Generally manufactured with hot dip zinc coated(GI) steel or an aluzinc/galvalume(AZ/GL) substrate, the coil is processed on a continuous paint coating line (CCL) where in the surface of the metal is cleaned, pre-treated and applied with various layers of organic coatings.
At DANA STEEL Our product range of color coated material combines the strength and form-ability of steel with the corrosion resistance of zinc and paint. We have the widest range of colors in the market. Further,shades and degree of gloss can also be tailored to suit your requirement.DANA STEEL‘s Color Coated Prepainted Galvanized Steel Coils & Prepainted Aluzinc Steel Coils (PPGI / PPGL ) could be supplied as coils, sheets, slit strips or even profiled sheets. Our Installed Annual Coil Coating Capacity is 150,000 Metric Tonnes in thicknesses range of 0.18mm – 2.0mm (for Prepainted Galvanized/Aluzinc Coils) wih 650mm-1350mm width range.
Continuous Coil coating is a continuous and highly automated process for coating galvanized / Aluzinc substrate before fabrication. In one continuous process both the top and bottom sides are cleaned, chemically treated, primed, oven cured, top coated, oven cured again, rewound/recoiled and packaged into final prepainted galvanized steel (ppgi) or prepainted aluzinc(ppaz/ppgl) steel coils.
Domestic Packaging for DANA STEEL Pre-painted CoilsAccurately done & Precise Coil coating provides beautiful topcoats, durable surfaces, innovative applications, green benefits, and cost savings.Coil coatings comprise liquid paint in a wide range of colors and finishes that can be applied to continuous galvanized(gi) or aluzinc(az) steel strip. These can be cured in seconds and recoiled & packed for delivery to end users. The coil coating process not only creates new markets for sheet metal products, but also reduces the environmental impact by minimizing paint waste and making use of excess solvents. At DANA STEEL in our ultra-modern Color Coating Line (CCL), evaporating paint solvents are re-incinerated to generate heat for curing ovens, thus preventing wastage of fuel and pollution .
Process Layout – DANA STEEL Color Coating Line (CCL#1)Primers
Epoxy – Polyester (Chrome – Chrome Free); for excellent corrosion and inter-coat adhesion. The Back Coat of the PPGI/PPAZ strip is Generally Polyurethane(PU)-Compatible Expoxy coated inorder to have adhesion in case the coils are used for insulated sandwich panel manufacturing.
Topcoats
R.M.P (Regular Modified Polyester)
Regular Modified Polyester is most widely-used coil coating with durable Polyester paint and heat dried. It is applied to interior/exterior materials with no heavy drawings. Thanks to its variable colours and glosses with an economic feasibility. RMP coated products are used for exterior panels and interior design purposes that do not require excessive processing. It generally displays superior workability, durability, and weather resistance and used for a variety of purposes; offered in a wide array of colours and degrees of polish.
Matt and wrinkle effect can be added to the top finish.
End Usage:
S.M.P (Silicon Modified Polyester)
Silicon Modified Polyester is a silicon resin modified Polyester paint coated and heat dried. Due to its higher durability than the Regular Polyester, generally applied for building construction. SMP assures economic benefits under circumstances of sea-side or industrial zones. 10-15 years limited warranty provided.
SMP products are coated and baked with paint containing silicon resin. It is suitable for coastal area due to its excellent weather resistance.
End Usage:
Public Construction Material, Sandwich Panel,
Corrugated Roof in Industrial Complexes, Airport, etc.
H.D.P (High Durable Polyester)
High Durable Polyester is high weather proof resin is developed with Hydrogenated monomer & Neo structure monomer. Assures similar durability as PVDF, but with more competitive price and advantages of various colours & gloss. 10-15 years of limited warranty provided.
Can be coated into a various pattern, inspired by customers’ needs.
End Usage:
Metal Exterior, Plant, Roof, Gutter, Roof, Industrial Building, etc.
P.V.D.F (Poly vinylidene Fluoride) / PVF2
Poly vinylidene Fluoride or PVF2 coil coating assures high weatherproofing against climate and durability, wear resistance & mach-inability. With PVDF unique painting technique, can be made into a simple mono colour type (Solid/Metal/Mica) as well as in various pattern types. PVDF(fluorine-carbon) coating made of fluorine carbon resin, pigment, ester solvent, after high temperature roasting and baking, the paint is solidified to dry film with super weather resistance. The hydrophillic surface treatment will prevent dusts adhesion on the surface and enable dust to be removed easily.
PVDF/PVF2 coatings are especially resistant to solvents, acids and heat, and has low density compared to similar fluoropolymers.
20 years of limited warranty provided depending on the regions.Standard Warranty Certificate can be obtained from DANA STEEL on request.
End Usage:
PLASTISOL
Vinyl plastisols are dispersion of special, fine particle size PVC resins in plasticizing liquids which are used for galvanized /aluzinc coil coating by DANA STEEL. These materials are liquid at room temperature , but as the compound is heated in the finish oven, fusion takes place and the liquid is converted into a tough, homogeneous mass.
The benefits of plastisol coil coating are numerous. Plastisol coil coating can add color , cushion, texture, safety, and quiet to the surface of your product or part, while simultaneously resisting abrasion, corrosion and electricity. Heat or light stabilizers, flame retardants, bonding agents and other additives are available to meet a variety of specifications including Automotive and Military applications.
Plastisol coatings can offer properties such as non-slip, cushioning, color coding, electrical insulation, abrasion resistance, impact resistance, weather and corrosion resistance.
