EN 10255 ERW steel tube from TPMC is produced by high-frequency welding of steel strip, featuring a longitudinal weld seam, precise dimensions, and lightweight construction.
FM Approved, it provides reliable performance in water-based fire protection systems, including wet, dry, deluge, and preaction pipelines.
Additionally, our TPMC tube is ideal for welding or threading and suitable for conveying water, gas, air, as well as for general structural applications.
