Why Are Scaffolding Poles Circular?
Why is scaffolding round not square? Everything else - bricks etc - have square edges, why not scaffolding?

James: because circles are stronger - there is no point of pressure.
Kevin: it would be nice to hear it from a structural engineer

Answer: They hold more force when round, even under bridges the pillars are round as they are stronger.
(James: He wanted a structural engineer and you worked it out in school!)
Name: Mark, Croydon
Answer: Round so you can put a scaffold clip on it and pull it tight. It it was square it wouldn't tighten itself around a tube.
James: what came first the poles or the clips? It would be the poles.
