STEEL BILLET AQS B500WR
AQS Steel Billet is a carbon steel semi-finished product designed for rolling high-adherence round steel concrete products. The official AQS product page describes billet as a metal section used to roll into bars and profiles, produced either from ingots or directly by continuous casting, and used as raw material for extrusion, forging, rolling, and other metal processing operations. The AQS technical sheet identifies the grade as B500WR and specifies a 150 × 150 mm section, with strict geometric, surface, and macrographic requirements.
