      Advantages

      1. Strict JIS Certification, Meeting Japanese Market Access Requirements
      All products pass JIS standard certification, with strict control over harmful elements such as sulfur and phosphorus. They meet the mandatory environmental and quality requirements for Japanese construction and bridge projects, and can be directly used for Japanese local infrastructure projects and imported project tenders.

      2. Full Coverage of Series, Precise Matching of Scenarios
      General Series: Wide Flange  and H Series, suitable for general scenarios such as building beams/columns, bridge main beams, and mechanical equipment frames.
      Extra Large Series: Hyper Beam/Mega Hyper Beam, with unified web/flange height, suitable for super high-rise buildings, large-span venues, and heavy-duty equipment foundations.
      HP Series: H-Beam Pile, Thickened Web Design, meeting high load-bearing requirements for foundation reinforcement and wharf piling.

      3. Stable Performance, Adapting to Japanese Severe Working Conditions
      Small Fluctuation in Material Mechanical Properties: SS400 has excellent weldability, SM490YB stands out in seismic toughness, and SN Series are fully compatible with building structure design codes.
      High Dimensional Accuracy: Strict control of web/flange thickness tolerance to ensure splicing accuracy and structural stability, reducing on-site processing loss.

      4. Customization Services, Catering to Japanese Project Needs
      Support material customization, dimension customization, and surface treatment customization to meet the personalized needs of Japanese high-end residences, precision machinery, new energy wind power and other segmented projects.
