Structural Roof Curbs

Structural curbs are individually designed to span the existing bar joist at the base, transitioning to match specific unit dimensions at the top.  Heavy gauge galvanized steel (actual thickness determined by unit weight) and full height internal dividers add the strength necessary to support the unit without additional framing.  P.E. stamps are available for all 50 states if needed.

Our standard curbs are built to use on both insulated and non-insulated roof decks. Insulated curbs have fully mitered and welded corners, and are mainly used for small equipment such as exhaust fans. Non-Insulated curbs are designed for larger HVAC units on insulated roof decks, and can be factory welded or shipped un-assembled.
