A steel fixer's job involves interpreting construction plans to install and secure steel reinforcement (rebar) in concrete structures, ensuring structural integrity and stability. Key responsibilities include cutting, bending, and shaping steel, assembling it into cages or grids, and fixing it into position with wire, clips, or welding. This role requires physical fitness, the ability to use hand and power tools, and adherence to safety protocols, as steel fixers work outdoors in various conditions and play a vital part in construction projects.
