H beam section steel structural steel S355JR for supporting

H beam section structural steel S355JR adopts innovative asymmetric rolling technology, and through differentiated web/flange deformation control, the Z-directional performance is improved to Z35 level while maintaining a low yield strength ratio of 0.85. Its intelligent temperature control system achieves precise regulation of cross-sectional temperature difference ≤ 15 ℃.

H section steel S355JR utilizes a 5G+AI quality monitoring platform to detect internal defects in real-time through millimeter wave inspection, with a false detection rate of less than 0.3%. The unique Cr Ni Mo microalloy formula enables an impact energy of over 54J at -40 ℃.

As the core material of the modular support system, it has passed the American standard A992 certification and achieved a 30% increase in span in the seismic support bracket of the data center.
