Prakash Asphaltings & Toll Highways, Ratlam
Steel girders of a railway bridge on State Highway 27, Madhya Pradesh, were metallized with aluminium and finished with a three-coat paint system.
Industrial Spray Painting Services
Mythri Metallizing primes and paints the steel that we blast, so that a single team is responsible for the entire project.
- Primer to finish coat
- Airless and compressed-air spray
- DFT checked on every coat
Durable Paint Begins with the Steel
A paint system is only as good as the surface beneath it and the thickness to which it is built. Because we blast the steel ourselves, primer is applied to clean, profiled steel within hours, before it can rust again.
Each coat is sprayed to its specified thickness and checked dry with a coating thickness gauge before the next is applied. Work at our facilities is carried out in spray booths, protected from dust and weather, and structures that cannot travel are painted on site.
Unit I handles blasting, metallizing and primer application, while Unit III handles painting operations: sanding, putty application, primer application and the final finishing coats.
We purchase primers and paints from certified industrial paint manufacturers, and apply the system specified by your consultant or paint supplier, or recommend one suited to the environment.
What We Paint
New Fabrications
Structures and equipment are blasted, primed and finished before they leave for site.
Machine-Tool Castings and Bases
Primed after blasting and stress relieving, ready for machining and final painting.
Paint over Metallizing
Paint over sealed zinc or aluminium provides colour and additional life in aggressive environments.
Maintenance Painting on Site
Blasting and repainting of plant structures during a shutdown.

Our Painting Procedure
Blast
The steel is blasted to the grade that the paint system requires.
Prime
Primer is applied on the same day, before the blasted steel can rust.
Build the System
Intermediate and finish coats follow within the recoat times given on the data sheet.
Inspect and Record
DFT is measured on every coat and recorded in the project report.
Applications
Industrial painting is one of our five core services, alongside blasting, primer application, stress relieving and metallizing.
- Machine-tool castings and bases
- Structural steel and trusses
- Tanks and vessels
- Bridge girders over metallizing
- Plant equipment and pipe racks
- Transformer tanks

Frequently Asked Questions
Can you apply a system specified by our paint supplier?
Yes. We follow the surface preparation, coat sequence, thicknesses and recoat times given on the paint data sheet or in your specification.
Is painting carried out on site?
Yes. Our teams take airless and compressed-air spray equipment to site and paint structures in place, usually immediately after blasting.
What is a duplex system?
A duplex system is paint applied over thermal spray zinc or aluminium. The metal coating protects the steel and the paint protects the metal coating, giving a longer life than either alone.
Are DFT reports provided?
Yes. Dry film thickness is measured on every coat and recorded in the project report.
