We serve a multitude markets and industries worldwide with our products
Founded in 1923 by Irving M. Hayward, Hayward Industries was a small company located in Brooklyn, NY, making specialty metal valves and industrial flow control products. When Mr. Hayward retired in 1964, our present management acquired the company and has remained family owned. With that, a new period of growth and diversification began, one that continues to this day. Management realized an opportunity existed for thermoplastic, rather than metal, swimming pool filters and accessories, and diversified into the swimming pool market. Rapid growth in the pool business resulted in the creation of Hayward Pool Products, Inc. At the same time, through a combination of acquisitions, modernization of the manufacturing facilities and product innovations, the industrial thermoplastic valve and strainer business grew as well—and became Hayward Flow Control.
