Plastics have come a long way in the past decade. Providing a low impact surface (making them excellent alternative to steel bollards for car-parks and bike paths). Available in large range of colours and even stone look grey or brown. If they scratch they are the same colour all the way though. If the bollard may be subject to impact from vehicles,we recommend the Impact Recovery System which enables the bollard to absorb vehicle impact and be re-used (even if very badly impacted). If you have existing bollards that are looking tired but still on good foundations- a cheap option is to cover them with poly covers- they look great, will not rust or chip and reduce risk of damage to vehicles .
