Micheal,
A question came back from our handrail fabricator about the material for the rails. I have attached a copy of question below.
Is ASTM A500 acceptable in place of ASTM 53? This question came up for the City of Kent also and the EOR didn’t have an issue nor did the City of Kent but I wanted to ask you about this.
Thanks,
Craig
