Galvanized Coil

Prepainted galvanized steel coil is a kind of colour coated steel coil (PPGI coil). It uses galvanized steel as the base metal. The zinc layer offers strong corrosion resistance. Plus with painting, it is more durable than galvanized steel.The metallic coated steel then experiences some cleaning procedures, pre-treatment solutions and ultimately gets multiple layers of organic coatings, including laminates, vinyl dispersions, and paint. This continuous technique of applying different coatings is referred to as coil coating. Therefore, the steel coil doesn’t require painting or finishing when employed in finished products.

Galvanized Coil 

Galvanizing is the process of applying a protective zinc coating to steel.

Carbon steel that has gone through this chemical process of galvanizing to keep it from corroding is called Galvanized Steel.

The zinc layers created during the galvanizing process produce a protective coat around the steel, locking out moisture and averting corrosion.

Galvanizing also enhances adhesion and abrasion resistance.

Advantages

Some of the advantages of Galvanized Coils & Sheets include -

• Corrosion Resistance - High-grade pure zinc coupled with uniform coating ensures highest Red Rust resistance.
• Uniform & Superior Zinc Adhesion - Superior Zinc adhesion is achieved through electrolytic cleaning of steel substrate before coating.
• Absolute Flatness - Absolute flatness is possible through 'Wet Skin Passing', which ensures improved surface texture and superior shape retention.
• Optimum Malleability & Ductility - Best substrate steel quality is achieved by applying close controls on process parameters right from Raw Material [Iron ore & Coal] stage to steel production ensuring desired quality right from Commercial to IF grades of steel.
• Superior Paint Adhesion - True zero spangled surface with RA factor varying between 0.8 - 1.4 ensures superior paint adhesion, better finish due to absence of spangles/crushed spangles, which also lowers paint requirement and hence, lowers the cost.

Applications

Some of the applications of Galvanized Coils & Sheets include -

 

• Automobile industry - Galvanized Coils & Sheets are used to produce air and oil filters, fuel and oil tanks, exhaust pipes etc.
• Appliances industry - Galvanized Coils & Sheets are used to make various components of Air Conditioners, Refrigerators, Washing Machines, Microwave Ovens, Air Coolers, Gas Stoves etc.
