When reinforcing bars are used around curved surfaces and no special requirements are established, how are they prefabricated?

• A. Radial prefabrication table
• B. Standard straight bars
• C. Bent into coils
• D. Prefabricated in place

Answer: (A)

When bars need to follow a curved surface, precise shaping is essential to fit the curve and maintain proper spacing and cover. A radial prefabrication table provides a way to bend bars into a curved pattern with a common center, so each bar conforms to the curve exactly as it’s placed around the surface. This off-site preparation makes the curved reinforcement predictable and consistent, reduces labor and field mistakes, and minimizes damage to the steel that can happen with on-site bending. Using standard straight bars wouldn’t match the curve, and bending in place on the job can lead to irregularities or over-bending. Bending into coils doesn’t create the required curve around a surface, and prefabricating in place bypasses the efficiency and accuracy of pre-bent pieces.
