Arvedi Tubi Acciaio is the European leader in the production of hot rolled tubes for the manufacture of self-drilling anchor systems, used for tunnelling, mining consolidation, for steep slopes and landslides stabilising. The standard steel grades are S355J2H, S355NH, S355 mod, S460NH, 28MN6, 34MNB5, 38MNB5. In collaboration with its customers’ technical offices ATA studies and develops suitably customised and optimised steel grades and specific sizes in order to increase the workability of the anchors and obtain the best performances on site and in operation. Micropiling is produced in compliance with standard EN 10219 or EN 10296 in commercial length bars, with the internal bead removed and with smooth ends in the following steel grades: For the steel grades included in the standard EN10210-1 and EN10219-1 supplies are CE certified and are accompanied by EN10204 certificate and declaration of performance (in accordance with Regulation EU 305/2011). These special profiles are produced according to customer requirements or according to ATA specification and can be supplied as weld based on tailored chemical analysis or full body normalized.
