Choose HRB400, HRB400E, HRB500 or HRB500E Inside This Page
This HRB rebar page does not need separate HRB400 or HRB500 child pages. Buyers usually search and compare HRB grades together. Keep all grade selection, mechanical comparison, RFQ details, packing and document support on one page so the quotation path stays clear.
HRB400 Rebar
You can request HRB400 rebar for common reinforced concrete construction, buildings, infrastructure and distribution supply.
HRB400E Rebar
You can choose HRB400E when the project requires HRB400 strength level with seismic or ductility-related acceptance.
HRB500 Rebar
You can select HRB500 rebar when the project needs higher yield strength than HRB400 and the design documents accept this grade.
HRB500E Rebar
You can request HRB500E when the project needs higher strength plus seismic or ductility-related test requirements.
HRB400, HRB400E, HRB500 and HRB500E Comparison
HRB400 and HRB500 are selected by strength level. E grades are used when the project requires seismic or ductility-related acceptance. Before quotation, confirm whether the buyer only needs a common HRB grade or must match E-grade mechanical control.
| Grade | Reference Yield Strength | Reference Tensile Strength | Reference Elongation | E Grade Control | Best Used When |
|---|---|---|---|---|---|
| HRB400 | ≥ 400 MPa | ≥ 540 MPa | A ≥ 16%, Agt ≥ 7.5% | Not E-grade controlled | General reinforced concrete, building projects, distributors and standard construction supply. |
| HRB400E | ≥ 400 MPa | ≥ 540 MPa | A ≥ 16%, Agt usually controlled higher for E grade | Rm/ReL ≥ 1.25, actual yield / grade yield ≤ 1.30, Agt ≥ 9.0% | Projects requiring HRB400 strength level with seismic or ductility-related acceptance. |
| HRB500 | ≥ 500 MPa | ≥ 630 MPa | A ≥ 15%, Agt ≥ 7.5% | Not E-grade controlled | Higher-strength reinforcement where project design approves HRB500 instead of HRB400. |
| HRB500E | ≥ 500 MPa | ≥ 630 MPa | A ≥ 15%, Agt usually controlled higher for E grade | Rm/ReL ≥ 1.25, actual yield / grade yield ≤ 1.30, Agt ≥ 9.0% | Higher-strength reinforcement with seismic or ductility-related project requirements. |
HRB Rebar Grades Supplied on One Page
HRB buyers normally compare grade, diameter, length, MTC and packing together. Keeping HRB400, HRB400E, HRB500 and HRB500E on one page is better for quotation conversion than splitting each grade into small pages.

Common Questions from HRB Rebar Buyers
Do HRB400, HRB400E, HRB500 and HRB500E need separate pages?
No. For this website structure, they should stay on one HRB rebar page. Buyers usually compare these grades together by strength level, E-grade requirement, diameter, length, MTC and packing.
What information should I send for an HRB rebar quotation?
You should send grade, diameter, length, quantity, bundle weight, standard, MTC requirement, packing requirement and destination country or port.
What diameter range can you supply?
HRB rebar can be supplied from 6.0–50mm diameter. Final availability depends on grade, quantity, length, packing requirement and production schedule.
What is the difference between HRB400 and HRB500?
HRB500 has a higher reference yield strength than HRB400. HRB400 is commonly selected for general reinforced concrete construction, while HRB500 is used when the project design requires and accepts higher-strength reinforcement.
What is the difference between HRB400 and HRB400E?
HRB400E keeps the HRB400 strength level but adds seismic or ductility-related acceptance control, such as strength ratio, yield ratio and Agt requirements.
Can HRB400, HRB400E, HRB500 and HRB500E be quoted together?
Yes. Mixed grade inquiries can be reviewed together, but each grade should have clear diameter, length, quantity, bundle requirement, document requirement and destination details.
Can you provide MTC, heat number and loading photos?
Yes. MTC, heat number, chemical composition, mechanical properties, bend test, re-bend test, packing photos and loading photos can be discussed according to order requirements.
