EN 10305-1 / EN 10305-4 Seamless Tubing is expertly crafted steel tubing designed for high-performance applications that demand exceptional dimensional accuracy and cleanliness on the inside. Shalan Steel, located in Kuala Lumpur, Malaysia, stands out as a top supplier and manufacturer of premium seamless tubes that adhere to European standards for automotive, hydraulic, mechanical, and structural uses. The EN 10305-1 tubes are cold drawn and primarily utilized in general mechanical engineering, while the EN 10305-4 tubes are tailored specifically for hydraulic and pneumatic pressure systems. Shalan Steel is committed to providing a reliable supply, competitive pricing, and technical know-how to support customers throughout Malaysia and Southeast Asia.
The EN 10305-1 seamless tubes are made from non-alloy steel and are cold drawn to achieve tight dimensional tolerances, smooth surfaces, and high precision. Similarly, the EN 10305-4 tubes are also cold drawn but are produced with stricter internal cleanliness standards, making them ideal for pressure lines. Both types typically boast yield strengths ranging from 235 to 580 MPa and tensile strengths from 340 to 700 MPa, depending on the steel grade (like E235 or E355). These tubes are known for their excellent formability, weldability, and internal surface finish. They come in various delivery conditions, such as cold drawn/hard, soft, or stress-relieved, providing flexibility for further processing.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
EN 10305-1 / EN 10305-4 Seamless Tubing finds its place in applications where high precision, surface quality, and mechanical reliability are crucial. EN 10305-1 tubes are commonly used in mechanical components, drive shafts, rollers, and automotive parts. On the other hand, EN 10305-4 is particularly well-suited for hydraulic and pneumatic systems, brake lines, and fluid power applications due to its clean internal surfaces and ability to withstand pressure. These tubes are also utilized in industrial automation, robotics, and machinery construction.
