              PPGI Color Coated Steel Sheet in Coil

1.Description & Specification:

PPGI Coils PPGI Steel Coil PPGI Prepainted Galvanized Steel Coil
PPGI is pre-painted galvanised iron, also known as pre-coated steel, coil coated steel, color coated steel etc., typically with a hot dip zinc coated steel substrate

 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.

 Zinc coated steel substrate for PPGI is typically produced on a continuous galvanising line (CGL). The CGL may include a painting section after the hot dip galvanising section, or more commonly the metallic coated substrate in coil form is processed on a separate continuous paint line (CPL). Metallic coated steel is cleaned, pre-treated, applied with various layers of organic coatings which can be paints, vinyl dispersions, or laminates. The continuous process used to apply these coatings is often referred to as Coil Coating.

 The steel thus produced in this process is a prepainted, prefinished and ready for further processing into finished products or components. to use material.

 The coil coating process may be used for other substrates such as aluminium, or aluminium, stainless steel or alloy coated steel other than "pure" zinc coated steel. However, only "pure" zinc coated steel is typically referred to as PPGI. For example PPGL may be used for pre-painted 55%Al/Zn alloy-coated steel (pre-painted GALVALUME(r) steel*)

5.Application:

1. Buildings and constructions: roofing, ceilings, gutters,  venting lines, indoor decorations, window frames, etc.
2. Electrical appliances: computer shells, washing machines, refrigerators, dehumidifiers, video recorders, water heaters, etc.
3. Agricultural equipments: troughs, feeding tools, agricultural driers, irrigation channels, etc.
4. Vehicle parts:  back-seat plates of buses and trucks, conveying systems, oil tanks, etc

6.Advantage: 

1. Excellent corrosion resistance: The zinc layer provides a good protection of Pre-painted Galvanizeed Steel Sheet.
2. High heat resistance: The reflective surface of the material aids in efficiently reflecting the sunlight away and in turn reducing the amount of heat transmitted. The thermal reflectivity converts into energy savings.
3. Aesthetics: Pre-Painted Galvanized steel sheet is available in plethora of patterns and multiple sizes as per the requirements that given by our customers.
4. Versatility: can be used in the various areas.
