Q355ND is a normalized high-strength structural steel plate designed for applications requiring enhanced low-temperature toughness and stable mechanical performance. Manufactured according to GB/T 1591, Q355ND offers a minimum yield strength of 355 MPa and impact testing requirements at -20°C.

Compared with Q355NB and Q355NC, Q355ND is widely selected for more demanding engineering projects where safety, toughness, and long-term reliability are important considerations.

CEHE STEEL supplies Q355ND steel plates for heavy engineering, wind power structures, bridges, and large fabrication projects.
