Duct Systems of any size and shape have been designed to complement other components of a composites system.  Rectangular to round transitions for equipment connections, such as fans and pumps, hoods for fume removal, chutes, and flumes are examples of the many specially made components needed to complete a composites project.  Like other composite structures from Ershigs, these components require little maintenance and never need painting, lowering lifetime cost of ownership.

Ershigs designs, manufactures, fabricates and installs corrosion-resistant products made of Fiberglass Reinforced Plastics (FRP) such as process and effluent piping, abrasion resistant piping, storage and process vessels, stacks and chimney liners, duct systems and valves.
