What LORO does

LOROWERK K.H. Vahlbrauk GmbH & Co. KG, operating under the brand LORO, is a German family-owned manufacturer of steel drainage pipe systems for buildings. Founded more than 60 years ago and headquartered in Bad Gandersheim, Germany, the company designs, produces, and distributes the LORO-X drainage system built around a proprietary two-chamber push-fit socket connection (Zweikammern-Steckmuffenverbindung). The product range spans pipe diameters from DN 32 to DN 300 and includes specialized variants for parapet, flat roof, balcony, and cascade drainage applications, with the company having manufactured more than 100 million push-fit connections over its operating history.

The company's technical differentiation rests on its proprietary two-chamber push-fit socket system, the DUPLEX corrosion protection, the VARIOFIT retention system, and compliance with the DIN EN 1123 standard, supplemented by DIBt approval, LGA certification, and Baustoffklasse A1 non-combustible classification. These features are targeted at architects, building planners, installers, and developers across residential, commercial, industrial, and infrastructure projects including hotels, hospitals, schools, parking structures, bridges, and shipbuilding.

LORO operates a direct hardware sales model with quote-based pricing, distributing through 15 regional sales areas within Germany and exporting to more than 25 countries across Europe, the Americas, the Middle East, and Asia-Pacific. The company remains under family ownership with no external investors; managing directors are Wolfgang Vahlbrauk (Dipl.-Ing.) and Carlo Vahlbrauk (Dipl.-Ök.).
