Application： for the manufacture of pipelines, containers, equipment, fittings and mechanical structures .
Types of steel pipe for machine structures
Steel pipe application in structure engineering is generated in the carbon steel smelting defect smelting and casting process, such as segregation, non-metallic inclusions, porosity, shrinkage and cracks.
Steel Pipe for Building Structures
Advanced, high-performance steel pipe that can be found on almost any construction site.
In addition to delivering its highly trusted JIS-compliant steel pipe for building structures (e.g., STK and STKR) for a long time. In addition, we engage constantly and actively in R&D, so that we can deliver even more advanced and capable materials.
Tubes for Tubes for structure
Tubes for structure are used for the manufacture of pipelines, vessels, equipment, pipe fittings, and steel structures.
