Spiral Ribbed PC Wire for Reinforcing Structure

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.

With high bonding force, spiral ribbed PC wire has a wide range of using: prestressed concrete structures, building structures, reinforcing structures, road and bridge structures, etc.
Three pieces of spiral ribbed PC wire with different diameters.
We can supply spiral ribbed PC wire with different diameters from 3.00 mm to 12.00 mm. All can be produced according to your specific requirements.

With consecutive spiral ribs on the surface, spiral ribbed PC wire has a strong bonding force.
Seven layers of spiral ribbed PC wire are tied up with steel baling strips. And each layer is separated with a wooden block.
Compared with plain PC wire, spiral ribbed PC wire can better combine with concrete.
