Our weather vanes are made in the USA. We use 14 gauge steel and they come with a one year warranty on the finish and a lifetime warranty on all workmanship. We use a 3 step finishing process- First we zinc plate our units for better adhesion and durability, then we bake on an antique copper vein powder coat followed by a clear powder coat to protect against the UV rays. This provides a durable, scratch resistant finish. We use sealed ball bearings in our wind cups to keep them spinning freely with even the slightest breeze. Our design tops are laser cut in one piece, minimizing welding and making them a unique addition to your home.
