What is the maximum number of parallel bars that can be bundled together and still be considered a single unit?

• A. 3 bars
• B. 4 bars
• C. 5 bars
• D. 6 bars

Answer: (B)

Bundling parallel reinforcing bars is treated as a single unit only up to a practical limit. This limit exists because tying and handling a bundle must stay stable and manageable; once you exceed that limit, the group becomes difficult to tie securely, may slip or spread, and is no longer reliably moved or counted as one unit. So, there’s a standard maximum size that can still be treated as one unit for estimating and handling. The correct choice is the option that represents this typical maximum practical bundle size.
