L-finned tube

L-finned tubes are produced by continuous forming and welding, without addition of material, of hot-rolled strip pickled and oiled: in standard lengths of 6 metres and thicknesses of 1.5 to 2 mm. These L-finned tubes can have normal or offset fins of 15 and 20 mm. They are often used in metal joinery work (windows, doors, skylights and also in bodywork and urban furniture).
