Bar accessories
Stahlwerk Annahütte manufactures in its Hammerau facilities a complete range of complementary accessories for the multiple applications of its bars. Among them we can highlight: splice sleeves, nuts and locknuts, plates, anchor end pieces, cones, expansion studs etc.
The system of thread makes possible the cut and union by means of sleeves of the bars in any point. The different systems of connection SAS allow the coupling of bars when they work, to traction, compression, when they are subjected to alternative loads or in post-stressing jobs.
SAS Systems allow the union of two bars in different situations:
- When both can be moved longitudinally and rotated
- When one of the bars can be moved longitudinally but not rotated
- When one of the bars can not be moved longitudinally or rotated
Since its creation in 1970, the UNETRA SYSTEMS Company has been engaged in the manufacture and commercialization of formwork accessories.
The activity began with the manufacture of the eccentric tensioner, better known as the UNETRA tensioner. Subsequently, and in line with the evolution of shuttering technology, we have incorporated new techniques and products into our catalog.
Currently, the range of products sold, in addition to the UNETRA tensioner, always very useful in the works, includes all the necessary accessories to the use of self-reinforcing panels of large dimensions such as the threaded bar SAS, nuts of various models, etc. The activity of SAS UNETRA also extends to the field of scaffolding accessories. We cover an important part of the market in this way, which also allows us to offer an ever more complete service to the contractors of the sector.
The items we sell are subject to a rigorous quality control, which allows us to guarantee optimal use.
