Abrasive Blasting in Chennai
Our blasting teams travel from Bengaluru to plants across Chennai with their own compressors, blast pots and test equipment, and prepare steel to the grade that your coating specification requires.
- Blasting to ISO 8501-1 Sa 2½
- Site teams with own equipment
- Tamil Nadu projects since 2012
Coating Life on the Chennai Coast
Steel along the Chennai coast, from the Ennore port belt to the Manali petrochemical cluster, sits in a marine industrial atmosphere. Airborne chlorides settle into pits and under old coatings, and any salt left on the surface before coating will push the new system off the steel within a few seasons.
We therefore treat blasting as the most important stage of a coating project in this region. Steel is blasted to Sa 2½, near-white metal, or to Sa 3 where the specification asks for it, and coated the same day before flash rust can form in the humid air.
For structures that need the longest life in this environment, blasting is usually followed by thermal spray aluminium or zinc and a sealer, rather than paint alone.
Plants We Support in and Around Chennai
Ports and terminals, Ennore
Cranes, conveyor galleries, tanks and pipe racks exposed to sea air and spray.
Refining and petrochemicals, Manali
Tank shells, pipe supports, chimneys and process structures in a chemical atmosphere.
Automotive and engineering, Sriperumbudur
Machine bases, fixtures and fabricated assemblies that need clean, profiled surfaces before painting.
Cement and power across Tamil Nadu
Kiln-area structures, preheater towers, ducts and boiler chimneys.
Chennai Blasting Projects
For work at your plant, a supervised team travels from our Bengaluru units with blasting and coating equipment, sets up within your safety permits and works in shifts so a shutdown window is used fully. Parts that can be transported may instead be delivered to our facilities in Bengaluru, at Peenya or Dabaspet, and are returned blasted and coated.
Every project concludes with a record of the blast grade achieved, the coating thickness and the adhesion results.
- Air compressors
- 15 units
- Blasting hoppers and hose sets
- 15 sets
- Thermal spray arc rectifiers and guns
- 15 sets
- Airless spray equipment
- 5 sets
- Abrasives
- Steel grit, copper slag, aluminium oxide

Frequently Asked Questions
Does your team attend our plant in Chennai, or should we send the parts?
Both arrangements are available. Our teams travel to Chennai and the surrounding industrial areas with their own equipment for structures and installed plant. Smaller parts may be sent to our facilities in Bengaluru, about 350 km away, and returned coated.
What blast grade should we specify near the coast?
For coatings in a marine or chemical atmosphere we recommend Sa 2½ (near-white metal) as the minimum, and Sa 3 for thermal spray aluminium in the most aggressive service. We confirm the grade against your coating manufacturer or consultant specification.
Which abrasive do you use?
The abrasive is selected for the project from steel grit, copper slag and aluminium oxide, according to the rust condition, the profile required and the specification. Copper slag is commonly used for large structures on site.
Can the steel be coated after blasting?
Yes. We follow blasting with thermal spray zinc or aluminium, primer and paint systems, so the surface is coated before it can rust again.
