Spiral ribbed PC wire, also called spiral PC wire and spiral ribbed PC steel wire, is one of the traditional products of PC wire. Compared with the plain PC wire, its surface is not smooth but spiral. Commonly, there are 3 - 6 consecutive spiral ribs on the surface. The advantage is that spiral ribs can strengthen the combination between wire and concrete, thus increasing the performance of the PC construction structure and extending its life. What's more, it is widely used in PC telegraph poles, PC hollow slabs, and PC water pipes, etc.
