IFR's, Internal Floating Roofs

Internal floating roofs made of FRP have an excellent chemical resistance. 

Since 1991 Sjaak Riemens is involved in the design, engineering and QA/QC of IFR's made of FRP. There are mainly two types of FRP IFR's: roofs made of prefabricated panels and roofs that are completely fabricated inside the tank.
