Great experience with tunnels covered in canvas, has also led Tecnoengineering to offer a version with corrugated sheet metal cover, with or without inner "condensation absorbing" layer, in a curved roof version or with insulated metal panels in the gable roof. These structures allow a high volume of storage for goods and / or shelter for large machinery, with greater protection from malicious intrusions. Also made with "copper look" roof that blends in perfectly even in environments with landscape restrictions. Anchored to the ground without concrete foundations or with special plates fixed on a suitable floor. Calculated and certified standard loads: Snow 360 daN / sqm. - Wind 120 km / hour.
