Frame structures built to hold their shape, under load, for decades.
GTR Beteiligungsgesellschaft mbH designs and manufactures custom steel and metal frame constructions for machinery, industrial equipment, and structural applications — engineered in Lauingen (Donau) and delivered across Germany.
Rahmenfertigung is our entire craft, not one line among many.
GTR Beteiligungsgesellschaft mbH is a frame manufacturing company based in Lauingen (Donau), Germany. We specialise exclusively in the design, fabrication, and finishing of steel and metal frame structures — from single custom units to ongoing production runs for industrial partners.
Because frame construction is the only thing we build, every process on our floor — cutting, jigging, welding, finishing — is set up around getting corners, tolerances, and load paths right the first time. That focus is what our customers come back for.

Frame manufacturing, end to end
Six connected capabilities that take a frame from drawing to delivery, in-house.
Custom Frame Fabrication
One-off and small-batch frames built to your drawings, load specification, and mounting requirements.
CAD Design & Engineering
In-house structural drawings, tolerance planning, and design-for-manufacture review before a single cut is made.
Steel & Metal Assembly
Precision jigging and assembly of multi-piece frame sections to hold true alignment across the full structure.
Welding & Joining
MIG, TIG, and spot welding carried out by certified welders, with joint inspection built into every stage.
Surface Finishing & Coating
Powder coating, galvanising, and primer treatments selected for the frame's operating environment.
Quality Assurance & Testing
Dimensional checks and load testing against DIN specifications before any frame leaves our facility.
What our customers rely on
Frame work leaves little room for approximation. This is what we hold ourselves to on every order.
Tolerances you can build on
Every frame is measured against the original drawing before it's cleared to ship, not sampled at random.
One workshop, one accountable team
Design, welding, and finishing happen under one roof, so nothing gets lost between subcontractors.
Realistic delivery dates
We quote lead times based on our actual floor capacity, not a sales estimate we later have to walk back.
Single units or production runs
Our line handles a one-off prototype frame and a 500-unit series with the same process discipline.
Materials sourced for the application
We match steel grade, wall thickness, and coating to the load and environment, not the cheapest stock option.
Direct engineering contact
Questions about a drawing go to the engineer who reviewed it, not through a call centre queue.
Tell us about the frame you need
Send us your drawings, specifications, or just a rough description of the application — we'll come back with a clear quote and timeline.
