A trelis fence will not deteriorate or noticeably change colour. Algae, slugs etc. do not readily stick to your fence. It cannot become a home for woodboring insects. It will seldom need cleaning because the rain will wash it clean for you. It will never need painting or creasoteing. All materials used in our fencing range are chosen to last, and are expected to perform their function for a minimum of 10 years, without needing any maintenance.
