Steel fixing is the assembly and securing of reinforcing bars, mesh and cages that will sit inside concrete. Steel fixers work from reinforcement drawings and bar schedules, position the steel with the specified supports and prepare it for the project's inspection process. They do not replace the structural designer.
What the work involves
The task can include sorting reinforcement, placing bars and mesh, tying intersections, assembling cages and coordinating starters, laps, spacers and openings. The exact method depends on the structure and issued project information.
What needs to be ready
Current drawings, bar schedules, reinforcement deliveries, lifting arrangements, safe access and a clear workfront are basic inputs. Congested areas and revised details need early review so the team is not solving design questions at the fixing face.
Where responsibility changes
Fixers install to the information provided. Design changes, alternative bar arrangements and approval of reinforcement sit with the responsible project professionals and quality process.

Questions people ask
Is steel fixing the same as rebar installation?
In UK site language the terms commonly describe the same reinforcement installation activity.
Does a steel fixer design the reinforcement?
No. Reinforcement design and approval belong to the responsible engineering process.
General UK construction information only. Project drawings, specifications, appointments, contracts, competent advice and site controls take precedence.
