For more than 40 years, Superior has been the leader in the design and production of quality metal trim products for the construction industry. Superior was the first to manufacture the Ventilation Expansion Screed and offer a labor saving solution to ceiling deflection with our Flex Track System. Over the years, more than 50 different products and configurations have been developed and are now available, offering virtually every size and shape practical for standard use. These, along with Superior's special custom design services offer an unlimited selection of plaster, drywall, stucco, EIFS and DEFS products to the architect, designer, or contractor for every functional requirement and design consideration.
