Liz, I'm not sure I understand the reason for your last four references and was wondering if you could maybe explain why you have them (I don't want to agree/disagree with your answer in case I've missed something). They are all related to steel reinforcement bars that would be used in concrete stairs. Are you saying that although this this term is normally used in the context of concrete stairs, it has been 'borrowed' to describe this bar in the scaffolding tower staircase? Also, is the starter bar not horizontal (I would have thought that a post would be vertical)? |
