ArcelorMittal is striving to match its offer to the requirements of its professional partners, and the latest proof of this success is the high demand for the AZ 38-700 sheet pile section. This section is being used increasingly in quite large structures, like quay walls with deep dredge levels, and in very dense soils. These projects were in the past mostly executed with stronger sheet piles, like the AZ 48 section. Taking into consideration the feedback from several driving contractors and project owners, our R&D improved the existing shape. It will meet the requirements for large sheet pile sections, which can be hot rolled up to 31 m, in high steel grades, and will allow our customers to drive this new shape in longer lengths into more compact soils.
A first step into this direction is to optimize the geometry of the section to stiffen the transition flange / web of the sheet pile, keeping the same thickness of the flange and the width of the sheet pile. Close to the flange, the thickness of the web is increased. The result will yield a new section, the AZ 39-700, with ‘reinforced shoulders’ similar to the AZ 48, which replaces the existing AZ 38-700. This new AZ 39-700 will be available in January 2008, and provides a higher section modulus Wx, and a stiffer driving element.
ArcelorMittal will monitor the feedback of the new AZ 39-700 and if required, continue adapting this highly competitive sheet pile section to the requirements of our customers.
