Product Overview

This product series includes AS/NZS 4671 Australian‑New‑Zealand standard rebar(300N, 500N) and BS 4449 British standard rebar(Grade460, Grade500).

300N is low‑yield grade for light‑load concrete components; 500N is widely‑adopted high‑strength deformed rebar for Australia and New‑Zealand building & infrastructure. BS4449 Grade460 and Grade500 are reinforcing bar for UK construction projects, Grade500 is dominant 500‑MPa class rebar for British civil engineering.

Hot‑rolled ribbed deformed surface provides reliable anchorage bonding inside concrete. Diameter range 6‑50mm. Standard factory length 9m /12m, custom‑cut length from 3‑18m. Black hot‑rolled surface or epoxy‑coated anti‑corrosion option for coastal construction.
