 The company has been producing thin-wall ALZN tubes since 1986. Cold-rolled steel tubes were added to our product selection in 1993. Our ISO 9001 system ensures that the tubes are of high quality. Furthermore, our product development and testing laboratory conducts continuous tests on Fenno exhausts.Fenno standard tubes (dimensions/weights) Standard tube materials
Tubes from other steel grades, e.g. galvanised, aluminised or constructional steel may also be produced upon request.  ALZN steel tubesALZN steel tubes combine the best qualities of steel, aluminium and zinc. They resist corrosion as well as aluminium, and endure mechanical and thermal stress as well as steel. The zinc provides great cathodic protection for edges and cross cuts. The weldability of ALZN tubes is excellent compared to hot-galvanised tubes. ALZN tubes are ideal for extremely demanding conditions where rust may be a problem, and are suitable for a wide range of uses including heating pipes for greenhouses, ladders, aerials, etc. |
