Pre-engineered steel buildings are buildings made of steel structures and fabricated and installed according to pre-specified architectural and technical drawings. The process of making finished products (with a combination of inspection and quality control steps) goes through 3 main stages: Design, Fabrication of components and Erection at the site. The entire steel structure can be produced synchronously and then delivered to the construction site in a relatively short time.
The architectural works that often use this type of house include factories, warehouses, galleries, supermarkets, commercial buildings, high-rise buildings, etc.

Processing Steps of Prefabricated Steel Structure Buildings:
Planning and Design
Prefabricated steel buildings starts with a detailed planning and design phase. During this stage, the project’s requirements are identified, and the building’s specifications are established. Factors such as size, layout, and intended usage are considered to ensure that the final design meets the client’s needs. The planning phase also includes obtaining necessary permits and approvals, as local regulations may impact the building’s design.
Fabrication in the workshop
Once the design is finalized, the components are manufactured in a factory. The use of advanced technology in the manufacturing process ensures that the components are of high quality and precisely engineered for quick assembly.
On-Site Assembly
After the prefabricated components are transported to the site, the assembly process begins. Since the parts are pre-engineered, they fit together seamlessly, making the installation process much faster than traditional construction methods. A skilled team of workers assembles the steel frame, attaches the wall panels, and installs the roofing system. Depending on the size and complexity of the building, the assembly process can take anywhere from a few days to a few weeks.
Steel Structure Building Installation steps:
1.Foundation construction (pre-embedded anchor bolts),
Installing detailed drawing will be offered in advance.
2. Column installation
One worker commands truck crane how to move, 3 ~ 4 workers cooperate with crane to install the steel column, put column to anchor bolt location.
3.Beam installation
After completing the installation of adjacent two steel column, then main beam begin to install.
4.Installing roof & wall purlin
The roof and wall purlin will be installed after finishing column and beam. Bolting the purlin on the main structure.
5.Fixing wall and roof sheet
To fix the wall sheet on wall purlin by self-tapping screw; then fix the roof sheet.
6.Fixing the cover
To install the cover on the corner, eave, window and door opening.
7.Install windows and doors.
