This rebar is harder than the previous ones and is produced in a ribbed form with a spindle-shaped compound tread. However, this type of rebar is less used in the construction of structures than the aforementioned rebars, and over time we should see more use of this type of rebar.
Advantages of using A4 rebars:
-Reducing the volume of rebars in dense concrete members
-Reducing the cross-sectional area and amount of rebars used in concrete
– Convenient and appropriate placement of concrete between the rebars
– Increasing the resistance and durability of structural members against corrosion
– Reducing environmental damage due to optimal use of materials
– Saving in implementation costs
– Increasing the speed of reinforcement and concreting, and consequently increasing the speed of construction of the structure
