Coated Flat Steel Product Types and Applications

Galvanized coil and Galvalume coils are manufactured from cold rolled coil, and the production process is as follows: The coils, after undergoing hot dipped galvanizing treatment, demonstrate excellent performance in corrosive environments. Galvanized steel coil possesses a variety of advantages, namely, relatively high mechanical strength, strong durability, inertness to aggressive chemicals and thermal impacts, corrosion-resistant properties enabling resistance to sudden fluctuations in humidity and temperature, suitability for all types of processing operations, a protective performance that can be maintained for an extended period, and relatively high plasticity of the material.


In light of its multi-functional features, GI coil galvanized steel/ GL Coil are widely utilized in numerous fields:


  • Construction Sector

With regard to the roofs and exterior walls of residential buildings, gi hot dip galvanized steel coils / galvalume steel coils can serve as waterproof and protective layers. In large-scale commercial complexes, they are employed in the construction of building skylight structures and can also be utilized in the construction of protective railings and ventilation ducts.

In industrial buildings, they are predominantly used for enclosure structures and the fabrication of factory shelves, among other applications.


  • Automotive Industry

This material is applied in the manufacturing of the front-end and internal parts of vehicle bodies and is also frequently used in the repair work of the front-part components of trams, buses, and trolleybuses.

  • Mechanical Engineering and Instrumentation

The housings of electromechanical equipment, household appliances, and metering devices are fabricated from pre-painted galvanized steel coil / galvalume steel coil az150, effectively ensuring that the instruments operate normally under diverse environmental conditions and preventing external factors from interfering with the internal circuits and sensors of the instruments.


  • Other Areas

Galvanized steel plate /aluzinc coils are also extensively used in the construction of marine containers, railway freight cars, and furniture manufacturing.

Color coated galvanized steel coil plates are produced by chemically treating the surfaces of steel plates (prepainted galvanized steel coil,

prepainted aluzinc steel coil), followed by coating and secondary baking. Pre-coated steel plates for construction, due to their long-lasting color, good durability, and resistance to chalking, have become highly appealing substitute materials for wood and other materials, which can minimize maintenance costs to a great extent. Simultaneously, the characteristics of multiple colors, surface structures, and coatings offer a high degree of flexibility and abundant choices for such products. Pre-coated steel plates for household appliances are typically based on electro-galvanized, hot-dip galvanized, and cold rolled steel plates and are widely used in the manufacturing of refrigerators, large-scale air conditioning systems, and refrigerators, etc.
