The widely known SPIROsol helically corrugated steel pipes have been in trouble-free use for over 100 years. The pipes are light weight and can be installed quickly and easily.
SPIROsol can be used as storm water tanks. They are supplied in diameters ranging from Ø300 through Ø2800mm in lengths till 12m. They can be coupled by means of a SPIfix coupler or flanges. Because of the light, flexible constructions, no foundation is needed and simple ground consolidation is sufficient. It is an alternative to concrete structures.
SPIROsol pipes are made out of galvanised steel, but can also be provided with a Duflex 240 coating. Standard fittings such as flanges, manholes, inlets and outlets are offered for the full range.
