Welded tubes and hollow sections

Electrically welded cold-formed pipes and tubes. They have high torsion resistance, which makes them applicable mainly in the construction of metal and reinforced concrete structures, fences, railings, doors, etc. Circular tubes may additionally undergo hydro-test to ensure their suitability for fluid transfer in installations up to 20 Bar. For the sake of greater corrosion resistance additional hot dip galvanizing is made.
