Carbon Steel Welded Tubes
More than 60 years of history has led Marcegaglia to develop the world’s widest range of carbon steel welded tubes in terms of steel grades and dimensions, compliant with the requirements of several industry sectors.
Marcegaglia ERW carbon steel tubing manufacturing is at the core of the group activities since its foundation, and now counts on 150 tube mills worldwide and an overall manufacturing capacity of more than 3 million tons/year. The fabrication process is compliant with all main European norms.
Marcegaglia UK is the largest precision tube manufacturer in Great Britain, with a total output capacity of more than 100,000 tonnes of finished products.
Marcegaglia UK production of carbon steel welded tubes is ISO 9001 certified by SGS since 12/01/1996 and is in according to EN 10305-3, EN 10305-5 and EN 10219 manufacturing standards.
