This study investigates the diameter characteristics of reinforcement steel bars commonly used in construction. Measurements were taken for both 10mm and 12mm diameter bars obtained from distributors, revealing mean diameters of 9.66mm and 11.46mm, respectively—both falling below industry-standard dimensions. Statistical analysis, with standard deviations of 0.47 and 0.40 for 10mm and 12mm bars, respectively, indicates consistent measurements around the means. While this uniformity is a positive aspect for quality control, the deviation from standard sizes raises concerns about the structural implications and adherence to industry specifications. The undersized bars may compromise load-bearing capacity, necessitating further investigation into manufacturing processes and the implementation of robust quality assurance measures in the construction industry. The findings underscore the critical importance of ensuring construction materials meet established standards for the safety and reliability of built structures.
