Q355B Steel Structure Multi-Span Warehouse/Tire
Factory/Prefabricated Building
With the development of the prefabricated steel structure
construction industry, more and more wall and roof insulation
materials are applied, such as aluminum-zinc color plates, aluminum
magnesium manganese plates, aluminum-plastic plates, aluminum
plates, etc. These new materials have smooth appearance and
structure Exquisite, to create a beautiful and comfortable working
environment for customers; excellent performance: unique dustproof,
antistatic, antibacterial, sound absorption, sound insulation and
fireproof performance; factory prefabrication: standardized
production, modular construction, improve construction efficiency,
reduce human impact; Customization: The system is well-designed and
flexible, and can meet the professional needs of different
industries.
Qingdao Ruly Steel Engineering Co.,Ltd is a professional steel
structure fabrication and construction company for light and heavy
steel structure project. Our service include design, fabrication
for all the steel structure components and insullation panel,
installation on site.

Advantages of prefabricated steel structure buildings:
| 1 | Light weight, high strength and large span: | Although the density of steel is larger than other building
materials, its strength is very high. Under the same force
condition, the steel structure has small weight and can be made
into a structure with a large span. |
| 2 | Short construction period | The main components of the plant are prefabricated in the factory.
After being transported to the site, the installation is carried
out, and the assembly work is convenient. |
| 3 | High fire resistance | When the surface temperature of steel is within 150 °C, its
strength changes little. When the temperature exceeds 150 °C, its
strength drops significantly. Fire-retardant coatings are generally
applied to the surface of the steel structure to form a protective
film that enhances the fire endurance of the component. Of course,
the reasonable division of the fire compartment is also very
important for the use of fire shutters. |
| 4 | Anti-seepage and waterproof | the infiltration of rainwater is mainly through nodes or gaps. To
prevent seepage and waterproof, it is necessary to use concealed
fixing after the sealing gasket is used at the screw mouth, and
sealant or welding treatment is used at the joint of the plate. It
is good to use a long plate to eliminate the lap joint, and the
swell is tightly waterproofed at various joints. |
| 5 | Sound insulation | Fill the metal roofing layer with soundproofing material (usually
glass wool), or apply heat-reflective coating on the metal tile
surface. |
| 6 | Ventilation and cooling | Generally high-architecture workshops, no extra-high-power heating
equipment, personnel are not very dense, and there is no odor or
dust. The roof fan + gas building can be used. For steel structures
with higher structure and larger span, the best is to install a
large exhaust fan on the roof to exhaust the air; to form indoor
negative pressure; press a lot of fresh air into the workshop from
the surrounding of the workshop to form air. Convection; the effect
is better. |
| 7 | Good lighting | Install lighting panels or lighting glass at specific locations on
the roof. Considering the service life of the sunroof and the
coordination of the roof panels, the joints must be waterproof.
