The above statement is absolutely NOT true. Many tank manufacturers make 55's with untempered glass.
Ocean View Aquariums - not tempered
GlassCages - not tempered
P.S. - I disagree with using silicon on bulkheads. If installed correctly, silicon should never need to be used. I have installed hundreds of bulkheads in tanks (both my own, and customers' tanks) and never used silicon. In over 12 years, I have never had a bulkhead leak. Even some manufacturer's directions say not to overtighten, and not to use silicon.
