When can reinforcing steel be field bent?

1. A. after it is heated to cherry red

2. B. when it is cold

3. C. it cannot be field bent

4. D. after it is heated to cherry red, bent, and plunged into cold water

The correct answer is: B. when it is cold

Reinforcing steel can be field bent when it is cold. This practice is acceptable and often necessary for adjustments on-site to fit specific construction requirements. Cold bending typically does not negatively impact the integrity or strength of the rebar, provided that it is done within the specifications set by industry standards. When reinforcing steel is bent in the field, it is crucial to adhere to appropriate bending radii to avoid any structural weakness. This method allows for the necessary adjustments without requiring additional heating or special equipment. On the other hand, bending after heating to cherry red or plunging it into cold water involves practices that may weaken the steel or alter its properties, making those options less suitable or advisable for field situations.
