Spiral
SpiralSpiral coils, also known as coiled spiral steel bars, are an important category of hot-rolled ribbed steel bars. They are named for their coiled form. Their core characteristic is the evenly distributed longitudinal and transverse ribs on the surface, combining flexibility with high strength. They are an indispensable core material in the construction engineering field, often referred to as the "flexible force" in building structures. Together with straight threaded steel bars and smooth coils, they form the core system of construction wire materials, but they have clear distinctions in form, specifications, and applications, and are widely used in various civil engineering projects such as housing, bridges, municipal works, and water conservancy projects.- SpiralSpiral coils, also known as coiled spiral steel bars, are an important category of hot-rolled ribbed steel bars.
