Murudeshwara Trust
Blasting and thermal spray aluminium on the statue and the gopuram, which stand in the salt air of the Karnataka coast.
Abrasive Blasting in Mangaluru
Our blasting teams travel approximately 350 km from Bengaluru with their own compressors and blast hoppers.
- Blasting to ISO 8501-1 Sa 2½
- Copper slag, steel grit and aluminium oxide
- Teams from Bengaluru, about 350 km
Blasting on the Mangaluru Coast
Steel at New Mangalore Port, around the MRPL refinery area and along the coastal belt up to Udupi stands in a marine atmosphere. Salt-laden air settles on it throughout the year, and chlorides collect in pits under rust and old paint.
The heavy south-west monsoon, from roughly June to September, brings sustained rain and high humidity, and blasted steel can show flash rust within hours in such air. We plan site blasting around dry spells and prime or metal spray each section on the same day.
Blasting removes rust, scale and old coating, but soluble salt can remain in deep pits. Where your specification calls for washing or a salt check on old coastal steel, please mention this at the time of enquiry so that it can be built into the sequence.
Steel We Blast in and Around Mangaluru
Port and terminal structures, New Mangalore Port
Jetty steelwork, conveyor galleries, tanks and pipe racks exposed to salt spray are stripped back to bare metal where paint has failed.
Refining and petrochemicals, MRPL area and Mangalore SEZ
Tank shells, pipe supports, process structures and chimneys that stand in a marine and chemical atmosphere.
Shipbuilding and ship repair yards
Fabricated blocks, deck steel and repair sections that require blasting to bare metal before they are painted.
Fertilisers and chemicals, Panambur and Baikampady
Ducts, vessels, stacks and structural steel where chemical fumes add to the salt air.
Blasting Projects in Mangaluru
A supervised team travels approximately 350 km by road from our Bengaluru units with compressors, blast hoppers, hoses and test instruments. Port, refinery and SEZ sites set their own gate, permit and safety rules, and the team works within them. Shifts are organised so that a shutdown window is used fully.
Blasting is carried out at your site or, for parts that can be transported, at our facilities in Bengaluru, away from coastal weather. The abrasive is selected from steel grit, copper slag and aluminium oxide to suit the specification, and the blast grade and surface profile are recorded for every project.
- Air compressors
- 15 units
- Blast hoppers and hose sets
- 15 sets
- Air receivers
- 6 units
- Abrasives
- Steel grit, copper slag, aluminium oxide
- Blast grades
- Sa 1 to Sa 3 to ISO 8501-1
- Checks
- Surface profile gauge, psychrometer

Frequently Asked Questions
Can you blast inside New Mangalore Port or a refinery area?
We can work wherever the site permits our team to enter. Port, refinery and SEZ sites set their own passes, permits and safety rules, and we work within them. Please share the area, the access arrangements and your shutdown window when you make your enquiry.
Can blasting be carried out during the monsoon?
Blasting in heavy rain is not practical, and coating over wet or flash-rusted steel fails early. We plan site work for dry spells and agree weather cover with you. Parts that can be transported may be blasted in our Bengaluru booths regardless of the weather at Mangaluru.
Does blasting remove salt from old coastal steel?
Blasting removes rust, scale and old coating, but chlorides can remain in deep pits. If your specification requires washing or a salt check, we plan it into the sequence, and the blasted steel is coated on the same day.
Can corroded thin plate be blasted?
We blast steel from 2 mm thickness upwards. Thinner or heavily wasted plate can warp under the blast, so we inspect it first and advise on how it should be prepared.
