Abstract: Building Construction Involves Use Of Stirrups To Give Strength To Columns And Beams And Are Widely Used In Various Shapes In Steel Reinforcement. It Is Regular Practice To Make Stirrups On Construction Sites. Existing Engineering Standards Recommend Use Of Continuous Helical Coil For Better Strength Of Structure But It Is Having A Very Rudimentary Level Of Technology. Hence This Work Focuses On Developing A Coiling Machine As An Integrated System Of The Rolling Mill Where The Steel Bars Are Produced. The Integrated Coiling Machine Will Overcome Almost All Problems And Limitations Associated With Manual Stirrup Making And Even Of Semiautomatic And Full Automatic Stirrup Making Machines. This Paper Embarks On Integration Of Stirrup Making Activity With Rolling Mill So As To Take The Advantages Of Plastic Deformation Of Steel At Elevated Temperature, Imbibing The Metallurgical And Mechanical Properties And Eliminating Residual Stresses Compared To Todays Stirrup Making Practices.
