Each wrought iron fence has a unique custom design. Notable features can include decorative collars and bases that cover the welding marks that connect different shaped balusters and posts. Within each section of fence or gate door you may have features such as rosettes, panels, plaques or corner castings. Balusters may be adorned with a decorative fleur-de-lis, spear, finial or cap. The more detail a fence has, the more likely moisture will puddle up and start to rust the wrought iron fence over time. Paint your wrought iron fence with a rust inhibitive paint to protect against corrosion.
