Powder Coating Services – Durable Colour Finish for Long-Lasting Steel Protection

Powder coating is a high-performance, corrosion-resistant finishing process that gives your steel products a smooth, vibrant, and long-lasting surface. At United Steel Industries, we provide industrial-grade powder coating services for a wide range of steel materials — including angles, pipes, plates, sheets, and channels — to meet aesthetic and functional needs alike. Whether you're coating for durability, branding, or compliance, we deliver custom-colour powder finishes across South India.

What is Powder Coating?

Powder coating is a dry finishing process that involves electrostatically applying finely ground pigment and resin particles onto a clean metal surface. The coated object is then cured under high heat, forming a tough, unified film that’s far more durable than traditional liquid paint.

This method is widely used for steel structures, frames, architectural fixtures, signage, gates, panels, and industrial enclosures where both visual appeal and protection from wear, chemicals, and UV exposure are important.

Benefits of Powder Coating for Steel

• Corrosion resistance: Adds a protective barrier against rust, oxidation, and harsh environments
• Impact & scratch resistance :Stronger than liquid paint, ideal for high-traffic areas or machinery
• Uniform finish:No drips, runs, or sagging.
• Eco-friendly:Solvent-free, low-waste application
• Custom colours:Full RAL colour chart supported, including matte, gloss, textured, and metallic options
From RAL 9005 Jet Black to RAL 7035 Light Grey, our powder coating line is optimized for both mass production and one-off custom colour jobs.

Products Commonly Powder Coated

• 1. Mild Steel Angles & Channels:
  Used in structures and interiors. Powder coating gives a sleek, finished look with added weather protection.
• 2. Steel Pipes & Tubes :
  Perfect for railings, fencing, and industrial frames. Coated pipes resist UV rays and rusting, even in coastal areas.
• 3. Flat Bars & Plates:
  Powder-coated MS flats are widely used in gates, frames, doors, and machine platforms — enhancing both strength and style.
• 4. Perforated Sheets, Chequered Plates & Panels:
  Ideal for architectural metalwork and fabrication projects where appearance and durability are critical.
• 5. Steel Cabinets, Enclosures, Electrical Panels:
  Powder coating ensures insulation, scratch resistance, and longevity for electrical infrastructure.

Applications of Powder Coating

• Architectural and interior design
• Electrical and control panel fabrication
• Furniture and lighting fixtures
• Industrial machinery and parts
• Automobile and transportation components
• Agricultural and construction equipment
• Signage, fencing, gates, and railings
Whether you're protecting a warehouse racking system or enhancing the look of your steel balcony railings, powder coating delivers both aesthetics and endurance.

How Our Process Works

• 1. Surface Preparation::
  Rust, scale, oil, and dirt are removed through sandblasting or pickling for better adhesion
• 2. Electrostatic Application:
  Charged powder is sprayed onto grounded metal parts
• 3. Curing in Oven:
  Components are baked at 180–200°C to melt, bond, and solidify the coating
• 4. Quality Control:
  Thickness, gloss level, adhesion, and colour consistency are tested before dispatch
We support custom powder thickness (usually 60–120 microns) based on environmental conditions and service life requirements.
