Product Description

Product Description


Corrosion resistance is a prominent advantage of galvanized channel steel. Considering that it will be used in various steel structure facilities, it will inevitably be in contact with the external environment for a long time, or it will be in contact with substances that may cause corrosiveness. The high corrosion resistance ensures that the galvanized channel steel is protected from the external environment and maintains its own structural stability.
Good reliability: the galvanized layer and the steel are metallurgically bonded and become part of the steel surface, so the durability of the coating is more reliable; the toughness of the coating is strong: the galvanized layer forms a special metallurgical structure, which can Withstands mechanical damage during transportation and use; comprehensive protection: every part of the plating can be galvanized, even in depressions, sharp corners and hidden places can be fully protected.

Hot Dipped Gi Steel Channel,Galvanization is the leading method to protect metals from environmental elements that cause corrosion, rust, and the eventual weakening of the steel. Hot-dip galvanizing deposits a thick, robust layer of zinc iron alloys on the surface of a steel item. When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide which further reacts with carbon dioxide to form zinc carbonate. A dull, grey, fairly strong material that stops further corrosion in most circumstances, protecting the steel from the elements. Galvanized steel is widely used in applications where rust resistance is needed. Galvanized steel can be welded however, you should exercise caution around the resulting fumes. Galvanized steel is commonly used in the automotive industry to enhance the corrosion performance of exterior body parts. Galvanized Steel is magnetic.

Process


The process of hot-dip galvanizing results in a metallurgical bond between zinc and steel, with a series of distinct iron-zinc alloys. The resulting coated steel can be used in much the same way as uncoated.

A typical hot-dip galvanizing line operates as follows:[2]

  • Steel is cleaned using a caustic solution. This removes oil/grease, dirt, and paint.
  • The caustic cleaning solution is rinsed off.
  • The steel is pickled in an acidic solution to remove mill scale.
  • The pickling solution is rinsed off.
  • flux, often zinc ammonium chloride is applied to the steel to inhibit oxidation of the cleaned surface upon exposure to air. The flux is allowed to dry on the steel and aids in the process of the liquid zinc wetting and adhering to the steel.
  • The steel is dipped into the molten zinc bath and held there until the temperature of the steel equilibrates with that of the bath.
  • The steel is cooled in a quench tank to reduce its temperature and inhibit undesirable reactions of the newly formed coating with the atmosphere.

Lead is often added to the molten zinc bath to improve the fluidity of the bath (thus limiting excess zinc on the dipped product by improved drainage properties), help prevent floating dross, make dross recycling easier and protect the kettle from uneven heat distribution from the burners. Environmental regulations in the United States disapprove of lead in the kettle bath. Lead is either added to primary Z1 grade zinc or already contained in used secondary zinc. A third, declining method is to use low Z5 grade zinc.[3]

Steel strip can be hot-dip galvanized in a continuous line. Hot-dip galvanized steel strip (also sometimes loosely referred to as galvanized iron) is extensively used for applications requiring the strength of steel combined with the resistance to corrosion of zinc, such as roofing and walling, safety barriers, handrails, consumer appliances and automotive body parts. One common use is in metal pails. Galvanised steel is also used in most heating and cooling duct systems in buildings

Individual metal articles, such as steel girders or wrought iron gates, can be hot-dip galvanized by a process called batch galvanizing. Other modern techniques have largely replaced hot-dip for these sorts of roles. This includes electrogalvanizing, which deposits the layer of zinc from an aqueous electrolyte by electroplating, forming a thinner and much stronger bond.
