We are a commercial printer in Yorkshire and wish to replace MDF 'end boards' that are used as part of our internal handling process with plastic 'end boards' that will have a long life. Can you recommend any supppliers who could work with us to design and supply a suitable product. We will need at least 2 different sizes and approximately 40,000 of each one. The design to give the appropriate strength is likely to be key for one size in particular
