GP Coils are a kind of steel coil wherein a thin protective coating of zinc is applied to enhance its resistance to corrosion. This is typically achieved through a hot dip operation, which enhances adhesion and abrasion resistance.
Hot Dip Galvanising (HDG) is a cost-effective control process that solves the majority of corrosion problems. HDG's widespread use is due to its ability to protect the substrate in two ways: firstly, as a barrier by providing a strongly-bonded zinc coating covering the steel surface, thus shielding it from environmental attack. Secondly, zinc offers cathodic protection which means that it sacrifices itself to protect the substrate if it gets damaged. Its low cost, ease of application, and long maintenance-free service make it the preferred method for protecting steel.
However, it is critical to note that GP Coils have limitations in certain environments. For instance, strong acids and alkalis, as well as sulphur-rich settings, can quickly corrode both the zinc and the steel. Therefore, before selecting any GP Coil, one must have an in-depth understanding of the end application and its environment
Features

High Corrosion Resistance - The use of high-grade pure zinc and uniform coating helps to provide superior resistance against Red and White Rust.
Superior Zinc Coating Adhesion - Electrolytic cleaning of the steel substrate before coating ensures excellent adhesion of the zinc coating.
Excellent Surface Finish and Flatness - The process of Wet Skin Passing enables improved surface texture and shape retention, resulting in an absolutely flat surface.
Optimum Malleability & Ductility - The application of strict controls on process parameters from the Raw Material stage to steel production ensures the desired quality for Commercial to IF grades of steel, providing optimum malleability and ductility.
Superior Paint Adhesion - GP Coils with a true zero spangled surface and an RA factor ranging between 0.8 - 1.4 ensure superior paint adhesion and better finish, without any spangles or crushed spangles, thus lowering the cost of paint required.
Consistent Thickness - The state-of-the-art Tandem Cold Rolling Mill has installed an Automatic Gauge Control (AGC) mechanism which guarantees consistent and precise thickness across the material. This results in a higher yield of end products, as more parts can be obtained per kilogram of GP Coils.
Applications
Automobile - GP Coils are used to produce air and oil filters, fuel and oil tanks, exhaust pipes etc.
Appliances - GP Coils are used to make various components of Air Conditioners, Refrigerators, Washing Machines, Microwave Ovens, Air Coolers, Gas Stoves, Coolers etc.
Ducting - GP Coils are widely used in the HVAC industry. They are used to create different components such as air ducts, venting systems, and exhaust pipes
Furniture - GP Coils are often used as structural supports for pieces such as shelves, cabinets, and tables. They can also be used as veneers, providing a sleek and modern look to any piece of furniture. They are highly maleable which allows for creative freedom in furniture manufacturing.
Agriculture - GP Coils are frequently used in the construction of sheds, barns, greenhouses, and other structures requiring a protective covering. They are also used as roofing, fencing, and wall cladding materials, providing long-lasting protection.
Others - GP Coils have a range of other applications, including their use in creating boxes, sandwich panels, solar heating panels and for general engineering and fabrication purposes.
