Re: Handrails...

[Subject Prev][Subject Next][Thread Prev][Thread Next]
In Canada, for glass guardrails, we are allowed up to 40 mm deflection under specified loads.  I don't like that much since I wouldn't go anywhere near a guard with that much deflection on 42".  I'd say it was a judgement call at that deflection.  I'd go stiffer myself.
"Handrails" are different and don't seem to have a deflection limit applied to them since they are more to guide the hand than be a "guard".

List members:

What is the allowable deflection for a handrail?

I’m reviewing the misc metal guy’s calcs and he’s getting 1.75”

For a 42” high railing on a balcony 10” long (wide).


Seems excessive to me.



Any thoughts?
