Electricity insulation - Import export

BENEFITS of composite manhole covers: theft prevention, noise reduction, resistance, lightness, electric insulation, resistance to corrosion. FRP manhole covers of M.M. are manufactured in accordance with the EN 124:2015: A15 (test load 1.5 ton) Areas which can only be used by pedestrians and pedal cyclists, B125 (test load 12.5 ton) Footways, pedestrian areas and comparable areas, car parking decks, C250 (test load 25 ton) For gully tops installed in the area of kerbside channels of roads which when measured from the kerb edge, extend a maximum of 0.5m into the carriageway and a maximum of 0.2m into the footway. D400 (test load 40 ton) Carriageways of roads including pedestrian streets, hard shoulders and parking areas, for all types of road vehicles.

FRP gratings are made of polyester or vinylester resin, fibreglass and inorganic halogen-free fillers that provide the self-extinguishing properties. They are supplied with anti-slip surfaces of varying levels, classified and certified according to the DIN 51130 standard (determination of the anti-slip properties). Gratings are certified as durable product whose mechanical performance is not affected by the cycles of hot/cold e humidity exposure in accordance with the UNI EN ISO 9142 standard; they have also passed the aging resistance test with cycles of UV exposure in accordance with the ASTM G154 standard; they are supplied with self-extinguishing properties in accordance with EN13501, ASTM E84, ASTM D635, DIN 4102, NFP 92-507 standards. They are tested and classified as excellent electrical insulators.
