There is provided a reinforced converter body, especially one useful as a 'light-off' converter in a gas treating system for treating exhaust gas from internal combustion engines. The invention utilizes corrugated and flat thin metal strips in alternating relation. Reinforcement is enhanced by the use of thin metal strips of a stronger alloy for at least a part of the thin metal strips.
