Steel Structure Introduction:
Steel Structure Frame |
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. | Hot-rolled H-section steel is an economical section high efficiency
profile with more optimized cross-sectional area distribution and
more reasonable strength-to-weight ratio. It is named H steel,
because its cross-section as the English letter "H". Hot rolled
H-section steel has the advantages of strong bending resistance,
simple construction, cost saving and light weight. So now it has
been widely applied in steel structure. |
Roof and Wall Cladding System |
Cladding system in steel structure construction plays an important
part. It affects the whole building's energy consumption. | Steel sheet, which is the cheapest without any insulation. EPS Sandwich Panel, which is good insulated but flammable. Glass Fiber Sandwich Panel,which is with general insulation but
non-flammable. Rock Wool Sandwich Panel, which is with good insulation and is
non-flammable. Pu sandwich Panel , which is most expensive, with prefect
insulation and non-flammable and waterproof. |
Connecting Bolts |
In the site installation, the steel structure components normally
adopt bolt connection for the quick and easy processing. In order
to meet the bolt connection requirements, the manufacture needs to
make holes in the corresponding positions on the surface of the
steel components. And the holes' position and dimension must meet
the specification requirements. If the installation has trouble of
unqualified holes on the site, it will needs the manufacturing
rework. It will cause the extra economic losses. |
Steel Structure Widely Appication:
Top ten markets for steel structures |
Housing Construction | Residential, office, public facilities (shopping malls, cinemas,
stadiums, exhibition centers, aircraft terminals, train and bus
platforms), factories, etc. |
Tower Mast | Transmission lines, communications, radio and television, light
poles, wind power poles, etc. |
Container | Petrochemical equipment, storage tanks (like oil, gas, grain), etc. |
Steel pipe | Seamless welded steel pipe, used for steel pipe structure; Solid material transportation pipelines(like water, gas, oil and
other coal slurry), known as the fifth largest transport |
Ocean Engineering | Piers, docks, oil platforms, marine structures, artificial islands,
etc. |
Bridge | Highways, railway bridges, urban light rail, overpasses, trestles
and combat readiness bridges |
Municipal facilities | Guardrails, signs, billboards, light poles, shelters, parking lots,
trash cans, barrels, etc. |
Mechanical equipment | Complete sets of equipment for construction machinery, elevators,
cranes, cable cars, rolling mills, cold bending equipment,
amusement facilities, petrochemical, metallurgy, light industry,
home appliances, etc. |
Household items | Doors and windows, escalators, furniture, light steel keels, warm
text and decorations, etc. |
Plantation facilities | Various greenhouses, three-dimensional planting, automatic
sprinkler irrigation, greening facilities, 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.
We own more than 20 engineers who have abundant experience for
various types buildings. Before design, all requirements will be
collected from clients. The design will obey the requirements and
pass the calculation check by the architectural soft, such as CAD,
PKPM, 3D3S etc.
For the initial planning, we will design the construction blueprint
after confirming the client’s requirements details. With the check and feedback from the
clients, we will make the revise if possible.
After the confirm, we will make further steel structure detailed
drawing to prepare the production. This will still be offered to
the clients to confirm. Double check will guarantee the building
with correct details.
If necessary, finial 3D model will be offered if needed.
Firstly Design Details Confirm before the quotation:
Free Custom Design for you |

Certification | CE, SGS,ISO9001:2008,ISO14001:2004 |
Wall and Roof Options | Different coating and colors available |
Paint Options | Alkyd , Epoxy zinc, Hot dipping Galvanize |
Finally Loading and Shipment after the production:
Normally for steel structure, we will pack them by the steel
pallet. Packed processing outside of the loading container is
easier to operate, easier to adjust and more efficient to use the
container limited space. At the same time, steel pallet will also
protect steel components to reduce the conflicts and surface
coating abrasion.
The steel pallet will be loaded by closed containers, like 20'GP, 40'HC.
If clients wants to save the steel pallet cost, the steel components is better
to be loaded into open top container one by one, like 40’OT.
Closed container:
Advantage:Cheaper shipping cost,all members be packed together and reduce friction, the surface coating of steel members will be much better protected;
easy unload
Disadvantage:steel pallet cost
Open top container:
Advantage:easy to load &unload; save steel pallet cost
Disadvantage:higher shipping cost, aleak and few quantity to load
Steel structure building installation on site:
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.
