HBU Hartstein- und Baustoffunion GmbH is a Private limited company (Ltd.) registered in Germany under HRB 207111 Hannover, and its current status with Handelsregister (Commercial Register) is active. The company was incorporated on 18 July 1990 and lists its registered address as Hannover, Germany. 1 shareholder is on record for HBU Hartstein- und Baustoffunion GmbH, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Handelsregister (Commercial Register) and was last updated on 19 October 2026.

Shareholders

Two of the 5 officer records shown for HBU Hartstein- und Baustoffunion GmbH are current appointments, filed with Handelsregister (Commercial Register). Mirko Langehein (appointed 2011-05-18) and Mathias Gesang both serve as Geschäftsführer (managing director). The remaining 3 records shown (Jörg Kiehne, Tim Kettemann and 1 other) are former appointments that have since been resigned.

The register reports 7 officers in total, including past appointments, though only the 5 most relevant records are shown here.

Management authority at HBU Hartstein- und Baustoffunion GmbH sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.

The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
