Product Overview

Our S235JR Hexagonal Bar is low carbon structural hexagonal steel bar produced under EN 10277, base standard EN10025-2. It can be manufactured via hot rolling or cold drawing process. This grade is a popular European structural steel with low carbon content, featuring outstanding weldability, good formability and reliable mechanical properties. Cold drawn S235JR hexagonal bar delivers bright smooth surface and tight dimensional tolerance, while hot rolled variant provides economical bulk supply. S235JR hexagonal bar is widely used for European standard structural components, support brackets, frame fabrication and general mechanical structural parts.
