Our products are of superior quality and they undergo all the required testing. Great Steel & Metals manufactures different Duplex Stainless Steel Rod and other products in different duplex grades. There are standard duplex, super duplex and lean duplex grade bars and the ASME SA276 Super Duplex Hex Bar is a standard duplex bar that is produced for strength. The hex bars are usually used in applications that require more structural strength. The hex bars provide the structural strength because of their shapes. Since the SA276 is a standard duplex, it is also very cost effective.


What is Duplex Round Bar?

We also produce super duplex and lean duplex bars. The Super Duplex Threaded Rod is used in applications where the rods have to be attached with bolts, nuts, screws or with threads. The super duplex offers high corrosion resistance advantages to the bars and rods. Our Super Duplex Flat Bar is used in decorative applications and in structural applications. The super duplex material provides a combination of strength, corrosion resistance and an appealing look as well. You can contact us for our duplex bar list and pricing.
