The Detan® stay rod system is made of several basic elements and accessories, with which it is possible to resolve distinct problems in tensile structures. The basic pieces are forged out of steel alloyed with carbon and through a molding process developed by the company. The minimum requirements necessary to assemble a stay with this system are a rod with a circular section, two end fittings and two anchor plates.
—Rods: rod ends are threaded in opposite directions, one left-handed and the other right-handed. The thread direction is indicated on each end fitting, and the connection is therefore rapid and simple. This prevents faulty assembly and requires no turnbuckles. Maximum rod length is 6 m, with diameters from 6 to 60 mm.
—Plugs: with a color-coded threaded end, they only fit onto one end of the rod. The system is supplied with pins, safety rings and nuts, designed to form an aesthetically and mechanically perfect connection to the rod. The nut, once it has been tightened, acts as a locking nut that prevents loosening.
The anchoring is completed by a plate with pin, to which is firmly attached the end fitting by two lateral rings. There are several different models of the Detan® tension rod, depending on the size and admissible load on each piece. Available accessories are rod couplings and four point anchor disks, specific to each model.
After assembling the stay, the threads completely disappear, which combines with the tear-drop shape of the end fitting to make the joint imperceptible.
