An excellent solution for storing wooden products and semi-finished products which naturally dry and re-dry when stored in such manner and are protected from the external factors, i.e. sun, wind, rain and snow. The sides are made of perforated tarp, so they allow constant air flow and, if necessary, they also have the option of rolling.

The structure is double – made of hot-dip galvanized tubes that are reinforced in a manner that the black tube with phi 54mm/4 mm is pressed into the outer galvanized tube with phi 60mm/2mm. The cross tube is also reinforced. The sides go into a triangular lattice to the cross tube which makes for a strong structure. The foundation of the structure can be anchored using wedges in the ground or asphalt or securing into concrete.

What is the price of Arosa Grande structures per square meter?

What is the estimated time of delivery of the structure?

The time of delivery is determined on case-to-case basis – depending on the current workload of our company and the size of the structure. The usual time of delivery for structures is from 45 to 60 days.

How long is the warranty and lifespan of the structure?

The warranty period for PVC cover is 5 years.

According to our experience, lifespan of the structure is not limited, since the structural components are galvanized and can be used for up to 30 years without any problems.

How to prepare the terrain?

The terrain should be as flat as possible. It is necessary to level the terrain with a maximum drop of up to 2% in width and height. The tunnel can be placed on compacted sand, crushed stone, asphalt or concrete. The required thickness, or load capacity of the soil, depends on the width, load capacity of the structure and the customer’s requirements.

Which colour is recommended for the PVC cover?

In most cases, we recommend a white translucent tarp in the middle of the roof, while the rest of the structure is green, grey or white. This combination allows sufficient sunlight within the structure without additional artificial light, thereby reducing operating costs. Other colour combinations from the manufacturer’s range are also available.

Is it possible to add an advertising sign or logo onto the structure?

We can add an advertisement (at an agreed price) if the customer sends us an advertising sign or logo in a suitable digital format. After we get the logo and the preferred dimensions, we create a draft and send it to the investor for the approval.
