Re: Glass Railing

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The manufacturer of the glass *should* be able to provide properties.  

I got involved in vertical sections of tempered glass (display windows)
inside a shopping mall some years ago.  I was amazed at how *strong*
tempered glass could be.

A cautionary note...  I had to call-for a thicker section than originally
proposed -- for deflection, not strength.  We recognized that someone
pushing on one section of glass could deflect the panel far enough to leave
a finger-width gap at the adjacent panel -- 'Just the thing for amputating
small fingers.  

Your span is relatively small and, offhand, the thickness seems okay.  When
you crunch the numbers tho', you don't want to overlook deflection(s).
