Constructed from highly durable steel, our Panacea arches have been built to last thanks to the intense three-stage steel-rolling process that they undergo to galvanise them on both the inside and out. This helps to stop them from rotting from the inside whilst also slowing down the natural rusting process. A final layer of protection is added during the powder-coating process which will increase the product's longevity and ensure your furry friends have a life-long safe haven to return to year after year.
