Investigating the standard sizes of steel reinforcement used in the Ghanaian industry

The study aimed to explore and determine whether the steel reinforcement bars manufactured and used in Ghana meet the standard sizes. The research adopted a positivist philosophy and a market survey approach. The various organizations manufacturing and supplying steel reinforcement were purposively selected and visited, and the different steel reinforcement bars were measured against the standard sizes. When the measured sizes were compared to the standard sizes, the results revealed that all the mild steel reinforcement bars measured did not meet the required standard sizes. The results showed that all the high tensile steel reinforcement bars met the necessary standard sizes in the Ghanaian construction market. The research empirically demonstrated that non-standard steel reinforcement bar sizes impact most project outcomes. The regulatory authority (National Standard Authority) must ensure that both manufactured and imported steel reinforcement bars meet the standard sizes on the construction market in Ghana to keep the project under control and enable the structure to achieve its maximum strength.
