The manufacturing process of steel structure components.
11/03/2025
Prefabricated steel buildings primarily consist of pre-made steel components. These structures are characterized by bolted connections, which not only eliminate construction waste during the assembly process but also offer high scalability, unlocking limitless potential for business growth. This article details how steel structure warehouse suppliers manufacture these steel components.
1;Raw materials The steel structure components are fabricated by welding or riveting various types of steel, making the raw material quality critically important. In selecting raw materials, it is essential to choose products from major steel mills, as they offer superior quality and better corrosion resistance. 2;Model Construction Our company utilizes BIM modeling, incorporating wind loads, snow loads, seismic intensity, and other site-specific conditions of the project location. Through rigorous mechanical calculations, we determine the detailed specifications of each steel component, ensuring structural safety while optimizing material usage. Once the model is established, Tekla software is employed to generate detailed material compositions for each steel component based on the disassembled drawings. 3. Steel Cutting Prefabricated steel components are connected with high-strength bolts. We utilize advanced laser cutting machines to process raw materials, which enhances production efficiency and component accuracy. The high-precision positioning of holes in connecting plates—especially at bolt joints—significantly improves installation efficiency. 4. Assembly and Welding The steel columns and beams of structural components typically adopt either portal or truss configurations. Portal structures are formed by splicing steel plates, which are then welded together at the flanges and web using automated welding robots. This method ensures high welding quality, improved processing efficiency, and minimal dimensional deviations. Truss structures, on the other hand, are fabricated by welding steel tubes. Due to the high precision requirements for materials, computer-controlled pipe cutting techniques are employed to guarantee accurate dimensional compliance. 5. Grinding and Painting This is a critical stage in the manufacturing of steel components. Using a shot blasting machine, high-speed steel pellets are continuously projected onto the steel surface, creating uniform indentations. This process enhances paint adhesion and improves corrosion resistance. Important: Paint spraying must be completed within 4 hours after shot blasting. Otherwise, an oxide layer may form on the steel surface, compromising the anti-corrosion performance of the components. 6. Quality Inspection and Spray Marking Upon completion, each steel component undergoes rigorous quality inspections, including checks for weld integrity, positioning of connecting plates, and uniformity of paint coating. After passing inspection, a unique code is marked on the component. The uniqueness of these codes is crucial for ensuring efficient installation. 7. Packing Given the large volume and heavy weight of steel components, our company utilizes modeling to optimize material combinations, effectively reducing shipment volume to save on sea freight costs. Additionally, steel frames are employed to secure the components, ensuring they remain undamaged during long-distance transportation.
