Pre engineered Steel Structure Buildings Fabrication And
Construction
ADVANTAGE OF PRE ENGINEERED STEEL STRUCTURE BUILDINGS:
The construction mode of Pre engineered Steel Structure Buildings is design → factory manufacturing → on-site installation, compared
with concrete buildings, it has below advantages:
| 1 | Steel structural material has high strength and light weight | The steel structure has high strength. Compared with the concrete
structure, the steel structure beam and the column cross-sectional
area are small, which can increase the effective use area.
Generally, the cross-sectional area of the high-rise steel
structure column accounts for about 3% of the building area, and
the cross-sectional area of the high-rise concrete structure
accounts for 7%-9% of the building area. |
| 2 | Steel structure construction speed is fast | Most of the steel structure is produced in the factory and
transported to the site for integral assembly by welding or
bolting. It can be used all day, because the steel structure itself
can be used as a load-bearing structure for the construction load
to reduce the formwork during construction, thus not only reducing
costs, but also greatly speeding up Construction speed. The
construction speed of the steel structure is about 1.5 times that
of the concrete structure. |
| 3 | Convenient pipeline layout | In the structural space of the steel structure, the truss type
member or the member having the cavity can be used, so that the
arrangement of the pipeline is convenient, and the replacement and
repair of the pipeline is convenient. However, if a concrete
structure is used, the beam should not be opened, and the pipe
generally passes under the beam, thereby occupying a certain space.
In the case of the same floor height, the floor height of the steel
structure can be smaller than the floor height of the concrete
structure, which can reduce the area of the outer wall. |
| 4 | The steel construction environment is less polluted | When steel structure is constructed, sand, stone, soil, cement and
other materials are rarely used, and pollution problems such as
dust flying, waste accumulation and noise are avoided from the root
wood. |
| 5 | Steel structure construction conforms to sustainable development
policy | The steel structure industry is a green-bag environmental
protection construction industry. Its utilization of resources and
energy is relatively reasonable, and has little damage to the
environment. |
