From here you can get single plates. You do not need to add one, because all HMKB kits already include a plate. Adding an extra plate here, makes sense if you like to have a spare one or if you want to build a second pcb-plate-switch-stack, for swapping.
Here are standard steel and brass plates. Both go through a galvanizing process which adds a black zinc layer. This protects the steel plate from corrosion and the brass plate from tarnishing. Furthermore, the brass plate gets bead blasted before the zinc treatment.
Both steel and brass plate have a bridge cut around the mounting points. This cut is meant to provide a slight, overall give to the plate assembly.
TPU Grommets are used to fully isolate the plate from the enclosure.
These plates are ANSI/ISO unified, except for the two orthogonal variants 40% and Boardwalk. All support PCB-mounted stabilizers. Furthermore, all plates are open sourced and downloadable from the HMKB discord server. Even more uncommon layouts are available there.
See all possible layout options on the dedicated layouts page.
Depending on the combination of your plate and PCB, many different layouts can be build. To see exactly which layouts you can build with your desired HMKB size and version, please go to the layouts page to learn more.

For powder coating the parts are put on racks. This will leave a little mark. It is usually at one of the holes. Since the holes will be covered by the bolt heads, these marks will not be visible when the case is assembled. Although highly unlikely, it is possible that dust particles may be caught in the powder coating.
The bending process leaves slight marks. They are not a concern for the powder coated steel parts and not be visible at all. The stainless steel parts are not powder coated but bead blasted instead. On all of the prototypes the bead blasting removed those marks completely and they were not present anymore. Still, there is a small chance that some stainless steel parts may show slight traces of these marks, even after the bead blasting.
The angles of the flanges may not always be perfectly 90˚. Though unlikely, a deviation of up to 1˚ can occur. This would still be hardly noticeable.
The switch plates can have scratches.
None of these effects are considered a defect.
