Product Overview

HRB400, HRB400E, HRB500, HRB500E deformed steel rebar are hot‑rolled ribbed reinforcing bars manufactured complying with GB 1499.2‑2018 Chinese national standard. The “E” suffix stands for seismic‑resistant grade, specially developed for seismic critical construction projects.

These deformed rebar feature transverse ribs on surface to maximize mechanical anchorage with concrete matrix, effectively transfer tensile stress inside reinforced concrete structures. HRB400/HRB400E is widely used for ordinary residential and commercial buildings; higher strength HRB500/HRB500E reduces steel consumption for heavy‑load foundation, bridge and high‑rise construction.

Available diameter covers 6mm‑50mm. Standard factory length 9m and 12m, custom cut‑to‑length from 3‑18 meters upon project demand. We can supply black hot‑rolled finish or epoxy‑coated anti‑corrosion surface treatment. All batches come with official mill test report including heat number, chemical composition and mechanical test records. Widely applied in residential complex, high‑rise building, bridge, highway, dam and infrastructure in global construction tender projects.

FAQs

What is difference between HRB400 and HRB400E steel rebar?

E stands for seismic‑resistant. HRB400E has stricter requirements on yield ratio and toughness, mandatory for high‑rise and earthquake‑prone zone construction. HRB400 is for ordinary non‑seismic projects.

Can you supply epoxy‑coated HRB500E rebar for coastal projects?

Yes, we provide epoxy coating surface treatment for all GB deformed rebar to resist chloride salt corrosion in seaside environment.

What is MOQ for HRB series rebar?

Our minimum order quantity is 5 ton. Mixed‑grade loading is acceptable within one container.

Can you cut rebar to non‑standard special length?

Yes. Standard lengths are 9m and 12m, and customized cutting lengths from 3m to 18m are available according to project requirements.

Which international grade can replace HRB500E for overseas tender?

B500B (EN10080), ASTM A615 Grade60 are common equivalent reference grades, but local project specification shall be followed first.
