Types of reinforcement

Types of reinforcement

1. Mild steel reinforcement

• these bars have carbon content high ductility & less strength 

Eg.Fe-250

• IS 432 is used for consideration of mild steel bars.

2. HYSD bars – High yield strength deformed Bars)

• these bars contain high yield strength & low ductility 

E.g. – Fe-415 & Fe-500

• These bars may be in the form of cold twisted deformed bars (CTD)

3. TMT Bars – (thermo mechanically treated bars)

• these bard are thermally & mechanically treated.

• IS 1783 includes the introduction of TMT bars & HYSD Bars

e.g. Fe-550, Fe-600 & so on.
