All of our items are made from galvanised Steel, which is then hot dipped into molten Zinc. Our products are then treated and finished to look like Lead.
Over time this finish will lighten and age down to a patina finish. White markings and colour differences are all normal characteristics of our products.
For all Zinc items we offer a 5 year warranty. However, the use of caustic chemicals to treat / clean the products will make your warranty invalid.
