Product Overview
Huaxia-Steel supplies carbon steel rebar and deformed bar — the ribbed reinforcing steel that gives concrete its tensile strength — directly from Chinese rolling mills to construction importers, trading houses, and precast concrete plants worldwide. We supply bars in diameters from 6 mm to 50 mm, in grades from HRB335 to HRB500 and international equivalents, with full GB/T 1499 / ASTM A615 / BS 4449 conformance and EN 10204 2.1 or 3.1 certification.
