prestressed wire

In producing high performance prestressed hollow slab, cold rolled rib steel and cold drawing grade ⅱ, grade ⅳ steel were replaced by 1270~ 1570 MPa mid-high strength spiral wire as prestressed reinforcement for hollow slab.

以强度为1270～1570MPa的中高强螺旋肋钢丝代换冷轧带肋钢筋及冷拉Ⅱ级、Ⅳ级钢筋作短向和长向圆孔板的预应力配筋，试生产高效预应力构件已获得成功。
