Long Span Roof Truss Structural Steel Fabrication And Construction Solution

Elegant Appearance Long Span Roof Truss Structural Steel Fabrication And Construction Solution

Steel structures can be used in different functional buildings, including industrial building, commercial building, exhibition hall, showroom, gym, ect. The steel structure can be fabricated into different shape structures to meet different requiremen of the buildings. Meanwhile, elegant and nice cladding material can be applied to the building appearance.

Steel structure adopts Q355B welded H section steel, SHS,CHS, and Q235B C / Z type steel to combine or build framework. Roof and wall are color compressing corrugated steel sheet, Aluminum cladding, glass curtain wall, 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 construction.

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.

3. Price
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.
