| | | | | Belts are mainly used as a support element for roofing or in some cases in very light floor structures. | | | | | | 
| | | Z BELTS are linking elements that are positioned at a 90 degree angle in relation to the trusses and have a geometry that generates asymmetry in relation to the horizontal and vertical central axis, which allows load concentration in the middle of the section, in other words we obtain higher inertia around both main axis.
