Steel Reinforced Corrugated Pipe coated with polyethylene (PE) layers, internal and external. The PE has a high level of surface bonding to the steel strips, thus enabling the bended profile to be performed in a cold forming waveform acting as the main supporting structure of the pipe.
Production using this hybrid technology combines polyethylene and steel resulting in steel imparting the strength and polyethylene coating imparting the protective layer and the "Wet Diameter” against corrosion and abrasion.
The combination of these two materials with the profile shape bring high ring stiffens SN8 up to SN16 and the corrosion resistance of the steel.
