Manufacturing of stove accessories, stoves and components made of natural stone and ceramics
CB-tec GmbH, headquartered in Ungerhausen in the Allgäu region, was founded in 2013 and employs over 140 staff on a production and warehouse area of 15.000 m². The company manufactures more than 1,000 accessory products for stove and fireplace construction, including ventilation grilles, spark protection panels and air dampers, as well as complete stoves and fireplace inserts, which are predominantly produced in its own production facilities. In the CB Manufaktur, natural stone, ceramic materials, sintered ceramic, quartz, raw steel and glass are processed into components such as fire tables, stove systems and kitchen worktops made from over 400 materials. A stock of around 8,000 raw slabs ensures high flexibility and fast delivery times. Fireplace inserts and stoves are manufactured in the Allgäu by the subsidiary CB Kollinger Metallbau GmbH on modern semi- and fully automated laser cutting centres, bending robots and welding robot systems. With the subsidiary CB Projekt, a construction service is offered covering everything from planning and surveying through to final installation of natural stone and ceramic work. CB TEC supplies around 5,000 customers across industries in Germany and Europe – from stove construction to kitchen studios, shopfitting and gastronomy through to construction and real estate projects.
