There are two main anti-corrosion coating in prestressed steel fields, metal protective cover and non-metallic protective cover, DAXIONG has successfully developed a non-metallic protective layer of epoxy resin coating and the metal protective layer of the electric galvanized.

Through the method of epoxy coating, DAXIONG give up a traditional methods, which usually spray quartz sand on steel wire surface to increase friction. This new process enhanced the bondability.

DAXIONG possess a self-developed epoxy coating production lines, enhance the physical and chemical performance of Epoxy strand, the equipment and production process were reached the leading level of the world.
Organic coating epoxy resin has many advantages, suah as good anti-corrosion performance, easy operation and Environmentally friendly, etc. For this reason, this product has widely use on global market.

Till now, the epoxy-coated PC Strand technics of Overlay Item and Fill-in Intem are proven.
According to some experts from Chinese epoxy resin industry association, epoxy filler can play a effectively role in anti-corrosion. Epoxy material has effective ability to anti-acid, alkali and salt. Our technicists are working to improve this kind of product, make its anti-corrosion effect better.

Product's advantages:
1)Epoxy coated with strong adhesion to steel
2)Epoxy coated has good chemical stability
