Manhole covers

KIO manhole covers set new standards in modern infrastructure. They are made from a high-performance composite material that has proven itself in Formula 1 and aviation. They are lightweight and therefore ergonomically easy to handle. KIO manhole covers are extremely durable and resilient. They withstand the harshest conditions, are chemical-resistant, corrosion-free, and UV-resistant. Whether in urban environments, industrial areas, or high-traffic zones—KIO manhole covers offer maximum reliability. With load classes ranging from A15 to F900 in accordance with EN 124-1 and EN 124-5, they guarantee the highest level of safety and flexibility for every project. For applications in tunnels, airports, train stations, exhibition centers, and similar facilities, we manufacture the flame-retardant “c” version. All these features make our KIO manhole covers the manhole covers of the future.
