Grunau Metals

Grunau Metals is able to design, fabricate, finish paint, and install any type of specialty metal. We've created everything from a 2-riser stair to reach roof-top equipment to an 11-story launch gantry for NASA. From multi-million dollar projects down to walk-in work for a residential handrail, if you can dream it, we have the minds and tools to create it.

Grunau's own Metals Shop fabricates, sandblasts, and paints your custom designs while our field crews will install projects to your specifications.

The fire protection system at the Flint Hills Resources Milwaukee Terminal offered some unique challenges to Grunau, and they performed exceptionally at every turn. The site restrictions and customer expectations could not have been any higher, and the Grunau personnel rose above the restrictions and led the effort to complete, commission, and train the Owner on a system that they were not familiar with. Performance specifications can often prove difficult with subcontractors that are not familiar with a design-build firm, but Grunau provided excellent services and delivered on their promise. It was a pleasure to have the opportunity to work with Eric Radke and the good people at Grunau.”
