Structural steel fabrication plays an important role in providing high-quality steel components such as steel trusses, steel beams, and steel frames to meet the demands of residential, commercial, industrial, and infrastructure construction projects. Join Newinds to explore the details of structural steel fabrication in the article below.
What is structural steel fabrication?
Structural steel fabrication is the process of cutting, bending, and assembling raw steel to create a complete steel structure. Raw steel transforms into specific shapes and sizes to match the project’s design requirements.
Key steps in the structural steel fabrication process
The process of fabricating structural steel is relatively complex, requiring extensive knowledge, experience, skills, and resources to produce high-quality products that ensure safety. The key steps include:
-
Design
First, technical 2D drawings are created to model detailed specifications, structural components, and calculate potential errors during fabrication and installation. This step often involves the use of Computer-Aided Design (CAD) software to ensure design precision.
-
Material Selection
The procurement team analyzes the Bill of Material (BOM) to select materials that meet the project’s requirements. Critical factors such as load-bearing capacity, weight, and operating environment are carefully considered. Once finalized, the steel is delivered to the factory for fabrication.
-
Cutting
The steel is modified to the exact dimensions and drilled to create necessary holes as specified, using tools like CNC machines, plasma cutters, saws, or lasers.
-
Bending
Steel sections are bent to specific angles using press brakes or rolling machines to achieve the desired shapes.
-
Assembling
The cut and shaped steel pieces are temporarily assembled and fixed into position, preparing them for subsequent steps.
-
Welding
Steel components are permanently joined using welding techniques such as MMA (Manual Metal Arc) or MAG (Metal Active Gas). Welding may be performed manually or using machines, and the process is closely supervised by experienced engineers to ensure durability.
-
Surface Treatment
The steel is coated with protective layers, such as galvanization or painting, to prevent corrosion and enhance durability.
-
Quality Control
After each fabrication stage, the steel components undergo stringent quality inspections to ensure they meet the required standards and specifications before being transported to the construction site for assembly.
-
Shipping
Structural steel will be packed and transported to the construction site. It is essential to thoroughly check the quantity before shipment to avoid shortages upon delivery. Additionally, steel components must be arranged logically to ensure safety and quality during loading and transportation.
Advanced steel fabrication techniques in Vietnam
Vietnam’s steel structure manufacturers are known for their advanced technology and machinery, which deliver high-quality steel products with precision and accuracy. Key techniques include:
