The material is extruded with a full through colour so if the board is damaged or scratched during landscaping, the area is not clearly visible and will not cause a detrimental effect to the gravel board. Over the lifetime of the product a gradual minor loss of shine may be noticeable, but this will have not detrimental effect to the material. The DuraPost gravel board is extruded from PVCu, manufactured and fully UV stabilised to BS EN ISO 21306-1:2019
