Description:
RPC’s GRP vent shafts, PermaVent® and GRP waste gas stacks, PermaStack are chemically and structurally engineered with the optimal balance of resin and glass fibre for resistance to a wide range of acids, alkalis, solvents and corrosive fumes.
In addition to their resistance to corrosion, pitting and scaling, they are immune to virtually all bacteriological corrosion, will not rust and do not require any form of cathodic protection. A surface coating applied during manufacture ensures a long life even in Australia’s most demanding climatic conditions. Once installed, PermaVent® and PermaStack are virtually maintenance free. RPC has successfully installed PermaStack from 10m to in-excess-of 100m in height.
