I'm looking to build some shelves in my garage to store 100L totes, specifically above my workbench since that space is going unused. I'm inspired by a shelf design I found and want to optimize it by rotating the totes for more efficient storage. How much weight can I expect my shelves to hold? Any advice on materials and construction methods?

The weight capacity really depends on how you build them. If you follow a solid construction method, you can expect those shelves to hold several hundred pounds evenly distributed. Just make sure you securely anchor them to the wall by hitting the studs behind the drywall.
When I built my shelves, I made them 2 feet deep and high, using 3/4 inch plywood. I reinforce the outer edges with 2x2 or 2x4. Instead of brackets, I support the free end with chains bolted into the ceiling rafters. Just ensure you use strong, welded link chains and that your lag bolts go deep into the rafters for stability.
If your shelves are constructed properly, each shelf can hold a few hundred pounds without issue. The biggest tip is to ensure your fasteners are securely anchored into the wall studs and use washers to keep the heads of the fasteners from pulling through the wood.
Would using construction screws, with four of them per board, be enough for support, or do I need to go with something heavier?
Be careful with that method! It's better to screw a 2x4 across the trusses to spread the load rather than putting lag screws directly into the trusses. Look for screws from brands like GRK or Spax; they’re easier to work with and have great holding power.
