Each intricate laser cut top is made from 14-gauge steel (which is thicker and stronger than 16-gauge). Additionally, each vane has a 3-step coating process for maximum durability against the elements. First, a zinc chrome plating is applied to the base metal for better adhesion, durability, and to help prevent rust. Second, each weathervane is baked in a beautiful powder-coated aged copper finish. Third, a clear powder coat is applied to protect against UV rays and provide a durable, scratch-resistant finish.
