Fasional Designed Architectural Structure Steel Q355B Grade
Fabrication And Construction Building
Steel structure can be used in fasional designed architectural structure steel
building. Curved sharp of structure steel can meet architect's
Aesthetic elements and multi function of the modern buildings.
It requires easily transported, fast assembled without skilled
labor, without affecting the quality and durability. And design
allows for strength and sturdiness, protection against earthquakes
and wind, and is relatively cheaper when compared to other material
building. Steel structure widely applied to warehouse, factory,
workshop, storage, garage, hangar, etc., also you can add the
partition wall or first floor( second floor) according to
Steel structure adopts Q355B welded H type steel, Q545B steel
square tube, Q235B C type steel and Q235B Z type steel to combine
or build framework. Roof and wall are color compressing corrugated
steel sheet or color steel sandwich panel.
Q355B is one of low carbon alloy steel. Welded H section Q355B
steel with high strength, stonger buckling resistance performance,
can save 10%-15% material, 30%-40% weight of structure in buildings
and 15%-20% weight of structure in bridge than hot-rolled H steel.
Compare to hot-rolled H steel, welded H section steel have
high-accuracy size performance, can be customized.

Advantages of Prefabricated steel Structures construction:
Steel materials have many advantages over other building materials
(such as wood and concrete)
The prefabricated steel structure is manufactured according to
strict specifications and tolerances.
All materials are 100% recyclable.
The steel structure is not easy to warp, bend, twist, or bend, and
is easy to modify and flexible in design.
Steel structure can improve building quality and reduce maintenance
while providing higher safety and resistance.
Characteristics of Prefabricated steel Structures construction:
1. Construction period
In terms of the construction period, the steel structure has
obvious advantages. The prefabricated steel structure building is
speedy because its construction is produced in the factory on the
construction site. Only hoisting and splicing can meet some
manufacturers’ needs for emergency construction and warehouse
2. Environmental protection
After the steel components are processed and transported to the
construction site, the components only need to be hoisted and
welded. There is no water operation, no sand, and a large amount of
dust generated during the whole process, which can reduce
environmental pollution and impact nearby residents. However, the
traditional concrete Buildings can’t do this, which means that
steel structures have done a good job in environmental protection,
the most important aspect of humanity. Besides, the recyclability
of steel also conforms to the concept of sustainable development.
In contrast to concrete buildings, after demolishing, there is a
pile of construction waste.
Steel structure saves construction costs and labor costs more than
concrete. The cost of building a steel structure warehouse is
20%~30% lower than that of traditional concrete buildings, and
steel structure is stronger and more durable than concrete and has
the superior seismic performance.
4. Structural weight
The steel structure building itself has the characteristics of
lightweight. The prefabricated steel structure warehouse walls and
roof are made of light metal building materials, which are much
lighter than the brick and concrete wall ceramic tile roof, which
can reduce the warehouse’s overall weight and does not damage the
stability of the structure.
At KAFA, we have rich experience in delivering the different type
of high quality prefabricated steel structure buildings. If you
have any questions about prefabricated steel structure buildings,
or what is required of you, before your building materials even
arrive or during construction, we are happy to answer them.
