About GTR

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.

Services

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.

Why Choose Us

What our customers rely on

Frame work leaves little room for approximation. This is what we hold ourselves to on every order.

01

Tolerances you can build on

Every frame is measured against the original drawing before it's cleared to ship, not sampled at random.

02

One workshop, one accountable team

Design, welding, and finishing happen under one roof, so nothing gets lost between subcontractors.

03

Realistic delivery dates

We quote lead times based on our actual floor capacity, not a sales estimate we later have to walk back.

04

Single units or production runs

Our line handles a one-off prototype frame and a 500-unit series with the same process discipline.

05

Materials sourced for the application

We match steel grade, wall thickness, and coating to the load and environment, not the cheapest stock option.

06

Direct engineering contact

Questions about a drawing go to the engineer who reviewed it, not through a call centre queue.
