◉ Product Introduction
Rebar in coils, also known as coil rod deformed steel bar, is manufactured from hot-rolled low-carbon steel and micro-alloyed steel. It features stable mechanical properties, uniform dimensions, and strong bonding strength with concrete. Compared with straight rebar, it saves material waste, improves construction efficiency, and is widely used in high-speed railways, highways, bridges, precast components, and various reinforced concrete projects.
