..just don't install the wheels.
Both issues are easily improved. Either add c-channel or a sheet of plywood under the bottom, use BETTER wheels.
Add thin, rigid liners to each drawer to better carry the loads to the edges.
None of the "technology" in a tool/parts storage cabinet is at all mysterious.
We just tend to KEEP the buggers 20 or 50 years, so "mostly" have lost MORE money buying cheaper and suffering off the shortcomings than buying better and suffering less.
Near EVERYONE HERE is craft-capable enough to beat the quality of any brand so far mentioned off nothing more complicated than the lend or hire of a decent box brake and a choice to use heavier-gage metal to begin with.
Ball-bearing slides, wheels, latches are all commodity items, "frames" even easier to fab than drawers. Drill, then rivet or bolt, weld if you can do, and soon DONE.
We simply, "on average", have other s**t to DO
with higher-priorities or more money at stake.
So we use a sub-optimal compromise.... and kick the can down the road.
Yet-again. BFD. It ain't a hotel nor GI mess-hall walk-in food-freezer nor a bio-Warfare storage vault. It only has to work better than NUTHIN atall and we make the spend.
