Six factors affecting the cost of prefabricated steel buildings.
1: Structural form of prefabricated steel buildings
Usually, the structural forms of prefabricated steel buildings are divided into: Portal Frame,Steel Frame,Truss,Grid .
The corresponding materials and processing techniques used in various structural forms will affect the cost of the building. How to choose a reasonable structural form for prefabricated steel buildings?

2: The geographical factors of the location of the prefabricated steel buildings.
In addition to bearing its own weight, prefabricated steel buildings also have to bear additional loads, including: live loads, wind loads, snow loads, air corrosion, earthquake forces, etc. If the area where the building is located has to bear the above-mentioned multiple additional loads, it is usually necessary to increase the size of the materials, spray high-quality anti-corrosion coatings, add structural supports, etc. to ensure the safety of the buildings.
3: Selection of prefabricated steel buildings envelope materials
Prefabricated steel buildings usually use single-layer steel panels and sandwich panels as wall and roof materials. In hotter and colder regions, sandwich panels are often used to maintain temperature and humidity inside the building.
4: Lighting and ventilation requirements for prefabricated steel buildings
The area of prefabricated steel buildings is usually relatively large, and lighting and ventilation can save enterprises’ electricity expenses to a certain extent. These building functions are usually achieved by increasing the number of wall windows and roof ventilation windows.
5: Transportation of prefabricated steel buildings components.
The components of prefabricated steel buildings are large in size and volume, and shipping fee is an expense that cannot be ignored. It is particularly important to choose reasonable connection nodes and packaging methods. Using more bolted nodes can reduce transport volume by 20%.
6: Construction and installation management of prefabricated steel buildings
Professional installation and construction management is a very important factor. For example: the installation sequence of components, the selection of lifting machinery, etc. More professional construction and installation management greatly improves installation efficiency, reduces the use time of hoisting machinery, and reduces installation costs.
