Product Overview
The Z-section is cold formed from high strength strip into a symmetrical profile, which lines the neutral axes of neighbouring piles up so the wall acts as a single deep beam. That gives the highest bending capacity per ton of steel of any sheet pile shape, so a lighter wall does the same job. The hook type interlock is driven against a guide frame to hold verticality, which is what long piles in deep water need.
