About Curbco

Our story begins in 1977, when Spring Branch Sheet Metal (SBSM) opened its doors as a Houston-based producer of all kinds of sheet metal products, from roof gutters to kitchen hoods, before finally finding its true niche in HVAC accessories. In those days, if you wanted to swap out an old rooftop HVAC package unit for another model, the difference in supply and return opening placement required a crew to rip out the old roof entirely and perform the new installation from scratch. The resulting crane time and labor costs were a huge burden on businesses — until we came along.

In 1983, SBSM trademarked its new name, Curbco, to feature our pioneering new product in the HVAC industry — the curb adaptor. Using sophisticated design and engineering techniques based on our comprehensive database of HVAC system makes and models, we were now able to custom-craft units that connected the existing rooftop openings to the intake and exhaust openings on any new HVAC package unit, regardless of the changes in design. This revolutionary idea slashed crane time and labor costs in half, bringing about the modern curb adaptor business as we know it.

Today Curbco enjoys national recognition as a leading supplier of curb adaptors, package equipment curbs, fan roof curbs, equipment supports, and metal building curbs for every major manufacturer in the HVAC industry. You couldn’t be in better hands if you need a precision-made solution for your rooftop curb needs. Go with one of the original grand masters in curb adaptor design and engineering — go Curbco!
