PC Spiral Rib Wire
Spiral rib wire is invented by Silvery Dragon, representing China’s advanced R&D achievements; it services in China and dedicates to world. The product is characteristic of 3 to 6 spiral ribs through spiral deforming drawing on the surface of wire, increasing the bond ability with concrete, thus improving the overall performance of pre-stressed concrete products and increasing the service life. Silvery Dragon holds the advanced product technology of uniform spiral drawing, internal stress relief and anti-corrosion which meets Germany, USA, France and other international anti-corrosion requirements.
Spiral rib wire is produced by the selected high quality carbon wire rod and refined by strict surface treatment, multi-times drawing and stabilization processing automatic production line. The products range from φ3.8 to 12.0mm in various specifications and different strength levels for customers’ choice. It is especially suitable for the production of railway sleeper, electrical pole, roof board, beam body, etc.
When the spiral rib wire was introduced to the international markets firstly, there was no specification for this kind of wire among all the international standards. Normally, the technical specifications as for the tensile strength, yield strength, corrosion, relaxation confirmed to standards recognized by the customers; and the wire surface shape confirmed to Chinese standard GB/T5223. Now more and more foreign customers adopt directly GB/T5223.
“Based on domestic market and expand overseas business” is our development strategy for OEM China China ASTM A648 Cold Drawn Smooth PC Wire for Prestressed Concrete Pipe, Our items are regularly supplied to lots of Groups and lots of Factories. Meanwhile, our products are sold to the USA, Italy, Singapore, Malaysia, Russia, Poland, plus the Middle East.
OEM China China Steel Wire, PC Wire, The working experience in the field has helped us forged a strong relations with customers and partners both in domestic and international market. For years, our solutions have been exported to more than 15 countries in the world and have been widely used by customers.
