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 term is an extension of GI which is a traditional abbreviation for Galvanized Iron. Today the term GI typically refers to essentially pure zinc (>99%) continuously hot dip coated steel, as opposed to batch dip processes. 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.

PPGI coils are placed on machines as input for the profiling. Before providing to profiling machine a layer of lamination from lamination coil placed over the top of PPGI coil and passed through the laminating pressing part of the profiling machine. The laminating press machine presses this lamination cover to the PPGI sheet which saves the coating of PPGI sheet during profiling, cutting and transportation from scratches. Also the branding of the company is already printed on lamination which is placed over Raw PPGI coil.

Profiling of laminated PPGI coil is done while PPGI coil passes through different sections of profiler. During profiling PPGI coil undergoes various process (such as ribbing or bending) depending upon the design of profiler. In our factory we design multiple types of profile sheets in which famous ones are Tile Profiling, Bamboo Profiling, Hi Rib Profiling, Normal Corrugation Profiling, Ridge Profiling, Valley Morakh Profiling and Penalling of these PPGI coils. These designs not only provide the strength & durability to the PPGI Sheet but gives them a better look. We have high quality profilers that do best ribbing during the design with 99% accuracy.

Collecting the ready profiled sheet after being cutted out of PPGI coil and storing one over another to store the sheets for loading.
