Duct Dampers, Actuators & Expansion Joints

Pierce Steel has extensive experience fabricating unique ductwork.  We also make many custom-built accessories including dampers, actuators, and expansion joints. Dampers and actuators are used to control flow through ductwork or piping and can be manually or automatically operated. Our non-metallic expansion joints are flexible to allow for movement due to equipment vibration to limit noise and extend product life. They absorb movement due to vibration and thermal expansion and contraction. Expansion joints are ideal for use in HVAC ductwork, exhaust stacks, industrial piping, chiller piping, power generating, pulp and paper processing, pharmaceutical processing, oil and gas refining, water and wastewater treating
