BS 1387 ERW steel tube from TPMC is produced by high-frequency welding of steel strip, featuring a longitudinal weld seam, precise dimensions, and lightweight construction.
Conforming to this established British Standard, our TPMC tube is ideal for welding or threading and suitable for conveying water, gas, air, as well as for general structural applications.
