Our stainless steel CNC laser cut Windspinners are available in 3 grades of steel. You can choose 316 marine grade from the Artwerx line which is the least corrosive around salt water. Slightly less expensive 304 stainless steel can be selected on other designs. Our colored models are 201 stainless steel with some models in powder coat paint or anodized coloring. All spinners produce mesmerizing reflections in any light setting.
