A steel fixer is a skilled tradesperson who positions and secures steel reinforcement bars (rebar) and mesh within concrete forms to create strong, stable, and durable structures like buildings, bridges, and other large infrastructure projects. Key responsibilities include interpreting blueprints, cutting and bending steel to specific shapes, tying the rebar together with wire, clips, or welds, and ensuring precise placement according to engineering plans. Steel fixers work as part of a construction team, collaborating with engineers and other tradespeople to ensure structural integrity.
