Prefabricated buildings are structures with a rectangular plan and big spans. Particularly, structures are equipped with main and secondary supporting elements and other components.
The first insulated steel buildings date back to the fifties and are useful in the industrial sector thanks to their resistance and versatility. They can be used as coverings for stables and crops in the agricultural sector, as expansions of a department in the food industry, as tool sheds and as sports coverings.
Regardless of the intended use, an industrial covering is made of beams and pillars (main elements) and slabs, panels and tiles (secondary elements). Some structures are equipped with other components, such as beams to be placed on the sides and in the middle of the structure to support the covering.
The covering can be manufactured with different materials, waterproof sheaths, a PVC curtain, sandwich panels or heat-insulating panels.
Cost per square meter of a prefabricated buildings
The cost of prefabricated buildings may vary according to different factors, concerning the materials used for the construction, the sizes and the intended use.
. Prices of prefabricated industrial buildings are different if you choose to build a concrete, iron, steel or insulated structure because the materials used are different and the initial cost of the raw material is not the same.
. At the same time, the labour cost has an impact on the final price of the structure. Another key element defining the price of a prefabricated building is the size. A large structure is obviously more expensive: you need more raw materials, construction times are longer and the labour cost is higher.
Among the factors leading to an increase of the final price, there are particular structural characteristics, including snow load, wind-resistance or the use of other storage materials, which are necessary in some installation places.
The intended use affects the final price in a significant way, because different construction techniques must be taken according to the customer needs. Furthermore, there is the possibility to perform waterproofing and heat insulation treatments. It is not easy to estimate the final cost of a prefabricated building, but it is useful to identify which structural elements may increase the price:
- structural elements (beams, slabs, pillars, tiles and additional accessories);
- foundations (including crossbeams);
- external elements (car shelters, portals…).
Giesse Logistica has been operating for years in the construction of industrial structures. Prefabricated buildings by Giesse Logistica cost around 200 euros per square meter.
Types of steel buildings
There are many different types of prefabricated buildings, whose characteristics may vary according to the material used for the construction. Particularly, prefabricated structures can be divided into two categories according to the construction materials: heavy and lightweight prefabricated buildings.
Concrete structures are part of the first category, while metal structures (such as cast-iron or steel buildings) are part of the second group.
Listed below are the different types of installation:
- Prefabricated concrete buildings. Concrete structures have some structural advantages because they are resistant and suitable for covering big spaces. They withstand fire, corrosion, bad weather conditions including wind, snow and hail and frost. Concrete prefabricated structures do not require specific maintenance works. Besides, concrete structures represent the best solution for the seismic risk areas because they have high aseismic properties. On the other hand, a concrete building cannot be removed easily; construction times are longer and it is more expensive. However, this structure represents the best solution for industrial, commercial and logistics sector.
- Prefabricated steel buildings. Steel buildings are part of the first category, such as lightweight buildings, because the materials used are very lightweight. One of the distinguishing features of these structures is the high versatility; in fact, they can have many intended purposes. Steel is a very lightweight material and allows to build customizable structures with regards to the dimensions and the shape. It can be installed even on rough terrain or can be used as an extension of an existing building. Prefabricated steel buildings have a high mobility; they can be assembled and disassembled easily and the material can be resold as scrap once the structure is dismantled. Steel is an easily accessible material and does not require long construction times, so it is possible to install prefabricated steel structures in a short time.
- Prefabricated cast-iron buildings. Prefabricated cast-iron and steel buildings are part of the lightweight prefabricated structures because the materials have no excessive weight. Cast-iron does not require expensive maintenance works because it can withstand any weather condition. It is lightweight, seismic and fireproof. Anyway, one of the most important features of cast-iron is its lightness so it is widely used as an extension of existing buildings without supporting beams.
- Prefabricated insulated buildings. Prefabricated insulated buildings are a separate category because they can be made of any material. Besides, sandwich panels ensure the best acoustic and thermal insulation. This type of structure is the best solution for all those areas where it is necessary to insulate spaces from heat, cold or noises. For this reason, insulated buildings are often used in sectors where it is important to maintain an optimal temperature, such as food and pharma industry.
Prefabricated buildings and their fields of application
A prefabricated building can be used in several sectors. Concrete structures are used as extensions of existing departments in the industrial field, as well as storages for large products (think about the nautical sector).
Besides, prefabricated insulated structures are widely used in the agri-food sector for storing foods and cooking products. In this sector, they can also be the ideal solution for protecting livestock.
These prefabricated structures are highly customizable, so it is possible to use them even for sheltering chickens and agricultural crops. Prefabricated agricultural buildings can be used as tool sheds or equipment storages, too.
Among other fields of application, prefabricated structures are used to storage goods and to shelter the loading and unloading areas in the logistics sector.
Lastly, prefabricated structures are widely used in the sports and commercial sector; they represent the best solution for covering sports facilities or as structures hosting meetings and conferences.
