Construction Pipes And Piles

Lengths of up to 36 meters and heavy wall thicknesses make stable and long lasting constructions possible.

Construction Pipes as an important component

… of the construction supply industry are finding a steadily increasing market, especially for steel light weight construction.

  • Lengths of up to 36 meters and heavy wall thicknesses make stable and long lasting constructions possible.
  • Steel pipe is specially suited for light weight construction due to its equal bending resistance to all sides and due to its low weight (up to 50% reduction).
  • Since the material is inherently flexible, steel pipes are excellently useful for building even difficult symmetries

Requirement Profile

… for construction pipes and piles (hollow sections):

  • Use of high quality steel grades such as X 70, S275, or S355
  • Demanding requirements for statics and buckling load according to DIN 18800
  • In case of damage, the material only bursts in small sections (from one seam to the next)
  • High quality anti-corrosion on the inside and outside
  • The producer guarantees for the constant quality of the pipes throughout the whole project
  • The supplier furnishes JIT logistics right up to the construction site
  • High assembling performance through continuous coordination between manufacturing and processing party
  • Long lifetime of the hollow sections

Manufacturing

… construction pipes and piles needs the experience of many years.

  • Use of high-strength, elastic, and tough steel grades
  • Helical decoiling using a decoiling equipment and subsequent forming via a straightening equipment
  • Joining (on the interior and exterior) using the submerged-arc welding process (SAW)
  • Pipe lengths of up to 36 m are possible
  • The pipes are “round by nature” throughout their whole length (without re-calibration)
  • Comprehensive tests are run throughout the whole production
  • Each single processing step is meticulously documented.
  • Closest tolerances are achieved concerning straightness, ovality and exactness of the diameter.
