In comparison with common steel,fiberglass rebar has a lot of excellent properties,as below

1. Impervious to chloride ion and chemical attack 

2.Tensile strength greater than steel  

3.1/4th weight of steel reinforcement 

4.Transparent to magnetic fields and radio frequencies 

5. Electrically and thermally non-conductive 

The FRP rebar is becoming a promising alternative to steel reinforcement in concrete structures such as marine structures, parking structures, bridge decks, highway under extreme environments, and structures highly susceptible to corrosion and magnetic field
