About DuraMAX Building Products

DuraMax is a division of US Polymers Inc., a leading California extruder of vinyl products, including fencing, sheds, pipes, shutters and custom profiles, since 1983.  

US Polymers is part of the international Harwal Group of companies, with units in the US, Middle East, Europe and former Soviet Union. Harwal Group has more than 65 years experience in manufacturing plastic and metal products throughout the world. With an annual conversion capacity of over 200,000 metric tons of plastic and 20,000 tons of aluminum, Harwal Group’s size and financial clout confer competitive advantages in the industries served by each unit, including US polymers.

In the case of the DuraMax division of US Polymers, our competitive advantage includes the resources to exploit our unique location in Southern California, where vinyl fencing and other building products are enjoying the most rapid growth. Since all the other US extruders are located in the East and Midwest, competitors must ship their products great distances in order to serve the market in the Southwest. Their fence dealers and fabricators face shipping and inventory problems and therefore higher operating costs. DuraMax exploits and compounds this competitive advantage by offering free shipping and making free deliveries throughout the western US.

Innovation. DuraMax has developed a proprietary resin formulation that better withstands the more intense sun in the Southwest. A smaller company with fewer resources might not have been able to translate these potential advantages into growing sales and an expanding network of profitable dealers and fabricators.

DuraMax is committed to delivering quality products with a level of service that ensures that its network of customers are able to satisfy the needs of today’s consumers. 

Through this commitment, we develop close relationships with our dealer network, stay on the leading edge of consumer demands and deliver unparalleled satisfaction to consumers.
