Multi storey structural designed steel framework building construction
Multi storey structural designed steel framework building construction is a building structure made of steel, including internal support and external enclosure structure. The steel frame is made of a portal steel frame, including steel columns, steel beams, and bracing. There is a platform designed hanging below the roof beam. The portal steel frame and the external enclosure structure constitute an enclosed building structure with sufficient strength to withstand severe weather such as strong wind, rain, and snow.
Metal structures are processed with cut, welded, drilled, and painted in the workshop, and then transported to the construction site, often referred to as prefabricated structures. The prefabricated steel structures are no need to be welded on-site, and each component only need to be fixed with bolts, which is convenient and quick to install and save labor. Five main types of structural components make up the steel frame-tension members, compression members, bending members, combined stress members, and their connections.
||Length x Width x Height , Floor height
||Fortal frame, double slope, single span, partial mezzanine hanging below the roof beam.
||Concrete and steel foundation bolts
|Column and beam
||Welded H steel Q355B, all bolts connection, Variable cross-section beam and columns
||X type bracing made from angle steel or steel bar
|C or Z purlin
||C/Z section steel with size C160-300 or Z160-300
|Roof and wall panel
||Single colorful corrugated steel sheet;
sandwich panel with insulation of EPS, Rock wool, glass wool or PU
||Semi-transparent skylight belts, Ventilators, down pipe, gutter,doors,windows, etc
||Painting or hot dip galvanized
||Nude or packed on steel pallet and then loaded into 40'HQ/OT
Wall and roof system:
The roof panel is usually a single continuous length from the eaves to the ridge line for portal frame buildings.
Wall panels are usually the continuous length from the bottom wall to the eaves of the building.It is usually a corrugated single-color metal sheet with a thickness of 0.4mm-0.6mm. For a factory building that requires thermal insulation, you can choose to use sandwich panel.
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.
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.
