PAL / PAU - Omega sections

Omega sections are quite well suited for the execution of continuous walls that have a limited height.

Their shape has been optimized in order to achieve an excellent ratio section modulus / mass, with section modulus up to 1 100 cm3/m, and thicknesses from 3.0 up to 8.0 mm.

Omega sections are assigned to a special category because they are neither Z-piles, nor U-piles. They have a continuous web so that shear stresses can be transmitted through the webs.

Installation can be quite fast due to the width of up to 921 mm of a single pile.

Omega sections can be delivered in two different forms, with handling holes.

Note that Omega sections can only be threaded with specific series of cold formed sections (different interlock shapes).

The PAL 27 series is well suited for re-use.
