Galvanized steel coils are commonly used for a wide variety of applications due to their excellent corrosion resistance, strength and versatility. Some of the most common uses for galvanized steel coils include.

Construction. Galvanized steel coil is widely used in the construction industry for roofing, siding and framing due to its strength, durability and ability to withstand harsh weather conditions.

Automotive industry. Due to its corrosion resistance and strength, galvanized steel coil is commonly used in the automotive industry for the manufacture of various components such as body panels, chassis components and exhaust systems.

Household appliances. Galvanized steel coils are used in the manufacture of household appliances, such as refrigerators, ovens and washing machines, because of their corrosion resistance and aesthetic appeal.

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 although lead in such amounts and alloyed with zinc is harmless. 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.

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.
