Different Types of PPGI Coil | Metal n Machine the Best Supplier in UAE
PPGI Coil Supplier in UAE: A hot-dipped galvanised steel sheet or an aluminium sheet is used to cure the pre-painted steel sheet after it has been subjected to coating, reheating, and curing. Pre-painted galvanised steel coil, also called PPGI sheet, or colour scheme steel coil, are other names for hot-dip zinc-coated thin-film sheets of steel.
The foundation steel, coating, priming, and top paint/protective coating thickness of the pre-painted galvanised steel coil make up the total composition. The thickness of the rear layer is 5–20 mm, and the top layer is 10–25 cm thick. The cost of PPGI steel coil rises with the width of the base steel since manufacturing costs are rising.
Polyester (PE) is frequently used as a coating material for white or grey paint. The colour can be changed to match the RAL colour card or client samples. Creating distinctive patterns like wood grain, floral print, camouflage, and stone is useful.
Method Used to Make PPGI Coils
The steps involved in making these coils are baking, cooling down, finer coating, etched film, exporting loop, inspection plant, cutting, tangling, machine stitching, entering, processing, preliminary coating, baking, etc.
The adhesion of the primer to the galvanised layer of a colourcoated sheet can indeed be nice if the cleansing and antifouling procedures are poorly managed. The topcoat of the colour scheme steel coil decomposes readily during the pressing and forming procedure.
Types of Coatings
PPGI/PPGL coils can currently be coated with PE, PVDF, SMP, acrylic, PVC, and other materials.
PE
The PE-coated stainless steel sheet is simple to produce, easy to form, and reasonably priced due to its strong adherence. The
other level of UV and cracking resistance, however, is quite weak. Steel with a PE colour coating could be installed on the roof of regular civil structures.
SMP
Compared to PE, the SMP steel structure is more reliable. Silicone is not as robust as PE in terms of material adhesion and formability.
High-density polyethylene, or HDP
When compared to standard SMP coatings, the exterior weather durability is 16 years greater. It is far more adaptable and weather-tolerant.
PVC
PVC Due to environmental contamination, the PVC coating is rarely used.
PVDF
PVDF coatings have great colour retention and resistance to corrosion. It is the best grade of PPGI sheet coating for use in building construction.
Acrylic
Although the performance is excellent, the product is expensive and is used solely in certain industries (such as containers).
To choose a pre-painted galvanised steel coil that will fulfil your needs for the right type of steel, metal coating, qualities, and coating, you must consider your project's surrounding ecosystems, use, nature, and structural characteristics.
