3. APPLICATIONS OF STEEL STRUCTURES 4. QH PLUS'S ADVANTAGES IN STEEL STRUCTURE PROCESSING SERVICES

With many useful and flexible features, steel structures are widely used PROFESSIONAL AND EXPERIENCED ENGINEER TEAM
in many types of buildings and construction works, such as:
QH Plus has more than 300 steel buildings staffs including specialized engineers,
qualified workers, site supervisors with many years of experience in steel structures.
INDUSTRIAL & CIVIL BUILDINGS In addition, our experts provide comprehensive recommendation and budgeting
for all related activities of the project including design, production, transportation
The processing and erection of industrial & civil buildings by steel structures and installation.
has many advantages such as speeding up the progress, high durability
and meeting all the project’s functions.
ON SITE SUPPORTING SERVICES

We always follow to support customers from the time the contract is signed until the
LARGE CLEAR SPAN CONSTRUCTIONS end of the project; including:
- Guiding how to open and unsealed products in the right order
Steel structures are also applied in projects which need large area and - Supporting material inspection
use space such as commercial centers, stadium roofs, airport terminals... - Guiding the contractor how to store materials
to ensure aesthetic and technical requirements of those construction. - Safety advice and technical assistance during the erection
- Receiving all requests, feedback from customers and timely propose effective
solutions
PIPE RACK SYSTEM

For this type of construction, the processing assembled modules by steel QUICK AND FLEXIBLE DELIVERY
structures will be more flexible according to investor's purpose such as:
pipe rack, pipe bridge... The delivery process is carried out by QH Plus's tranportation & logistics team.
Therefore, the delivery time is faster and meet the construction timeline. QH Plus
has 14 tractor trailers (cart load: 31.6 tons, 25.6 tons) and 02 crane trucks (12.9
tons) with experienced drivers who are well-trained in the skills of loading and
TRANSPORTATION CONSTRUCTION
unloading in the right manner for each type of goods; Therefore, the product
quality is guaranteed and not affected by external factors.
In terms of fabrication, structural steel is easy to be processed such as
cutting, punching, welding, beveling,...This helps the construction can
meet architectural requirements as well as load bearing capacity, such as:
bridges, roads, toll stations, advertising billboards,...

AUXILIARY WORKS

Besides, steel structures are widely used for many auxiliary structures such
as piles, kingpost, bracing system,...

SUPER HIGH-RISE BUILDINGS

With Multidirectional wind loads acting on super-high-rise buildings,

it is necessary to have the building core system made of complex steel
structures such as transfer beams, steel core, STEEL LINTELs,...

And many other applications of steel structures such as power poles,

broadcasting towers, drilling rig system,...
