Process of Prepainted Galvanized SteelCoil:
Pay off reel → double cut shear → welder-notcher → entry accumulator → pre cleaning section → furnace → hot bridle → zinc pot → air knife → after cooler → water quench → dryer → skin pass mill → dryer → tension leveler → dryer → chemical coater → chemical oven → cooler → exit accumulator → oiler → exit shear → tension reel.

Selected equipment is indispensable for superior quality. SMC's cold rolling mill equipment was imported from SMS Demag of Germany and from Italy. So rare were any domestic companies to own so worldly advanced processing facilities. The pickling, acid regeneration, and hot-dip galvanizing lines matching the cold mill are also purchased from well-known domestic companies. These advanced production equipments have surely laid a solid foundation for producing superior products.

Test Equipments of Prepainted Galvanized SteelCoil:
Salt-spray tester; Atomic absorption spectrophotometer; Rockwell typer hardness tester; Tensile test machine; Metrohm titration; Laboratory Bend test machine

Features of Prepainted Galvanized SteelCoil:

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.

Applications of Prepainted Galvanized SteelCoil:

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.

Structure of GI/PPGI

Our Prepainted Galvanized SteelCoil:

Our High Quality PPGI Packing Packing:

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), secondary ppgi steel coils 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).

secondary ppgi steel coils 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.secondary ppgi steel coils 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.secondary ppgi steel coils 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.
