Wrought iron railing is metalwork made from iron that has been heated and shaped by hand or machine. It is valued in luxury homes for its strength, durability and ability to be formed into intricate designs that complement historic architectural styles. Unlike hollow aluminum alternatives, solid wrought iron has visible heft and texture. In the Santa Barbara Estate, the upstairs balcony uses solid wrought iron pickets throughout, contributing to the home’s Spanish Colonial character and adding substantial weight that reinforces the self-supporting structure.
