Australia Peb Building Construction
Description of Peb Building Construction
Peb Building Construction is a steel structure customized according to the customer’s building and structural requirements. All components are produced in the factory and then assembled in a reasonable and orderly manner on the construction site.
The application of Peb Building Construction has many uses, suitable for industrial, commercial and agricultural construction. Compared with other structures (such as wood structure and concrete structure), steel structure has the advantages of high strength, strong durability, strong versatility, and strong economy. The raw materials of the steel structure are welded together according to the specific requirements of the metal structure building to form.

The design of prefabricated metal buildings requires attention
Fire protection design
The disadvantage of steel structure is low fire resistance. Although it will not burn without fire, its mechanical index will change with temperature.
When the temperature reaches 100°C, the tensile strength of steel will decrease and the plasticity will increase.
When the temperature reaches 250°C, the tensile strength of steel will increase slightly, but the plasticity will decrease.
When the ambient temperature reaches 500°C, the strength of the steel will be reduced to a minimum, leading to the collapse of prefabricated metal buildings.
Therefore, when the ambient temperature of the steel structure is higher than 150°C, heat insulation and fire protection must be designed.
Fire protection measures for metal structures:
1) The spray method refers to coating a layer of refractory coating on the surface of the metal structure to form a protective film to increase the fire resistance limit of the steel.
2) The coating method refers to the use of calcium silicate board, concrete, brick and other materials to wind the steel structure, and then form a protective layer to increase the fire resistance of the steel.
3) The water spray cooling method refers to the arrangement of an automatic spraying system on the upper part of the steel structure. In the event of a fire, a continuous water film is formed on the surface of the steel structure to protect it.
2. Set the temperature expansion joint
Temperature changes can cause the prefabricated metal structure to deform, thereby causing thermal stress to the structure. When the plane size of the metal building is significant, in order to avoid high temperature stress, the temperature expansion joint should be set on both sides of the length and width of the metal building.
3. Anti-rust treatment
Anti-rust treatment of steel structure usually applies anti-rust primary and finishing coatings. The number of coating layers and thicknesses are usually determined according to the environment and coating properties. Generally speaking, under the action of natural atmospheric medium, indoor steel structure requires a paint film thickness of 100μm, namely two layers of primer and two pieces of decorative coating. The open-air steel structure or steel structure is affected by the industrial atmosphere, and the thickness of the paint film is required to be 150μm~200μm.
Peb Building Construction Advantage
|Fast construction||Steel structure members are pre-welded, pre-drilled and pre-punched in our factory. Only need to connect by bolts with the accuracy of steel components, no need weld on construction field.|
Only need 5 workers to assemble one steel structure building of 1000 sqm within 25 days.
|Affordable cost||Require less maintenance than concrete building. Averagely, it cost about 50% less than traditional construction. Moreover, 98% of all steel structure can be recycled into new steel products without reducing physical properties.|
|Anti-seismic and wind resistance||Can withstand grade 8 earthquake, wind resistance 300km/h.|
|Long service time||More than 50 years.|
|Health and safety||Steel structure building is manufactured at the factory and rapid installation on the construction site by skilled personnel making steel structure safe. There is very little noise and dust.|
> What is the steel materials used for mainframe?
We apply high strength low calloy structural steel grade Q355B for the mainframe, which ensures the steel building frame strong and durable.
> Why the overall construction cost of Prefabricated Metal Buildings is lower than the concrete building?
The steel material price is higher than concrete structure. But the prefabricated metal building can be constructed fastly and easily with lower labor cost. Thus, the overall cost of prefabrcated metal structure building is much more economical and favorable than the concrete building.
