Essar Power, Surat
A chimney aluminized in place at the power plant, without dismantling it. This is the method we offer for chimneys and ducts at power plants in the state.
Thermal Spray Coating in Ahmedabad
Our teams arc spray zinc and aluminium onto blasted steel where it stands, with their own spray sets and compressors.
- Zinc, aluminium and Zn-Al 85/15
- 15 arc spray sets
- Site teams with their own equipment
Thermal Spray Across Gujarat
Thermal spray melts wire or powder and sprays it onto steel. Zinc and aluminium metallizing is well suited to site work, because a team needs only power and access. Structures too large for a galvanizing bath, or already installed, can be blasted and sprayed in place without heat distortion.
Around Ahmedabad this mainly means chemical plant structures, tank shells and pipe racks, together with chimneys and ducts at power plants. Metal spray requires no curing, so the full thickness is applied in one shift, which suits a shutdown window.
Applications Around Ahmedabad
Power plants across Gujarat
Chimneys, boiler structures and ducts aluminized in place. Arc spray sets need only electrical power and access to the steel.
Chemical, dye and pharma units, Vatva and Naroda GIDC
Steel that cannot go to a galvanizing bath: installed tanks, pipe racks and frames, zinc sprayed in place and sealed.
Refineries, petrochemicals and the Dahej and Bharuch coast
Aluminium on tanks, vessels and process steel in salt and chemical air. Mythri Metallizing is an Engineers India Ltd approved vendor for thermal spray aluminium coating (TSAC).
Engineering plants with worn parts
Worn shafts and journals are rebuilt by metallizing and machined back to size.
Thermal Spray for Ahmedabad Plants
For structures, a team travels with arc spray sets, compressors and blasting equipment. Steel is blasted, sprayed and sealed section by section, so that no blasted steel is left to rust, and thickness is tested before release.

Work in Gujarat
Essar Projects, Hazira
A zinc metallizing project at Hazira, in south Gujarat, that ran for 100 days with a team of 20 on site.
Frequently Asked Questions
Can you aluminize a chimney at our power plant without taking it down?
Yes. Chimneys are usually treated in situ, with blasting and spraying carried out from scaffolding or other access around the stack, normally in a planned shutdown.
What must our site provide for thermal spray?
Our teams bring spray sets, compressors and blasting equipment. Arc spray needs electrical power and access to the steel. Flame spray needs no electrical supply, so it suits repairs, small areas and places without power.
What thickness do you apply, and how is it checked?
Our standard for zinc and aluminium is 175–200 µm, and up to about 500 µm is possible. Thickness is measured with a calibrated gauge before release, and pull-off adhesion is tested.
