The most recent revolution in the steel sheet piling industry started in 2004 with the initial version of the AZ 38 700. It was the first 700 mm wide hot rolled Z-section that instantly made his way into the sheet piling market. 14% of weight reduction, reduced installation time due to its high width, higher stiffness,… to name only a few assets compared to the previous AZ 38. This innovative sheet pile definitely contributed to the execution of more and more cost-efficient sheet piling structures in the higher range of section modulus.
January 2008 was another milestone for this profile. Owing to its success, especially for driving into dense soils, the demand largely exceeded the production capacity of the mill in Belval, Luxembourg. As a consequence of the feedback received from our customers, a new improved shape was launched: the AZ 39-700. A similar geometry, but with an increased web thickness and with a hint of ‘reinforced shoulders’. This minor change of the shape lead to two striking advantages: superior driveability properties, and higher productivity at the mill.
The last chapter of this continuous enhancement will occur in 2011, introducing the AZ 38 700N. A new calibration of the rolling process at the mill allows the manufacturing of this stiffer section, with much thicker ‘reinforced shoulders’, just like the AZ 48. The ultimate edition of this profile is the final stage of the development of this section and will undoubtedly denote a landmark for the future.
The AZ 38-700N will be available for shipment by the second quarter of 2011.
