Stangle Cladding Fixation includes design, calculation and production of several types of mechanical fixings and accessories used for cladding purposes. Stainless and galvanized steel are among the various materials used in the fabrication.

Principles for the Fixing of Building Cladding
The fixing systems for building cladding are composed of several elements (angles, expansion bolts, screws, nuts, washers, etc), each of which shall present the appropriate mechanical features in respect to the requirements posed by the specific project.
Any type of cladding, once fixed, is subject to two primary types of load:
– Permanent load (the dead load), due to the weight of the cladding itself;
– Variable load (applied loads), due to the wind, thermal expansions, seismic motions, etc.
Two fundamental types of fixing systems result:
– Load-bearing fixing: to support the permanent load and the vertical components of the variable loads.
– Restraining fixing: to support the horizontal components of the loads. Restraining fixings instead, serve to maintain the slabs in the positions specified by the project design. Thanks to the systems of adjustment with which they are equipped, the absence of perfect verticality in the external surfaces may be easily overcome.
