Why choose Liniar Flat Pile

Liniar’s flat pile can be used on installations where no great strength is required and where a clean straight line of piles is preferred.

Typically used for circular cell design applications, flat sheet pile is a proven technology that’s used on many projects. While these sheet piles offer much less beam strength than Z piles, the sections use a thumb and finger to generate significant pull strength to counter the hoop stress applied to them.

Liniar’s flat piles are used almost exclusively for building large, filled cellular structures. Flat sheets must provide some ability to ‘swing’ between sheets so that a circle can be closed.

Flat pile is used in the damming of peat bogs, as a heavy-duty edging or raised bed retaining profile.
