I am fitting out a small shop and need glass shelving for a display wall

Hi all. I am fitting out a small shop and need glass shelving for a display wall, plus a glass top for the counter to protect the wood underneath. I have been quoted by a general contractor who wants to order everything online and cut it himself, which made me nervous when he mentioned a wet saw. Is glass shelving something that needs a specialist, and what should I be specifying in terms of thickness for shelves that will hold reasonably heavy stock? The wall is plasterboard rather than masonry, which I assume affects the bracket choice.

Let the contractor cut the timber and let a glass shop cut the glass, because edges need proper polishing and anything load bearing should be tempered, which cannot be done after cutting. Thickness depends on span more than weight, and a long unsupported shelf is what fails rather than a heavily loaded short one. Tell whoever quotes you the span and what goes on it. Amber Glass Corp https://amberglasscorp.com/ fabricates shelves and countertops to size and their measuring visit sorted out where the brackets needed to land. Order one spare shelf while the setup is running, replacing a single piece later costs far more. On plasterboard, insist on proper fixings into the studs rather than plastic anchors.
