We make menu signs a few different ways depending on budget and requirement. Probably the most common would be a printed men vinyl applied to a 10mm foam pvc sheet.
A more convenient product which we use more now, is the magnetised menu. We supply the magnetic base which screw fixes to the wall, then make a printed magnetic menu sheet to fix straight to the base. This allows for new printed menu sheets or updated menu info to be produced time and time again without changing the base, which makes changing your menu signage much cheaper in the long run.
We also make menu slips for illuminated signs with plastic runners.
