Welcome to Bulan Pipes and Tubes, your go-to manufacturer and supplier based in Jakarta, Indonesia! We specialize in EN10305-2 / EN10305-3 ERW Tubing, delivering top-notch electric resistance welded (ERW) tubes that are perfect for a variety of mechanical and structural needs. Our products are crafted to meet the EN10305 European standard, ensuring you get exceptional dimensional accuracy, a smooth surface finish, and reliable mechanical properties. These cold-formed welded steel tubes are perfect for everything from automotive applications to furniture, hydraulic systems, and general industrial uses. At Bulan, we’re all about quality control, timely deliveries, and keeping our customers happy, which is why we’re a trusted name for ERW tubing solutions throughout Indonesia and Southeast Asia.
When it comes to EN10305-2 / EN10305-3 ERW Tubing, we use low-carbon steel grades like E155, E195, E235, and E275. The typical chemical makeup includes carbon (≤0.17%), manganese (≤1.20%), along with trace amounts of silicon, phosphorus, and sulfur. Our tubes are cold-formed and welded, then either normalized or stress-relieved to ensure consistent mechanical properties. Depending on the grade, you can expect tensile strengths between 290–580 MPa and yield strengths from 195–275 MPa. These tubes are designed for excellent formability, surface quality, and tight tolerances, making them perfect for precision applications where accuracy and reliability are a must.
