The longevity and durability of a prefabricated building or factory depend significantly on the project’s structure. It must be solid and carefully calculated to ensure long-term quality. In the article below, BMB Steel will introduce information about typical steel structures used in factory construction.
The role of the structure is similar to a pillar - the main bearing part of the whole building. In construction, the structure will be divided into components, and they are connected together to form the frame of the work, such as floors, beams, columns, walls, and foundations...
Steel is made from an alloy whose main composition is iron (Fe), with carbon©. Carbon accounts for 2.14% by weight. Steel is a material with high strength, durability, and low ductility. Thus, it is preferred in construction. The outstanding features of steel are light-weight, good force resistance, easy assembly conveniently.
Therefore, a steel structure is a type of structure made of high-strength steel material. Primarily, steel structures are used in large-scale constructions such as factories, companies, etc.
The frame structure consists of beams and columns. In which the beam transfers the load from the floor to the roof and columns. It can be up to 18cm in size and range from 3m - 9m. Steel beams connect beams to beams or beams to columns.
In the form of a mesh structure, the steel materials are assembled to create a grid shape. The grid roof creates the dome shape. This structure is often used in the design of large span buildings to make dome greenhouses for agricultural or industrial production activities.
In this construction structure, builders will use high-strength steel wire to place concrete structures. If an impact causes the steel cable to be stretched, it will reverse to resist the force from external influences.
In large-scale factory projects with great production lines, beam bridges are designed to limit laborers for fast and light transportation. The beam bridge is installed with a loader crane. We can also use two pillars to install the beam bridge.
The cable-stayed bridge in the industrial factory is used to be anchored on the pylons of the roof. The cables will be connected at a pillar point of the building and parallelly connected down to the bridge deck with the tower shape in the form of a harp.
The truss structure consists of linked steel bars, which gather together and form knots. Bolts, rivets, or welding connect the rods.
The arch bridge steel structure has an abutment at the end of each side. The steel frame has a dome shape. The bridge’s weight and the load will be converted into a force system that is pushed horizontally and transferred to the two sides of the abutment.
The arch steel structure has a long-span structure, so it is very suitable for buildings such as stadiums or factories. This structure consists of three main bars linked together in a zigzag pattern. It is used with round and galvanized steel tubes.
This structure is built with many horizontal or diagonal steel bars. The main components are the tower steel frame, slings, main cables and anchors, and the road surface. The main cable part is the supportive point to hang the anchor cables, connect and support the bridge deck. The main cable is parallelly on both sides of the bridge deck. It is connected to the top of the bridge's tower frame.
A Truss bridge is constructed with various steel frames and parallel frame borders, polygonal or parabolic edges. The bars on the bridge are connected to each other by rivets or anchor bolts. The ground surface is crossed, horizontal steel bars, which are made with reinforced concrete material.
Step 1: Select raw materials
Step 2: Check the material
Step 3: CNC and hydraulic cutting
Step 4: Manual welding
Step 5: Automatic welding
Step 6: Hydraulic breaker
Step 7: Straighten the components
Step 8: Grinding
Step 9: Non-destructive welding test
Step 10: Painting
Step 11: Clean and prepare the surface
Step 12: Complete and transport to the construction site
Apart from steel, concrete is also used in building construction. Each type of structure has its own advantages and disadvantages. Below, BMB Steel will share with you a comparison table:

The steel structure in factory construction has many advantages. Some of the remarkable ones are:
For the above reasons, when building warehouses or pre-engineered steel factories, people often choose steel structures to ensure quality and durability.
The article above is all about steel structure in factory construction. Hopefully, construction owners and contractors can compare to choose the right solution for their projects.
