PRODUCT INTRODUCTION
The remarkable performance of our mono-filament sprayed epoxy steel strand adheres strictly to the stringent standards of GB/T25823-2010. Mono-filament Coated Epoxy Coated Prestressed Steel Strand.
Our filled epoxy steel strand meets and exceeds the rigorous specifications of GB/T21073-2007 "Epoxy Coated Seven Wire Prestressed Steel Strand" and JT/T. 737-2009 "Filled Epoxy Coated Steel Strand."
Anti-corrosion grease performance: Complies with JG standard. 3007. This high-grade grease is formulated with lipid acid-proof carp soap, deeply refined mineral oil, and enhanced with antioxidants, anti-rust agents, and other selective additives. This composition significantly improves adhesion, water resistance, rust resistance, and anti-corrosion properties of the grease.
Currently, two notable international standards apply to epoxy-coated steel strands: ASTM A 882/A 882M-02a and ISO 14655:1999 (E). These standards define two types of epoxy-coated steel strands: epoxy-coated filled strands and epoxy-coated strands. The ASTM 2002 version specifically mentions that while epoxy-coated filled steel strands are specified, epoxy-coated steel strands are not recommended; ISO 14655:1999 (E) retains the guidelines for both products based on ASTM. A 882/A882M-96, which includes comprehensive regulations for both product types.
Epoxy-coated steel strands are celebrated for their superior corrosion resistance, hence both standards enforce strict criteria on coating thickness and pinhole presence on the surface. ASTM A 882/A 882M-02a mandates a coating thickness of 0.38 - 1.14mm for epoxy-coated filled strands. ISO 14655:1999 (E) specifies the coating thickness for filled steel strands between 0.40 - 0.90mm, and for epoxy-coated strands between 0.65 - 1.15mm.
Both ASTM A882/A882M-02a and ISO 14655:1999 (E) insist that there must be no pinholes throughout the entire length of the finished epoxy-coated steel strand. Our products adhere impeccably to both these international standards.
PRODUCT FEATURES
Our epoxy-coated steel strands boast unparalleled anti-corrosion properties.
1) The gaps between the steel wires are meticulously filled with epoxy resin.
2) The surface of the steel strand is coated with a sufficiently thick epoxy resin layer, ensuring no pinholes over the entire length.
3) The specialized epoxy resin forms a robust bond with the steel strand’s metal matrix, preventing cracks during and after tensioning.
PRODUCT APPLICATIONS
As an innovative high-performance anti-corrosion prestressed material, our epoxy-coated steel strand finds extensive application in various engineering fields. These include cable-stayed cables, partial cable-stayed cables, external and internal cables (including tie cables), and geotechnical anchorage. Our products are trusted and utilized in the United States, Europe, Japan, Australia, and across numerous other regions in Europe, America, and the Asia-Pacific.
