There are an enormous amount of decorative elements used on wrought iron fencing, and one of the most common are called scrolls. These are a form of spire decoration and their construction is based on the top of a spire curling around itself. Other aesthetic elements include things like S and C scrolls (scrolls that form the shape of these letters), twists that can be customised to virtually any shape or form, decorative insets, symbols and symmetrical elements. Other popular wrought iron fence elements include spirals, swirls, spears, vines, intricate curves, arches, twisted columns, gothic shapes, baroque-inspired designs and circle and sphere accents.
