HRB400E is a hot-rolled ribbed steel bar defined in the Chinese standard GB/T 1499.2, characterized by a yield strength of 400 MPa and enhanced seismic performance (Grade E).

Key Details:

  • Standard: GB/T 1499.2 (China).
  • Type: Hot-rolled ribbed/deformed steel bar.
  • Yield Strength: 400 MPa (minimum).
  • Seismic Grade: “E” designation ensures ductility and low yield-to-tensile ratio for earthquake-resistant applications.

This specification is widely used in construction for reinforced concrete structures requiring both strength and earthquake resilience.
