Structural Spiral Strands
This kind of “rope” it is specifically dedicated to static applications such as: structural constructions, bridges and everywhere it is needed to get lighter load bearing components respect to the standard materials (concrete, steel bars, lamellar wood, etc.) and at the same time related to aesthetic concerns.
SIRTEF has developed several projects with spiral strands and special end terminations such as bridges, footpaths, frontispiece of fascinating buildings, panorama mountain structures, motorway toll houses, etc.

Further to the engineering, manufacturing and installation of pennants and related steel components, we are able to test all the products thanks to specific devices and skilled and qualified personnel. We can perform NDT (MPI, UT, PT) if it is the case witnessed by Third Parties qualified I.A.C.S.(Lloyd’s Register, R.I.Na., D.N.V., B.V. , A.B.S., etc.).

We have a pre-stretching line in house that allows us to perform proof load tests and to tension the strands during the measuring and cutting activities.
