Mechanical Rooftop Support Systems

Installing mechanical and electrical equipment to the roof of commercial buildings is a smart solution for maximizing indoor building space, but it comes with some specific challenges. The Unistrut Midwest team is familiar with the demands of mechanical rooftop support systems and is ready to partner with you to bring you the application you need.

Unipier rooftop supports are ideal for Unistrut crossovers, allowing easy access over pipes and conduit.

All mechanical rooftop supports should be constructed using materials that can sustain relevant environmental conditions, from harsh weather, heat, or cold, to extensive moisture or corrosive environments. Supports should also provide a stable base than can adequately distribute the equipment load on the roof membrane or structure.

Unistrut is an ideal product for rooftop piping, duct work, and mechanical equipment supports. With a wide range of rooftop products, Unistrut channel profiles, and weather-resistant finishes, Unistrut has the solution to any rooftop challenge. And with Unistrut’s inherent ability to be assembled ahead of time off-site, prefabricated rooftop walkways can be delivered and easily installed on-site.
