RE: Glass guardrail support

We have a rule-of-thumb span/175 for glazing systems eg storefront etc.  For railings we have a monstrous 42mm (1.5").

 

I wouldn't go near any railing that deflected that much ...

Do hand rails, glass or otherwise, have deflection requirements? I have never found it, but I prefer something very solid.

Back in years gone by we simply required the guard rails to be tested after they were installed.  I was amazed how much glass could bend, but they performed well, and I slept well.
