Specialists in Coated Aluminium for HVAC and Industry
Aluminium fin stock is a critical component of heat exchangers in air conditioning, refrigeration and industrial cooling systems. It must meet demanding requirements for punching, forming, coating adhesion, corrosion resistance and consistent production performance, because fin stock quality directly affects fin forming, production efficiency and the long term reliability of the heat exchanger.
Our two coating lines, a colour coating line and a hydrophilic coating line, give closer control of surface preparation, coating application, curing and inspection, the parameters that decide coating uniformity, adhesion, colour consistency, hydrophilic behaviour and corrosion performance.
Each coil carries a unique batch number, so any query can be traced back quickly to its production record.
Types of Colour Coated and Hydrophilic Aluminium We Supply
Colour Coated Fin Stock
Fin stock with a colour coating for added surface protection and easy identification in HVAC and refrigeration coils.
Colour Coated Aluminium Coils
Coils with a factory applied colour coating for closures and other uses, which removes a separate painting stage from your process.
Colour Coated Aluminium Foils
Thin gauge coloured foil, including handicraft plain and colour foils for decorative products.
Applications of Colour Coated and Hydrophilic Aluminium Coils and Foils
Our coated coils, foils and fin stock are used across thermal management, closure and decorative industries, with suitability confirmed against each design and operating environment.
| Industry | Applications we supply |
|---|---|
| Air conditioning and HVAC | Heat exchangers for residential, commercial and industrial air conditioners, cooling coils and condenser coils |
| Refrigeration and cold storage | Commercial and industrial refrigeration and cold storage heat exchangers |
| Automotive and transportation | Thermal management in vehicles and transport equipment |

Frequently Asked Questions About Colour Coated and Hydrophilic Aluminium Coils and Foils
Which countries does Vishal Aluminium export hydrophilic fin stock to?
Vishal Aluminium has more than 15 years of export experience, with customers for fin stock in the USA, Canada and Europe.
What is aluminium fin stock?
Aluminium fin stock is aluminium strip or foil used to make the fins of heat exchangers, which increase the surface area for heat transfer in air conditioning, refrigeration and cooling equipment.
What is hydrophilic coated aluminium fin stock?
It has a surface coating that promotes water spreading, so condensate forms a thin film rather than droplets between closely spaced fins.
Does Vishal Aluminium have an in house hydrophilic coating line?
Yes. Vishal Aluminium's hydrophilic coating line produces blue and golden hydrophilic coating, a facility that is very rare in India.
Which alloys are available for fin stock?
Vishal Aluminium supplies fin stock in alloys 1050, 1100, 3003, 3004 and 8011, with other alloys available on request.
What thickness and width range is available?
Vishal Aluminium supplies fin stock from 0.065 mm to 0.50 mm thick and from 10 mm to 1600 mm wide, subject to alloy, temper and coating.
Does hydrophilic coating improve corrosion resistance?
A properly selected coating system can provide corrosion protection. Actual performance depends on the coating, coating weight, pretreatment, substrate and service environment, and is confirmed against agreed tests.
Is the material suitable for high speed fin punching presses?
Fin stock can be specified for high speed fin punching. Performance depends on the alloy, temper, thickness, coating, fin geometry, tooling, lubrication and press settings.
How is hydrophilic coating quality evaluated?
Through coating appearance and uniformity, adhesion, hydrophilic behaviour and other agreed tests, with methods and acceptance criteria confirmed before production.
Does the material comply with ASTM B209?
Where applicable, Vishal Aluminium can supply the aluminium substrate against ASTM B209. Coating performance is covered by its own agreed specification.
Can Vishal Aluminium deliver within 7 to 10 days?
For eligible regular customers with agreed long term commitments, Vishal Aluminium aims to deliver within 7 to 10 days, subject to stock, quantity, specification and destination.
Do you supply colour coated coils as well?
Yes. Vishal Aluminium supplies colour coated coils and foils alongside hydrophilic coated fin stock.
What are colour coated aluminium coils used for?
They are used for colour coated fin stock in HVAC systems, coloured closures and handicraft plain and colour foils.
Which colours can Vishal Aluminium supply?
Share the colour you need, and Vishal Aluminium will confirm what can be supplied for your order.
Why buy colour coated coil instead of painting parts?
Coated coil arrives ready to process, which removes a painting stage from your own production and gives a more even finish.
