ZINC COATED GALVANIZED STEEL COIL FOR CORRUGATED METAL ROOFING IRON STEEL SHEET

Does galvanized metal rot?
Galvanization is a zinc coating applied over the top of steel. It prevents rust and corrosion far longer than paint will, often for 50 years or more, but eventually that brown rot will set in.
Why you shouldn't weld galvanized steel?
When galvanized steel is welded, the zinc coating at and around the weld burns away, leaving the area uncoated and unprotected. As a result, the unprotected bare weld could suffer from expedient weld failure.
How do you keep galvanized steel from rusting?
The most important step in preventing corrosion on galvanized steel is keeping it out of environments where it is exposed to substances with a pH below 6 or above 12. One side of this requirement is that it is important to keep galvanized steel out of acid rain.
For galvanized steel coils, the steel sheet is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ℃ to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.

Product Advantages
1. Cheap: The cost of aluminized zinc is lower than that of other coatings.
2. Reliable: The aluminized zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.
3. Strong toughness: The aluminized zinc layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
4. Comprehensive protection: Every part of the plated piece can be aluminized zinc, and is fully protected even in depressions, sharp corners and hidden places.
5. Save time and energy: Aluminized zinc process is faster than other coating methods.

Product Application
Aluminized zinc steel coil products and galvanized steel coils are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and other industries. Such as building roofs, highway guardrails, sheet metal processing, roof grilles, household appliance enclosures, ventilation ducts, chimneys, kitchen utensils, grain storage and transportation, frozen processing of meat and aquatic products, etc.
