The Grouth Steel Group supplies steel products for construction, mining and re-rollers throughout the Middle East and South East Asia.

Growth Steel Round Bars are all 'hot rolled' and produced using both direct rolling from the continuous casting line (for mild steel deformed bar) and by tempering and reheating to rolling temperatures (high tensile grades).

The Growth Steel Round Bars Production is on three dedicated rolling lines and are manufactured under strict quality controls to ensure consistancy and conformity to regional and international standards.

Growth Steel Round Bars are manufactured to, and conform to the major world standards for round bar.

The standards and grades of Growth Steel steel round bars available are:-
