Perma Stack®

Perma Stack®

RPC offers custom designed, chemically and structurally engineered ventilation and waste gas stacks - Perma Stack®.

RPC designs, manufactures, and if required will install, a comprehensive range of Glass Reinforced Plastic (GRP) ventilation and waste gas exhaust stacks - Perma Stack®.

Chemically and structurally engineered with the optimal balance of resin and glass to resist a wide range of acids, alkalis solvents and corrosive fumes, Perma Stack® is resistant to the damaging effects of Australia’s most demanding climatic conditions.

In addition to their resistance to corrosion, pitting and scaling, Perma Stack® are immune to virtually all bacteriological corrosion, will not rust, and do not require any form of cathodic protection.
In accordance with local wind loading designation, geology and topography Perma Stack® may be free standing, guyed or supported by a lattice steel frame.

RPC has successfully designed, manufactured and installed Perma Stack® from 10m to in excess of 100m in height.

Perma Stack® is designed by RPC’s professionally qualified, experienced engineering team and custom fabrication is done by RPC’s highly competent tradespeople in their purpose built factories. This ensures Perma Stack® will have a long life with minimal requirement for maintenance.
