The most modern and complete structureon the market can be customised to meetspecial requirements. Widths available vary from 12 to 42 m. Twin-membrane structures available to ensure energy savings duringthe winter and comfortable temperaturesduring the Spring and Autumn. Our patented "Baraccatura di Testata" is available as anoptional on all versions. This enablesopening even on the short sides andcomplete temperature comfort even in thecorners. Our technical office manages the design and manufacture of our arched,galvanised steel structures. This office is responsible for project calculations and for preparing detailed workshop and manufacturing drawings. All structural steel work is designed and manufactured for use with fabric membrane coverings to ensure that the structure and its covering are securely connected and assembled. All structures are designed and manufactured in accordance with current regulations and the reference standards listed below. THEORETICAL LOADS: > Own weight.Snow overload:This is the snow load at the height above sea level of theinstallation site.Wind overload:This is the wind load for the installation site with reference tothe Roughness Class and the Exposure Category.The calculation values are chosen on the basis of the circular n 156AA.GG./STC of 04-07-96 para C.7.6 concerning open constructions.Fabric pretensioning:This is the two-way axial prestressing exerted by the fabricmembrane cover on an arch at a constant load; this value is notrequired by current legislation. Design standard U50.00.299.0 of November 1996 Ж Tent structures, tension structures, airsupported structures Instructions for calculation, construction,testing, use and maintenance.Seismic overloads:The seismic deformations in our arched structures do notendanger the connections between structural elements. The movement of foundations specified in the standards doesnot significantly modify loading and it is not therefore necessary size="-1">

The following materials are used in our arched steel structures:Special rods and plates:FE 510 B FN (EN 10025).Tie bolts:FE 430 B ֖ FN (EN 10025). Structural steelwork:FE 360 B FN (EN 10025). Bolts and nuts:Class 8.8 or higher Welding electrodes:44 Class 4 B (UNI 5132) orequivalent.Concrete:Rck > 250 daN / cmֲ. Reinforcing steel for foundations:FeB 44K, cut to size. TREATMENTS: Metal parts are hot-dip galvanised in a molten zinc bath. This ensuresthat open profile is suitably galvanised on the inside and the outside.Threaded parts such as bolts are electrolytically galvanised. >
