EN 10305-2 / EN 10305-3 ERW Tubing is a type of steel tubing that’s precision-engineered through electric resistance welding (ERW), making it a go-to choice for automotive, mechanical, and structural applications. Shalan Steel, a top-notch supplier and manufacturer based in Kuala Lumpur, Malaysia, provides high-quality ERW tubes that adhere to EN standards for dimensional accuracy, surface quality, and consistent mechanical performance. These tubes are crafted from either cold-rolled or hot-rolled steel, perfect for situations where tight tolerances, smooth finishes, and dependable strength are essential. With reliable delivery, expert technical support, and competitive pricing, Shalan Steel caters to a diverse range of industries across Malaysia and Southeast Asia.
The EN 10305-2 ERW Tubes are made from non-alloy steel and come in either normalized or cold-finished conditions, while the EN 10305-3 ERW Tubes are welded from precision cold-drawn strips. These tubes boast tight dimensional tolerances and an excellent surface finish. The mechanical properties can vary based on the steel grade, typically featuring yield strengths ranging from 235 to 420 MPa and tensile strengths from 340 to 650 MPa. They are known for their good machinability, weldability, and formability. EN 10305 tubes are distinguished by their high concentricity, smooth surfaces, and uniform wall thickness, making them ideal for further processing like bending, flaring, and machining.
