Steel Structure Buildings:
Steel structure is the materials used in various steel
constructions and it has specific shape. Based on the project’s
unique specifications, the steel components can assume various
shapes, dimensions, and thicknesses, produced through hot or cold
rolling processes. In contrast, others are created by welding flat
or curved plates together.
Steel structures typically feature shapes such as H profile,
I-beams, hollow structural sections (HSS), channels, angles, and
plates.
The main type of steel structure are the frame structure, the truss
structure, the grid structure, the arch structure, and the portal
rigid steel frame.
Pre-engineered steel buildings are buildings made of steel
structures and fabricated and installed according to pre-specified
architectural and technical drawings. The process of making
finished products (with a combination of inspection and quality
control steps) goes through 3 main stages: Design, Fabrication of
components and Erection at the site. The entire steel structure can
be produced synchronously and then delivered to the construction
site in a relatively short time.
The architectural works that often use this type of house include
factories, warehouses, galleries, supermarkets, commercial
buildings, high-rise buildings, etc.

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 Advantages:
Steel structure is a popular and reliable choice for a wide range
of construction projects due to their structural integrity, from
commercial and industrial buildings to bridges and other
infrastructure developments.
Steel has a high strength-to-weight ratio, which is very strong for
its weight, and is much higher than other common construction
materials, such as concrete and wood. This means that steel
components can be made very lightweight without sacrificing
strength.
Ductile steel structures can absorb more energy before failure than
brittle structures. This makes them ideal for applications
subjected to high-impact loads, such as in earthquake-prone areas
or industrial settings.
Prefabrication and ease of assembly of steel structures lead to
faster construction times.
The steel structure is recyclable, making it an environmentally
friendly choice.
Low maintenance requirements of steel structures contribute to
long-term cost efficiency.
Steel fabrication can be easily modified or expanded.
Properly designed steel structures can provide high fire
resistance.
