Steel. Galvalume steel is carbon steel coated with an aluminum zinc alloy using a continuous hot dip process, combining the corrosion protection and high temperature resistance of aluminum with the formability and galvanic protection of zinc.
Coatings of metallic zinc are generally regarded as the most economical means of protecting against corrosion. Seven methods of applying a zinc coating to iron and steel are in general usehot dip galvanizing, continuous line galvanizing, electro galvanizing, zinc plating, mechanical plating, zinc spraying, and painting with zinc bearing paints.
