STEEL PIPES & HOLLOW SECTIONS - ITM Global Export

STEEL PIPES

Longitudinally welded pipes of cold-formed base material of round, square and rectangular cross-section are made of hot-rolled or cold-rolled quality tape of structural steels suitable for cold forming, are used for structures in construction and mechanical engineering, agricultural machinery and automotive industry.

Assortment:
Welded pipes for constructions are usually delivered in the qualities of general construction steels S235JR and DD11. Cross-section of steel welded pipes The cross-sectional characteristics are given on the basis of nominal external dimensions and wall thickness.
