Precision Equipments, Chennai
A component-scale aluminizing project for a Chennai company, carried out by a team of five.
Thermal Spray Coating in Chennai
Our teams arc spray zinc and aluminium onto steel at your Chennai plant.
- Arc and flame spray at site
- Site teams with their own equipment
- Zinc, aluminium, Zn-Al 85/15
Metallizing Steel Where It Stands
Structures such as chimneys, ducts, tanks and girders are blasted and then arc sprayed with zinc or aluminium by a team that travels from Bengaluru with its own compressors and arc spray sets. The team requires only power and access. Flame spray, which needs no electrical supply, covers repairs and awkward spots.
Where Thermal Spray Fits Around Chennai
Pump, valve and engineering works, Ambattur and Sriperumbudur
Worn shafts are rebuilt by metallizing and machined back to size.
Power and process plants, Tamil Nadu
Chimneys, ducts and boiler structures receive aluminium metallizing.
Cement and heavy process equipment, Ariyalur and beyond
Aluminium on kiln-area steel and equipment components. Aluminizing can reduce heat radiation from preheater structures, rotary kilns and TA ducts to a certain extent.
Plant maintenance teams
Flame spray repairs to damaged metallizing, site welds and pipe joints, with no electrical supply needed.
Thermal Spray Projects from Chennai
For a structure at your plant, the team blasts to Sa 2½ or Sa 3, sprays in overlapping passes to 175–200 µm and seals the coating. Thickness is gauged to IS 3203 and adhesion tested to ASTM D4541 before release. Metal spray needs no curing, so the full thickness is applied in one shift.

The chimney was aluminized while standing. It is the method our site teams bring to chimneys and ducts at Chennai plants.
Frequently Asked Questions
Which thermal spray processes can you run at our Chennai plant?
Arc spray and flame spray, with zinc, aluminium and zinc-aluminium wire, for steel structures and repairs.
Should arc spray or flame spray be used for a repair at site?
Arc spray deposits faster, so it suits large areas. Flame spray needs no electrical supply and handles small repairs, tight spaces and site welds better. We choose according to the area, the access and the power available.
What should be provided for a component coating enquiry?
We would appreciate the drawing, the base metal, how the part wears or fails, and the quantity. We confirm the coating and fixturing before the part travels to Bengaluru.
