    Description

    Galvanized shingles are steel sheets with a zinc coating on the surface.


    Galvanized roof tiles are steel sheets coated with a layer of zinc. Galvanizing is an economical and effective method of corrosion protection, and approximately half of the world's zinc production is used for this process.


    Galvanized roof tiles are manufactured by coating the surface of a steel sheet with a metallic zinc layer, which prevents surface corrosion and prolongs its service life; this zinc-coated steel sheet is called galvanized steel sheet.



    1. Galvanized Steel

    - Description: Galvanized steel is coated with a layer of zinc to protect against corrosion.

    - Characteristics:

    - Corrosion Resistance: Good, but the zinc layer can wear off over time.

    - Durability: Moderate, with a lifespan typically ranging from 20 to 50 years.

    - Cost: Generally lower than other coated steels.

    - Applications: Suitable for a variety of roofing applications, including residential, commercial, and agricultural buildings.

    - Pros:

    - Affordable.

    - Widely available.

    - Cons:

    - Corrosion protection diminishes if the zinc layer is damaged.

    - May require maintenance over time.


    Product advantages


    Galvanized shingles are widely used in various environments and have a long service life of corrosion protection, which depends on the environment.


    Low processing costs, galvanized shingles have lower corrosion costs than other coatings.


    Durability, in suburban environments, standard galvanized anti-corrosion coatings remain intact for more than 50 years without repair. In urban and marine areas, standard galvanized anti-corrosion coatings last up to 20 years without repair.


    Reliability. The durability of the coating is relatively reliable because the galvanized coating is metallurgically bonded to the steel and becomes part of the hard surface.


    The coating is tough and the galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
