It is actually Charge-productive as reduced labor requirements are there. It offers automated positioning reinforcement which minimizes job Expense.
Rebar's area is patterned to kind an even better bond Together with the concrete. When additional to concrete, the rebar provides strength and flexibility, which concrete by yourself does not have.
