ST Span 4 mm
The ST span is the modular structure between two towers composed of 6 and 12 m pipes and stiffened by elements called angles and rods.
The diameter sizing of the pipe depends of the machine flow and of the tolerated water speed.
The regular and symmetrical bend of the Otech span enables a uniform distribution of the stresses all along the structure.
The combination of the S275 high strength steel with the min. 3 mm thick line pipes and the angles, as well as the S355 steel rods guarantees an excellent resistance and durability.
The standard 4 mm thick span is composed of S275 12 m and 6 m pipes in high strength hot dip galvanized steel. This strong thickness guarantees a durability particularly increased in case of aggressive irrigation water.
