Our neutral PP cylinders have been designed to last longer and durably withstand friction from heavy pieces. They are tangible evidence of Progalvano technology. These cylinders (hexagonal or heptagonal) are manufactured by injection moulding and polyfusion. They slow down the clogging of holes as well as the wear and abrasion processes. They are equipped with a manual door and PVDF closing clips, and ensure excellent mechanical properties as well as optimal chemical resistance. Each cylinder is marked and identified by a serial number. We offer a complete range of circular and lamellar perforations. Thicknesses available: 12,15 and 20mm.
