-Primary advantages
With the interstices of the seven wires filled with epoxy to minimize migration of corrosive media, either by capillary action or other hydrostatic force.
During the continuous pinhole detection process, no more than 2 pinholes are detected every 100 feet [30 meters].
The seven steel wires are filled with epoxy resin, which not only tightly integrates and binds the steel wires into a whole, but also forms a friction-reducing layer between the wires, reducing friction and dislocation between the wires under load, preventing the occurrence of fretting wear fatigue and improving fatigue resistance. In addition, the tensile strength of filled epoxy steel strands is increased by 3-4% compared to single-wire epoxy coated steel strands.
-Why should I buy this Epoxy Coated PC Strand ?
Epoxy Coated PC Strand has very good chemical resistance ,excellent abrasion resistance.
Solve the problem of ordinary prestressed steel strand failure due to corrosion stress, achieved long-term effective and durable anti-corrosion effect, and greatly improved the service life of buildings.
-What makes this product different to other factory's Epoxy Coated PC Strand?
We provide quality guarantee.
-Where can our Epoxy Coated PC Strand be used?
Epoxy Coated PC Strand, as a new type of prestressed material, has been widely used in bridge engineering in China due to its excellent anti-corrosion performance, involving various cable structure fields such as cable-stayed cables, external cables, internal cables, suspension cables, tie cables, geotechnical anchor cables, and anchor prestressed cables.
