Competitive Advantage:

  1. We have more than 10,000 square meters workshop, including 7  finning machines, daily capacity up to 5,000 Meters.
  2. The finning machines are designed and assembled by ourselves and we can offer you finning machines and all accessories etc...
  3. This method of manufacturing overlapped LL type enables us to place the finning on a very thin-walled tube with is particularly desirable when using high value alloys (titanium, stainless, copper, nickel).
  4. The LL TYPE fin tubes can withstand a temperature of up to 170°C and provide a better corrosion protection by overlapping the feet of the L shapes. Maximum operating temperature: 170°C
