It all started with a simple idea: Huge quantities of seamless steel tubes seemed to be unsalable in Italy in 1977, but the owner of GERO Gelsenkirchener Rohrhandels GmbH bought the whole stock and set off to sell them in Germany. In no time, he was able to sell more than 2,000 t. That was the start of GERO Gelsenkirchener Rohrhandelsgesellschaft mbH in steel tube trading. Today, the company is an internationally respected specialist for seamless steel tubes.
