JMD Company


is a leading manufacturer of custom fiberglass products for heating, air conditioning, industrial ventilation, exhaust, conduit, utility poles, and storage tanks.

Our filament wound fiberglass ducting is stronger and far superior to light-gauge steel and aluminum at a fraction of the weight. Fiberglass provides resistance to corrosive and high moisture environments. The finished product affords much longer-than service than ducting products made from aluminum or steel.


JMD Company's


manufacturing equipment can produce products up to 14 feet in diameter and over 40 feet long. Our in-house design and engineering team can assist with the selection, design, and installation of your specific product requirements.
