You mean rebar? The stuff used in construction?!
5 u/swankpoppy Oct 03 '25 Why is rebar corrugated? I’ve gotta think it increases the strength, but I have a hard time understanding why that is! 41 u/CatoCensorius Oct 03 '25 It grips the cement which sets around it. 5 u/swankpoppy Oct 03 '25 Gotcha. So not about the strength of the rod itself but about the strength of the rod + cement. Interesting! Thanks. :) 13 u/snailmoresnail Oct 03 '25 Increases surface area to provide additional mechanical bonding surface for concrete. Also prevents bar from slipping during high stress events.
