I have 6 sheets of melamine coated chipboard in a walnut colour which were used as bi-folding wardrobe doors. Bought from Llandaff Laminates, four are 50cm wide x 9ft 3inches high. and two are 48.5 - 49cm wide and 9ft 3inches high as they were cut down slightly. The two smaller ones are slightly damaged at the top/bottom but would be fine if you didn't need them to be full length. They all have screw holes from where they have been fitted previously.
Would be good for wardrobe doors or other furniture project.
Would need a van to collect as they are very long.
