About Kleinstahl

KLEIN Stahlvertrieb GmbH is an owner-managed steel trading company founded in 1991 and headquartered in Bornheim between Cologne and Bonn. The company supplies steel pipes and pipe accessories in all nominal sizes, welded and seamless, including boiler tubes to EN 10217-1 and EN 10216-1, threaded pipes to EN 10255, and unalloyed boiler tubes. A key focus is the supply of refrigeration pipes coated to AGI Q 151 for refrigeration, air conditioning and chilled water systems. In addition to storage and logistics, Kleinstahl offers processing services: sawing to fixed lengths, grooving and knurling (roll grooving), thread cutting, turning and milling, as well as corrosion protection through powder coating, galvanizing, interior and exterior coatings, PE or bitumen wrapping, cement mortar linings and blasting. Customers from refrigeration and air conditioning, heating technology, sprinkler systems and building services are supplied nationwide and in neighboring countries, primarily on construction sites. Its own vehicle fleet including crane trucks complements the delivery logistics.
