HZ®-M King Piles

The HZ®-M king piles are stiff wide flange beams, with a width of 460 mm, a height up to 1100 mm, and flange thicknesses up to 40 mm, used in the HZ-M/AZ combined wall system.

The key feature of this special sheet pile is the milled groove at the edge of the flanges that allows threading specific hot rolled connectors on it. The development of this range was made specifically to match the higer requirements of the deep sea quay wall for JadeWeserPort in Wilhelmshaven, Germany, back in 2008. The HZ-M has been patented by ArcelorMittal.

Structurally, the HZ®-M king piles fulfill 2 different functions
  • as retaining members, the king piles resist horizontal loads resulting from earth and water pressures,
  • as bearing piles, the king piles transfer high vertical loads from the superstructure, i.e. crane rails, building foundations, etc, to the ground.
The intermediate AZ® sheet piles have a closing function, retaining earth and water, but they transfer most of the loads to the king piles. Infill sheet piles can be exclusively a pair of light AZ sections because they have sufficient flexibility to adapt to the driving tolerances of a combined wall system.

The HZ-M and their connectors are available in high strength steel grades according to EN10248, ASTM A572 and ASTM A690.
