Galvanized steel sheet Introduction:
The surface of welded steel plate has hot dip galvanized layer or electricwelding steel plate which called the galvanized steel sheet. The greatest advantage of galvanized steel sheet is excellent corrosion resistance, painting, decoration and good formability. In recent years, the using of galvanized steel plate in the car has been rising, and become the subject of automotive sheet. Countries around the world are studying how to enlarge the varieties, specifications of galvanized steel, improve the coating process and then improve the quality of the coating, including corrosion resistance, anti chalking peeling, coating, welding.
Purpose: Galvanized steel galvanized products are widely used in construction,household appliances, vehicles and ships, container manufacturing industry, electromechanical industry, almost involves all areas of basic necessities of life. In recent years, the demand of galvanized steel increases unceasingly and the production is also growing quickly. in the United States, Japan and other steel producing countries, as a proportion of the galvanized steel in steel has been as high as 13% to 15%.
Galvanized steel sheet parameters:
Galvanized scale value: galvanized is a widely adopted way in implying galvanized plate the zinc coating thickness, including two sides to galvanized quantity is the same (i.e. galvanized thick Galvanized)and two differences (that is, thick Galvanized) .
Units on a continuous cold-rolled strip steel or steel sheet,galvanized steel (electro galvanized,Pre-painted steel coil hot galvanized,Galvalume and cold-rolled plate) as the substrate, after surface preparation (degreasing and chemical treatment), pre-painted galvanized steel coil/hot dipped galvanized steel coil by a roll coating method, applying one or more layers liquid coating, after baking and cooling the resulting sheet is coated steel.Pre-painted steel coil Since the coating can have a variety of colors, it is customary to coated steel is called color coated steel sheet (PPGI).

pre-painted galvanized steel coil/hot dipped galvanized steel coil is the material which uses galvanized steel as the basic substrate metal. PPGI is prepainted galvanized steel, also known as precoated steel, coil coated steel,Pre-painted steel coil color coated steel etc.pre-painted galvanized steel coil/hot dipped galvanized steel coil A galvanized steel sheet in coil form is cleaned, pretreated, applied with various layers of organic coatings which can be paints, vinyl dispersions, Pre-painted steel coil or laminates.pre-painted galvanized steel coil/hot dipped galvanized steel coil are applied in a continuous process known as Coil Coating.The steel thus produced in this process is a prepainted, prefinished ready to use material.
