Pre-painted galvanised steel coil introduction
PPGI is based on galvanized steel coils and further undergoes pre-coating treatment. This type of steel coil not only has excellent corrosion resistance but also features various color coatings, making it suitable for a wide range of construction and decoration fields. The production process of pre-coated galvanized steel coils includes cleaning, painting, and curing of the galvanized steel coils, ultimately forming a firm coating that protects the steel coils from corrosion and endows them with different colors.

FAQ
1. What is pre-painted galvanized steel?
A pre-painted steel product generally consists of three layers: a steel sublayer with a zinc-based coating, an undercoat called primer and a layer of surface paint called finishing coat. The sublayer directly affects the installation of the product and its resistance to corrosion.
2. What are the advantages of pre painted steel?
3. How long does painted steel last?
Sun, heat, wind and weathering are constants that result in paint typically requiring touch-up and replacement in 12-15 years, costing far more than galvanizing over the intended life of the project.
