Culvert pipes

Rotomon culvert pipes are made of high-quality polythene, strength class SN4 and SN8 according to standard SFS-EN ISO 9969. High quality is ensured by constant in-house inspection. The pipes are double-structured: the outer surface is corrugated and the inner surface smooth, which ensures excellent water flow. Owing to such a structure, the pipes are extremely tough, while being lightweight to handle.
