about us

In 1989, Kingsbridge Metal Inc., was established in Carrollton, Ga., on the foundation of offering high quality HVAC sheet metal products with a family touch. This personal approach has helped make KBM one of the leading manufacturers in the southeast.

Today, born from the blueprints of Kingbridge Metal Inc., Spiral King has become a leader in providing high quality Spiral duct products across the region.  Although the names are different, our goals are still the same; to meet all of your business needs with honesty and integrity at the forefront of everything we do.
