The GEOCAST® calenders are mainly designed and built according to the highest requirements of the geomembrane multi-extrusion coating field. 
Monobloc strong rolls, thickness control high precision, lowest T° deviation across the full width of the rolls are the basic performances required today from the high quality geomembranes industry involved in the production of roofing and waterproofing synthetic membranes. 
The multi-extrusion coating technology is able to provide with two extruders PVC or TPO film to be properly calendered with GEOCAST® at high pressure values and superior linear precision inserting a synthetic PET or glass fiber net in the package. The GEOCAST® calenders, thank to the most advanced technology for 
steel roll manufacturing (ROLLBLOCK®) and the hydraulic positioning system HYDROGAP® and force control system HYDRONIP® are the status of the most available calendering technology.
