Wooden backing boards are made on site to suit any size of memorial plaque. They can be made in various timbers. Oak is very beautiful but will need to be oiled to keep it that way. This is also the case for Sapele - a red coloured wood similar to mahogany. Iroko is full of oil so needs less maintenance. As well as different timbers there are different finishes. The black finish looks amazing with a modern stainless steel plaque. Finally you can choose the edge style.
