Method to produce radiating tubes, and relative radiating tubes, for radiancy heating lines for premises (12), said radiating tubes defining a forced-circulation circuit of a thermal carrier gas fluid for heating purposes, said radiating tubes being formed by shaping from an aluminium-coated steel strip, said aluminium-coated steel strip being subjected, during one step of the production cycle of the radiating tube (10), to at least a heat treatment step made at a temperature above the melting temperature of aluminium, said heat treatment having the function of improving the intrinsic characteristics of heat emissivity of said tubes (10). |
