PRODUCT INTRODUCTION
The performance of the mono-filament sprayed epoxy steel strand meets the stringent standards of GB/T25823-2010. Mono-filament Coated Epoxy-Coated Prestressed Steel Strand.
The performance of the filled epoxy steel strand complies with the rigorous standards 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. 3007. It is crafted from high-grade lipid acid-proof carp soap, thickened with deeply refined mineral oil, enhanced with antioxidants, anti-rust agents, and corrosion inhibitors. This formulation significantly boosts adhesion, water resistance, rust resistance, and overall anti-corrosion performance.
Currently, two international standards govern epoxy-coated steel strands: ASTM. A 882/A 882M-02a and ISO 14655:1999 (E). These standards delineate two product types: epoxy-coated filled strands and epoxy-coated steel strands. While ASTM A 882/A882M-02a outlines specifics for epoxy-coated filled steel strands, ISO 14655:1999 (E), derived from ASTM A 882/A882M-96, maintains regulations for both product types. ASTM A 882/A882M-96 retains the standards for epoxy-coated strand products, encompassing both types.
Epoxy-coated steel strands boast exceptional corrosion resistance, leading both standards to impose stringent coating thickness and surface pinhole regulations. ASTM A 882/A 882M-02a specifies a coating thickness ranging from 0.38-1.14mm for epoxy-coated filled strands. ISO 14655:1999 (E) stipulates a thickness of 0.40-0.90mm for epoxy-coated filled steel strands and 0.65-1.15mm for epoxy-coated strands.
Both ASTM A882/A882M-02a and ISO 14655:1999 (E) mandate a flawless, pinhole-free coating along the entire length of the finished epoxy-coated steel strand. Our products meet and exceed these rigorous international standards.
PRODUCT FEATURES
Our epoxy-coated steel strands deliver unparalleled anti-corrosion properties,
1) The gaps between the steel wires are meticulously filled with epoxy resin.
2) The steel strand's surface is enveloped in a robust epoxy resin coating, ensuring a pinhole-free, continuous length.
3) The specialized epoxy resin forms a strong bond with the steel strand's metal matrix, stretching synchronously without cracking during or after tensioning.
PRODUCT APPLICATIONS
As an innovative, high-performance anti-corrosion prestressed material, our epoxy-coated steel strand is extensively utilized in various engineering fields. These include cable-stayed bridges, partial cable-stayed structures, external and internal cables, as well as geotechnical anchorage systems across the United States, Europe, Japan, Australia, and other regions in Europe, America, and the Asia-Pacific.
