Rooftop HVAC Support Structures

Custom steel dunnage frames, platforms and curbs that carry large rooftop air conditioning units on shopping centers and commercial buildings.

Built for heavy equipment, Florida weather and tight schedules.

Large commercial rooftop units weigh thousands of pounds and have to sit level, secure and supported for decades. We fabricate the steel structures that hold them, built to your engineer’s stamped drawings and the exact unit footprint.

We model each structure before fabrication, so contractors know exactly what is arriving on site and how it sets on the roof.

Common Questions

Need a fast answer? Call us at (651) 529-7989.

Do you need stamped drawings?

Structures that carry rooftop equipment are normally built to drawings from a licensed engineer. Send them with your request. If you do not have them yet, tell us early and we will talk through next steps.

Can you match an existing structure?

Yes. Send photos and measurements of the existing support and the new unit’s data, and we will quote a matching or replacement structure.

How are the structures finished?

Galvanized or painted, depending on the project specification and location.
