Steel Frame Builders Warehouse / Structural Steel Fabricators For
Metal Buildings
Steel Frame Builders Warehouse / Structural Steel Fabricators For
Metal Buildings. This is a prefab steel structure buildings for
storage chemial production in a industrial area. Portal frame
structure, Welded H-section steel beams and columns are connected
by high strength bolts to be the main steel frame strucutre, EPS
sandwich panel as wall and roof insulation panel. We could contract
the projects such as prefabricated steel structure warehouse,
workshop, storage sheds, garage, hangar, chicken shed, car parking,
showroom, office buildings, gym, dormitory building, high rise
steel residence buildings, oli&gas project, power station,
infrastructure buildings, etc.

Steel structure fabrication in our factory:
The floor space of our steel structre fabrication factory is
35,000㎡, and the workshop area is 20000㎡. We own three light/heavy
H steel production lines, BOX production lines, C/Z purlin
production lines and various types of profiling steel sheet
machines with advanced equipment such as plasma cutting machine.
How to install:
We will design the construction drawing for each project to guide
installation. For abroad project, we could dispatch our engineer to
guide installation on site or our construction team construct 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. |
