Use:

Galvanized roofing sheet are mainly used to make inner and outer covering parts and structural parts that require formability and corrosion resistance in automobile, construction, household appliances and other industries.Galvanized sheet products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grilles, etc.; the light industry industry uses it to manufacture household appliance shells, civil bacon, kitchen utensils, etc., and the automotive industry is mainly used to manufacture corrosion-resistant parts for cars etc.; Agriculture, animal husbandry and fishery are mainly used for food storage and transportation, meat and aquatic products freezing processing tools, etc.;It is suitable for industrial and civil buildings, warehouses, special buildings, large spansThe roof, wall and interior and exterior wall decoration of steel structure houses are light in weight.High strength,, convenient and quick construction, earthquake resistance, fire prevention, rainproof,Long life, maintenance-free and other characteristics, has been widely used.

Classification:

Corrugated boards are usually classified in various ways according to the application site, board wave height, lap structure, and material.

Common classification methods are as follows:

(1) According to the classification of application parts, it is divided into roof panels, wall panels, floor decks and ceiling panels. In use, the color steel plate is used as the wall decoration board at the same time, and the architectural decoration effect is relatively novel and unique.

(2) According to the wave height classification, it is divided into high wave plate (wave height ≥70mm), medium wave plate and low wave plate (wave height <30mm)

(3) Classification by substrate material – divided into hot-dip galvanized substrate, hot-dip galvanized aluminum substrate, and hot-dip galvanized aluminum substrate.

(4) According to the structure of the board seam, it is divided into lap joint, undercut and withhold structure, etc. Among them, the undercut and crimped medium and high wave boards should be used as roof panels with high waterproof requirements: the lapped medium and high wave galvanized sheets are used as floor coverings; the lapped low wave boards are used as wall panels.
