Types of steel bars used in construction- Characteristic

Mild steel bars are ductile,they are not preferred over high yield strength deformed bars because it has less strength and weak bond.The modulus of elasticity of mild steel is taken as equal to 2 x 10 5 N/mm 2.In columns,they are used as lateral ties and at places where nominal reinforcement is required.Mild steel plain bars are denoted by What is Rebar? Types and Grades of Steel ReinforcementHigh strength deformed bars are cold twisted steel bars with lugs,ribs,projection or deformation on the surface.It the extensively and majorly used for reinforcement purposes in a construction.These bars are produced in sizes or sections from 4 mm to 50 mm in diameter.Fig 4 Deformed HSD Steel Bar.What is a TMT steel rod ? What is the difference between Sep 09,2019·HYSD is short for High Yielding Strength Deformed bars.The processes applied to TMT and HYSD bars differ resulting in different properties and quality in these two types of bars.
