JIS G3466 Carbon Steel Square and Rectangular Tubes
As a carbon steel pipe supplier and exporter, UNIASEN offers different production procedures for JIS G3466 carbon steel square and rectangular pipes, including resistance welding, forging welding and automatic arc welding. There are two different grades of JIS G 3466 carbon steel square and rectangular pipes: STKR400 and STKR490. The STKR400 grade has excellent weldability and toughness, making it ideal for general structural applications. Conversely, the STKR490 grade offers higher strength for structures that require superior load-bearing capacity.
We offer optional surface coatings for enhanced environmental protection and a variety of end types and joint methods for easy assembly. In addition, we also provide machining services to ensure that your pipes are ready for installation immediately after delivery.
We ensure that you can choose the steel grade that best meets the needs of your project, whether it is a residential building, commercial complex or large-scale infrastructure development.
