You can find it but you need to go imperial
5/8" x 5/8" x 18swg Mild Steel Box which works out at roughly
15.8mm x 15.8mm x 1.21mm
Is that any good for you??? failing that you can get 1/2" square which is about 12.7mm

Because nobody sells it 
You can get 5/8" ERW which is 15.9mm in 18g and 16g from Steelexpress.

My supplier is the same, simply does nothing less than 20mm box unless by special order and then costing 50% more than the 20mm costs.

And in those sizes lies the problem,
We quite often need to modify wheelchair controller brackets, this entails a swing away / cantilever arm arrangement with a 15mm square tube which slides within another tube to give fore / aft adjustment, 15.8 will not fit inside say 16 / 17mm tube for arguments sake, usually because of the ERW seam inside the tube, unfortunately we are governed by the constraints of whatever sizes the chair manufacturers are using for any particular production run, believe me it is a constant daily problem for us and finding the sizes we require from suppliers.
