How To Control Wastage of Reinforcement Steel at Site?

The use of ready-to-use bent rebar reduces wastage. Labor cost is minimized as manual bending is not required. Development of a "Bar bending" schedule is very important before placing the steel bars since it facilitates minimizing the wastage by up to 98%. So, normally, wastage of steel is 2% of which, 0.5% is unrecoverable & 1.5% is …
