Manhole Covers are produced in compliance with the EN 124-1, EN 124-5 standards. In load testing, when deliberately stressed KIO lids will return to their initial shape and form. The same tests with extreme load show that instead cast-iron of covers break, whereas KIO products will move but do not fail, and continue to function effectively.
Through the continuous development of innovative solutions in the design and manufacture of composite covers and frames Polieco Group designed and built a new modular manhole, the KIO TRENCH: the cover is made using the material KinextTM while the frame is made of aluminum. This product is placed on top of a service channel in the concrete of a fairground, but the applications are possible: service areas, industrial areas, commercial areas, ports and docks.
KIO TRENCH is designed to fit trench widths of 40 cm or 80 cm
