Diamond Plastics Corporation is the producer of the world`s largest PVC pipe through seven strategically located plants throughout the USA.

We started with a strong belief that PVC pipe was the best value in the piping industry. We added to that the personal challenge to become and remain the most efficient producer of that product. We finish by supporting the product with customer service and technical assistance. The result is a quality product at a good price that serves the customer with excellence. It sounds simple, but we insist that every decision we make is measured against that standard.

Today, Diamond offers the industry`s broadest range of PVC pipe sizes, with diameters from 2 inches to 60 inches. No other company makes a higher quality, longer lasting PVC pipe than Diamond Plastics. Even though Diamond has grown to serve more customers with a larger volume of pipe and piping products over the years, we have not relaxed our views on the importance of a dedicated staff, exceptional service and unparalleled quality, which you can further learn about below.
