Metal Painting & Coating

Metal painting and coating is a specialised service that requires a deep understanding of metallurgy, surface chemistry, and corrosion science, and Islamia Paints & Decor brings this expertise to every metal painting project in Kolkata. Metal surfaces — whether mild steel gates and grills, wrought-iron balconies, aluminium window frames, galvanized iron roofing, or industrial MS structures and pipelines — are constantly under attack from Kolkata's high humidity, saline air (especially near the Hooghly river), and monsoon rainfall. Without proper protective coating, metal surfaces develop rust within months, leading to structural weakening, unsightly appearance, and eventual failure. Our metal painting service follows a rigorous, multi-step process: first, surface preparation by mechanical cleaning (wire brushing, sanding, or abrasive blasting for industrial applications) to remove all existing rust, scale, and old paint down to bare metal; second, application of a corrosion-inhibiting primer — typically zinc-chromate or epoxy primer from Asian Paints, Berger, or Sika — that creates a chemical barrier between the metal surface and the environment; third, intermediate coats of epoxy or polyurethane build coat that adds thickness and additional barrier protection; and finally, a topcoat of alkyd enamel, PU paint, or specialised industrial coating that provides UV resistance, colour retention, and a durable finish. For residential applications like main gates, balcony grills, and stair railings, we typically use a 3-coat system (primer + 2 topcoats) in a wide range of enamel colours including classic black, charcoal grey, metallic silver, and custom-matched shades. For industrial applications like structural steel, pipelines, and storage tanks, we design multi-coat systems using epoxy, polyurethane, and specialised coatings that meet specific performance requirements for chemical resistance, temperature tolerance, and service life. We also offer hot-dip galvanising consultation, powder coating referral, and regular maintenance painting programmes for large metal installations. Our services are available for residential, commercial, and industrial clients across all Kolkata areas.
