Standard Q235B Hot Rolled Steel Coil – General Structural Grade
Product Overview
Hot Rolled Steel Coil, commonly abbreviated as HR steel coil or HRC, is the most fundamental steel product manufactured by heating continuous cast slabs to high temperature and rolling them through roughing and finishing mills. Q235B is the most widely used general-purpose carbon structural grade, offering an excellent balance of strength, formability, weldability and cost. It is the workhorse material for construction, machinery manufacturing, pipe production and general industrial fabrication.
