For the ATLAS Phase-II Upgrade the inner tracker of the ATLAS detector will be replaced by the new full silicon tracker ITk designed for operation in the HL-LHC environment. ITk consists of several layers of silicon particle detectors. The innermost layers will be composed of silicon pixel sensors, and the outer layers will consist of silicon microstrip sensors. This contribution focuses on the strip region of the ITk. The central
part of the strip tracker (barrel) will be composed of rectangular short (~2.5 cm) and long (~5 cm) strip sensors. The forward regions of the strip tracker (end-caps) consist of six disks per side, with trapezoidal shaped sensors of various lengths and strip pitches. After the completion of final design reviews in key areas, such as Sensors, Modules, Front-End electronics, and ASICs, a large scale prototyping program has been successfully completed in all areas. In this contribution, we present an overview of the Strip System and highlight the final design choices of sensors, module designs and ASICs. We will summarise results achieved during prototyping and the current status of pre-production and production of various detector components, with an emphasis on QA and QC procedures.
