Ancrages portuaires

La GTM France produce since 2002 also custom made Post-Tensioning Systems and  Post-Tensioning bars & passive anchors (tie rods) and Hangers (Tension Structures).

The tie rods / passive anchors for port extensions can be placed between sheet piles or concrete walls.

We have our own heat treatment furnaces, straightening-, peeling-, thread rolling and other machines so we are able to deliver “custom made” according to the individual requirements.

We have our own heat treatment furnaces, straightening-, peeling-, thread rolling and other machines so we are able to deliver “custom made” according to the individual requirements.

To optimize the resistant section of our tie rods / passive anchors, we can supply upset end tie rods (screwed or spherical eyes) in length up to 18 meters depending on the site specifications.

All the tie rods including plates, nuts and sleeves can be supplied with or without spherical bearing to accept any inclinations.

Each plate is sized according to the surface specifications, concrete, walling systems or sheet piles.
Our walling systems in grade S235, S275, S355 or S460 are manufactured in length up to 15 meters and delivered with the fixing accessories.

Our product range for port buildings are rods in grade S355, S460, E 500 , E700 and accessories such as:

  • Usual tie rods (M20 to M170) in length up to 18 meters max.
  • Upset tie rods ends until M150, (picture “DSC_2386 Upset end tie”)
  • Eye tie rods (picture: eye tie rods)

  • Short or long sleeves for adjustment, coupling sleeves (picture “sleeves”)
  • Walling systems in UPN, UPE and HEA, … (picture liernes)
  • Fasteners on concrete or metal walls
