AZ® sections

Z-type sheet piles are the preferred choice for permanent applications. Among the essential characteristics of Z-shaped sheet piles are the continuous form of the web and the specific location of the interlock symmetrically on both sides of the neutral axis. These two attributes have a positive influence on the section modulus. The AZ® series combine a section with extraordinary characteristics with the quality-proven Larssen interlock. Z-shaped sheet piles present the following advantages
  • extremely competitive section modulus/mass relation,
  • lighter than U-piles when comparing sections with equivalent properties,
  • increased inertia and thus reduced deflection allowing the choice of high yield strength steels for the most economical solution,
  • large width resulting in high installation performance and enhanced watertightness.

ArcelorMittal rolled the first AZ sheet piles beginning of the 1990's. It was at that time an awesome achievement to roll 600mm wide Z-type sheet piles with a Larssen type interlock. The AZ range was completed with the manufacturing in 1998 of the AZ48, the heaviest Z-section in the world (outperformed only in 2016 by a new AZ section).

A few years later, in 2004, we launched the AZ-700 wider and lighter sheet piles. Note that these piles are 700 mm wide. The first section was the AZ38-700, a monumental success. We were indeed the first manufacturer in the world able to roll such wide sections on a regular basis.

Since then, we observed a steady increase in demand for wider and lighter sheet piles. After extensive finite element simulations, optimisations and driving tests under real conditions, we were proud to introduce in 2015 the latest AZ new generation of even more cost-efficient, up to 800mm extra-wide sheet piles!

All our AZ steel sheet piles have the proven Larssen interlock.

AZ sheet piles are usually supplied and driven as double piles (some exceptions apply). Although statically not required, the common interlock can be crimped (standard pattern), thus improving the straightness of the wall and reducing noise when driving with a vibratory hammer.

Not yet convinced about the advantages of the new AZ generation: check the brochures below.
