GI steel galvanized sheet metal roofing coated steel galvanized sheet metal roll galvanised coils pre painted galvanized steel

DX51D Hot Dipped Galvanized Steel coil/sheet

Product Introduction

Hot dipped galvanized steel coil/sheet, put based steel sheet in melting zinc, then it will be the sheet sticking of a layer of zinc.At present mainly adopts continuous galvanizing process, namely put the continuous roll of steel coil in the melt zinc plating tank,then alloying the galvanized steel.This kind of steel plate is made by hot dipped method, but after the leaving the zn tank, immediately heated to a temperature of about 500 ℃, it form a zinc and iron alloy membrane.This kind of galvanized coils has good coating of the adherence and weldability.

Primary Application

As to excellent cold bending molded ablity, excellent decoration effect, strong anti-corrosion ability, galvanized steel coils and are also pollution-free and easily recycled. Accordingly, they can be used as final products and basic plates of color coated steel coils and widely applied in construction, home appliances, decoration, ect.

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), GI steel galvanized sheet metal roofing coated steel galvanized sheet metal roll galvanised coils pre painted galvanized steel 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).

GI steel galvanized sheet metal roofing coated steel galvanized sheet metal roll galvanised coils pre painted galvanized steel 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.GI steel galvanized sheet metal roofing coated steel galvanized sheet metal roll galvanised coils pre painted galvanized steel 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.GI steel galvanized sheet metal roofing coated steel galvanized sheet metal roll galvanised coils pre painted galvanized steel 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.
