There are two main types of steel plate: Q235 and Q355.

Q means “bend”, it is for the yield strength.

Q235 is the minimum yield strength 235 Mpa.

Q355 is the minimum yield strength 355 Mpa.

Q235 and Q345 as the popular construction steel materials

They are divided into 4 grades, ABCD. Such as Q235A , Q235B, Q235C, Q235D.

ABCD refers to the impact test grade. A means that it has not been impact tested. B means that it has been impact tested at 20 ° C temperature. C means that it has been impact tested at 0 ° C temperature. And D means that it has been impact tested at low temperature of -20 ° C.

Q235A&Q235B, Q345A&Q345B are the most popular.

Q345 is mainly used for main steel frame. Like column, beam, wind speed resistant column, crane girder...

Q235 is mainly used for secondary steel frame. Like tie bar, brace, vertical/horizontal support...

The choice of material can be according to the design of the structure of your specific circumstances. For example, if the structure is intensity control structure, Q345 can be considered. If the structure is stiffness control structure, you can choose Q235. The price Q345 is a little higher, but because of its high strength, the material can be saved. And the price difference is not great.

A steel structure is a metal structure made of structural steel members that are connected to each other to carry loads and provide complete rigidity.

Cladding system in steel structure construction plays an important part. It affects the whole building's energy consumption.

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.
