Growth Steel Angle Bars are all 'hot rolled' and produced using both direct rolling from the continuous casting line and by reheating to rolling temperatures. The Growth Steel Angle Bars Production is on three dedicated rolling lines and the angle bars are manufactured under strict quality controls to ensure consistancy and conformity to regional and international standards. Growth Steel Angle Bars are manufactured to, and conform to the major world standards for angle bar. The standards and grades of Growth Steel steel angle bars available are:- JIS G3101: 2004, Grade SS400 Yield Point – 245 N/mm2 min.
