Metal Welded H Beam

What is the welding of H-beams：

1. Material Preparation: Select steel plates that meet the requirements, typically flat and uniform in thickness.

2. Cutting: Use CNC cutting machines or shearing machines to cut the steel plates into web plates and flange plates according to the design dimensions.

3. Assembly: Assemble the web and flange plates into an H-shaped structure as per the design specifications.

4. Welding: Use automatic welding equipment to weld the assembled H-shaped structure, ensuring the quality of the weld seams.

5. Correction: Correct the welded H-beam steel to ensure its straightness and dimensional accuracy.

6. Inspection: Conduct quality inspections on the finished product, including appearance, dimensions, and weld flaw detection.

7. Coating (Optional): Apply rust-proof treatment or coating to the surface of the H-beam steel as needed.

Process Characteristics：

1. High Flexibility:

   The welding process demonstrates exceptional flexibility in the production of H-beam steel. It can skillfully combine steel plates of different materials and specifications according to various design requirements, successfully manufacturing H-beam steel in a wide range of special sizes. This perfectly meets the diverse needs of engineering projects. Regardless of how unique or complex your project requirements may be, our advanced welding technology allows us to tailor-made H-beam steel products specifically for you, ensuring the smooth progress of your project.

2. Relatively Low Equipment Costs: 

   Compared to the large-scale dedicated rolling mills required for the rolling process, the equipment needed for the welding process, such as welding machines and fixtures, has relatively lower costs. By choosing our welded H-beam steel products, you not only receive high-quality materials but also effectively control costs, maximizing economic benefits.

3. Significant Impact of Weld Quality: 

   However, the welding process places extremely high demands on the technical skills of operators, as weld quality is significantly influenced by human factors. Improper settings of welding parameters or mistakes made during operation can easily lead to welding defects, which in turn severely affect the overall performance of the H-beam steel.

   In our production process, we have an experienced and highly skilled professional welding team that strictly adheres to standardized operating procedures, ensuring that every weld meets the highest quality standards. This guarantees the superior performance of our welded H-beam steel products.

Metal Rolling H Beam

What is the rolling of H-beams：

1. Material Preparation: Select steel billets or plates that meet the required standards as the initial material.

2. Heating Treatment: Heat the steel billet to a high temperature to make it malleable, preparing it for subsequent rolling processes.

3. Rough Rolling: Use multiple rough rolling passes to preliminarily form the heated billet into a semi-finished product resembling the shape of an H-beam.

4. Finish Rolling: Employ precision rolling mills to accurately roll the semi-finished product into the final H-beam shape.

5. Cooling: Allow the rolled H-beam steel to cool naturally or use controlled cooling to ensure stable material properties.

6. Fixed-Length Cutting: Cut the H-beam steel into fixed lengths according to customer requirements.

7. Inspection: Conduct quality inspections on the finished product, including dimensions, shape, and mechanical properties.

8. Packaging and Transportation: Package the qualified products and arrange for transportation.

Process Characteristics：

1. High Production Efficiency

   The rolling process adopts a continuous production method, featuring rapid and highly efficient production capabilities, enabling the large-scale manufacture of H-beam steel with uniform specifications. Modern hot-rolling production lines can achieve an output of dozens of tons per hour, making them perfectly suited for large-scale industrialized H-beam steel production needs. Equipped with advanced rolling equipment and high-efficiency production lines, we are able to provide you with sufficient high-quality rolled H-beam steel in a short period of time, meeting your large-scale project requirements and ensuring the smooth progress of your engineering projects.

2. Stable Product Quality

   Since the rolling process is carried out on highly automated rolling mills and the rolling parameters can be precisely controlled, rolled H-beam steel has significant advantages such as high dimensional accuracy, uniform internal structure, and stable performance. The quality variation is relatively small, making it well-suited for engineering fields with extremely high demands for H-beam steel quality, such as large bridge construction and heavy machinery manufacturing. By choosing our rolled H-beam steel products, you will receive consistently high-quality materials, laying a solid foundation for the quality of your projects.

3. Large Equipment Investment

   However, the rolling process requires large-scale, high-precision rolling mills, as well as supporting equipment such as heating furnaces and cooling systems, resulting in substantial equipment investment. Moreover, the maintenance costs for the equipment are also relatively high. Additionally, the rolling process demands considerable space for production, requiring a large area to accommodate the equipment and carry out production operations. Despite this, we have invested heavily in resources for the rolling process, continuously optimizing equipment and production processes to provide you with the highest quality and most stable rolled H-beam steel products.

Quality Control

Whether H steel is manufactured using welding or rolling processes, strict quality control is implemented throughout the entire production process. During the raw material procurement stage, it is essential to rigorously inspect key indicators such as the chemical composition and mechanical properties of the steel to ensure that the materials used in production are fully compliant with quality standards. During the production process, real-time monitoring is carried out for each step. For example, in the welding process, special attention is given to weld seam quality, while in the rolling process, dimensional accuracy is closely controlled.

The final product inspection phase is particularly critical. In addition to meticulous checks on dimensional tolerances and surface quality of the H-beam steel, comprehensive tests must also be conducted on its mechanical properties, such as tensile strength and bending performance. Only H-beam steel products that strictly meet national standards or specific customer requirements across all metrics are allowed to enter the market.

TIANJIN MUCHANG always prioritize quality, ensuring strict control at every stage from the source to the end product. Our commitment is to deliver the most reliable H-beam steel products to you.

Application Scenarios

• Welded H-beam steel, due to its unique flexibility, is often used in projects with special requirements for H-beam specifications and smaller production volumes. Examples include small-scale building renovations and the fabrication of frames for specific machinery equipment.

  
  

• Rolled H-beam steel, leveraging its high production efficiency and stable product quality, is widely applied in fields with large demand for H-beams and stringent quality requirements, such as large-scale building structures, bridge engineering, and heavy machinery manufacturing.

  
  

  For instance, in the construction of high-rise office building frameworks, rolled H-beam steel is extensively used to ensure the stability and safety of the buildings. In the construction of large cross-sea bridges, rolled H-beam steel serves as the primary load-bearing structural material, providing robust support for the long-term reliable operation of the bridges.

The welding and rolling processes each have their advantages and disadvantages in the field of H beam steel manufacturing, collectively meeting the diverse demands of different engineering sectors for H shape steel. With continuous technological advancements, these two processes are also being constantly optimized, and in the future, they will undoubtedly bring even higher quality and efficiency to the production of H beam metal.
