About Curbco

In 1977 a small custom sheet metal shop, known as Spring Branch Sheet Metal (SBSM) opened its doors with seven employees. After years of producing sheet metal products ranging from decorative copper awnings to kitchen hoods, SBSM found a niche in the market of rooftop HVAC accessories. In 1983, the name Curbco was trademarked and the evolution began from local sheet metal shop to a nationally recognized supplier throughout the HVAC industry.


For decades we have been revolutionizing the HVAC retrofit business, and we don’t think we should take our foot of the gas now! Would it help you to have instant access to curb adapter pricing (including freight) and submittal drawings, that your customer can approve with their phone? Well now YOU CAN!  Get what you need from Curbco...24/7...heck, Anytime!


Curbco has built a reputation as an industry leader in Quick-Turn Production and Service in the Planned and Unplanned HVAC retrofit business. For this distinction we thank our Loyal Customers and our diversely talented team with backgrounds in HVAC Equipment Distribution, Mechanical Engineering Design, Sheet Metal Fabrication and Business Management.
