Steel tubes

Welded round steel pipes are proven and used in various applications but especially for water pipes.

Black steel clamp tubes are round hollow steel profiles determined by a diameter or by an external section and a thickness. They are therefore provided with a weld on the inside.

They are cold-formed and electrically welded out of black hot-rolled strip, then hot-dip galvanized. The cold forming of round steel tubes allows to obtain a smooth surface which guarantees a considerable advantage when painting or applying any other protection.
