Built on 40 years of engineering heritage — now dedicated exclusively to radiator fin manufacturing.
A fully automatic 65-metre production line ensures every fin is formed, welded, and tested with zero manual variation. Consistent quality across every batch, every order.
Every single assembly undergoes hydraulic leak testing before dispatch — not sampling, every unit. Zero leakage guarantee on all radiators supplied.
Servo-controlled cutting holds every fin to ±1 mm of your specified length. Consistent dimensions mean faster assembly at your factory and zero rework on fit-up.
