GI is the abbreviation for Galvanized steel. GI typically refers to essentially pure zinc (>99%) continuously hot dip coated steel, PPGI refers to factory pre-painted zinc coated steel, where the steel is painted before forming, as opposed to post painting which occurs after forming. The hot dip metallic coating process is also used to manufacture steel sheet and coil with coatings of aluminium, or alloy coatings of zinc/aluminium, zinc/iron and zinc/aluminium/magnesium which may also be factory pre-painted. While GI may sometimes be used as a collective term for various hot dip metallic coated steels, it more precisely refers only to zinc coated steel. Similarly, PPGI may sometimes be used as a general term for a range of metallic coated steels that have been pre-painted, but more often refers more precisely to pre-painted zinc coated steel. As the name implies, Coating Galvanized Steel Strip is a steel sheet coated with a layer of zinc on the surface. Zinc plating on the steel sheet is one of the economical and effective ways to avoid rusting of the steel sheet. Because of its high cost performance, galvanized steel sheet is widely used For the production of outdoor bulletin boards.
What are the advantages galvanized steel?
1. The Coating Galvanized Steel has been very popular in adapting to a wide range of environments and has a long anti-corrosion period, but the anti-corrosion period is different in different environments. 2. The treatment cost is low, and the cost of galvanized sheet anti-rust is lower than that of other paint coatings. 3. Durable and durable. In the suburban environment, the standard galvanized antirust layer can be maintained for more than 50 years without repair. In urban areas or offshore areas, the standard galvanized antirust layer can be maintained for 20 years without repair. 4. Good reliability, the metallurgical combination between the galvanized layer and the steel is a part of the rigid surface, so the durability of the coating is more reliable. 5. The toughness of the coating is strong. The galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation and use. 6. Integral protection, every part of the plated parts can be plated with zinc, even in the depressions, sharp corners and hidden places can be fully protected. 7. Save time and effort, the galvanizing process is faster than other coating construction methods, and can avoid the time required to paint on the site after installation. shandong esbs new material (www.ppgippgi.com) is a china factory,we are engaged in the galvanized steel coils,prepainted steel coils more than ten years ,we can meet all your requirments and customizations.welcome to visit us.
