Welcome to Thumm & Co. Staircases and Railings GmbH

With production of bolts for over 10,000 free-carrying staircases every year, we are without a doubt one of the leading manufacturers of load-bearing bolts and connection components for free-carrying staircases in Germany conforming to DIN 18069 (load-bearing bolt stairs). We maintain the required technical approvals necessary for all staircases (stone stairs, wooden stairs, newel stairs, acrylic glass stairs).

The ease with which our railings and banisters can be mounted makes them particularly suitable for customer installation. We supply system banisters for customer installation in stainless steel and gold-plated, antique copper and chrome-plated versions.


We are also well known for our technical approvals for the gluing of 3+3 cm granite with glass fibre cloth and epoxy resin.

Our bolts for free-carrying staircases are sold by more than 3,000 stonemason, staircase builder and joiner partners through Germany and Europe.
