Build plywood box yourself

[Hobbit]

Hello,
I am going to start building my own plywood boxes for my larger and more expensive tools that usually come in a systainer.
All the plywood boxes on the market are either too small or have the wrong dimensions so it's time to craft my own.

The result should look like this

Just wondering what the edge reinforcement and protective support in sheet metal are called and where to buy them.

Preferably with holes and not so dizzyingly expensive ....

Hello

I've also considered building such things but got four Nefab boxes, so the need was satisfied.

I would have used plasterboard corner beads as reinforcements, which I would have fixed with rivets or something. Cheap.
Best regards, P
