Promostar is the leader company and the first one to introduce the stretching process, the technology that was developed in the 90’s as a new process for the production of anti-seismic reinforcing products.

The process is used nowadays all over the world to produce the high ductility reinforcing materials in different formats, such as compact coils, bars, electrowelded meshes, lattice girders, stirrup, cages, etc. transforming the characteristics of the ribbed wire rod/rebar in coils through a cold process. The final product obtained by stretching process in the form of compact coils presents uniform characteristics and lower industrial costs compared to the hot rolled ones.
