Four container styles sit on this page: collapsible containers that fold down, heavy duty rigid containers, corrugated containers built for bulk parts storage, and parts containers meant to sit at a work station. All of them are for holding loose parts in volume rather than for shelving finished goods.
Collapsible units fold down when they are empty, which matters when containers cycle back empty and you are storing or shipping that empty volume. Rigid units stay assembled and are the simpler answer when the same containers stay in service in one building and nobody wants a fold-down mechanism to look after.
The right pick comes down to what the parts weigh, how much floor you can give up per container, and how the containers get moved and refilled. Tell us those three and we will narrow the list for you.
