HZM Combined Wall System
The HZ Combined Wall System was introduced by Arbed in 1972. As with all of their sheet pile sections, Arbed, Arcelor/ArcelorMittal continued to develop the best product possible and in the late 2000s came up with the current system. A connector is threaded at the end of the flange of the HZM king pile. The intermediary AZ piles are then threaded onto the connectors between two HZM piles. There are three different depths of HZM piles, with four thicknesses in each depth, giving a total of twelve different beams to choose from. The HZM system can be used with single beams, double beams, or continuous beams. All of these options, combined with the various choices for the AZ intermediary piles, offer hundreds of combinations to choose from.
