Today, pre-engineered steel buildings with advantages such as light weight, easy design, sustainability, fast construction…,helping to save construction costs as well as minimize construction time, so it is increasingly selected and used in civil projects or especially factories instead of traditional concrete products. Through the article below, QSB Steel will share with you the most complete information about pre-engineered steel buildings such as: What is a pre-engineered steel building? Why use pre-engineered steel buildings?
What is a pre-engineered steel building?
Pre-Engineered Buildings, also known as pre-engineered buildings or pre-engineered steel frame buildings, are types of houses built from 3 interconnected components including:
- Main components: columns, trusses, bracing…
- Substructure: C or Z purlins, wall top struts, wall beams…
- Roofing and walls: corrugated iron roof, corrugated iron wall…
A finished pre-engineered steel frame building must be created through 3 stages: design, component processing and erection at the construction site.
The entire structure of the pre-engineered steel building is pre-manufactured, so the erection takes place very quickly. Buildings that often use this type of building can be mentioned as warehouses, factories, supermarkets, display houses, high-rise buildings, commercial buildings …
Structure of pre-engineered steel buildings
Like concrete houses, prefabricated buildings still need the foundation to bear the force of the whole house. Depending on the needs, we can construct shallow foundations or deep foundations; with large construction projects, it will have to be deep foundations to prevent overturning.
In addition to the foundation, the main structure also has other parts such as: the floor; bracing system; columns, trusses… These are very important parts because they are subjected to the entire load.
Substructures will include: floors, walls, partitions; purlins; skylights and canopy roofs… Although they are only substructures, these parts also contribute a part to the construction and completion of the project.
Covering structure, shaping
This is also an important part to create a pre-engineered building; because to complete a project, it is indispensable to cover and shape from materials such as roof corrugated iron, cemboard floor lining, steel floor lining … in order to limit space and protect the house by factors acting on from the external environment.
In addition, the aesthetic factor is also dictated by these covers and shaping.
Why use pre-engineered buildings?
Steel frame structure with a service life of at least 30 years; especially with projects such as high-rise buildings, restaurants, commercial centers … the service life of the steel frame can be designed up to 100 years to meet the durability requirements for construction projects.
Previously, steel structure truss column frames were only used in warehouses, factories or other industrial items… Today, steel structures have been applied to civil projects such as showrooms, restaurants, high-rise buildings, commercial centers …
The cost of pre-engineered buildings can be lower per square meter than traditional construction. Erection costs will gradually decrease for fast and simple erection times.
Pre-engineered steel buildings are green buildings for the environment by cutting CO2, saving energy and being recyclable.
