Mr. Hermann Krinn developed the corrugation 67,7×12,7mm in the year 1974, which will be used for small flat pipe arch and circle profiles until today.
corrugation: 67,7mm x 12,7mm
plate thicknesses: 1,50mm – 4,00mm
span range: 0,60m – 2,40m
- M (flat pipe arch profiles)
- K (circle profiles)
Special constructive details such as elbows, penetrations, modeled curvatures, end walls etc. are available for all above mentioned profile lines.
Fields of application:
- flat pipe arch profiles for stream culverts under service roads
