Corrosion Resistant PC Steel Strand with Epoxy Coating

Epoxy‑coated pc steel strand combines the high strength and low‑relaxation characteristics of plain pc strands with a factory‑applied epoxy barrier that preserves bond to concrete while delivering superior corrosion resistance—making it ideal for long‑lived, exposed, or chloride‑rich prestressed concrete structures. This coating provides a durable barrier against moisture, chlorides, and other corrosive agents, while still allowing the strand to bond to the surrounding grout or concrete after tensioning.

Executive standard for filled epoxy coated steel strand: GB/T21073-2007, JB/T737-2009, ASTM A882/A882M, JG/T387.2012, ISO14655:1999

Why Epoxy Coated PC Strand

• Steel Vulnerability: Bare steel reacts with oxygen and water to form rust, which reduces cross‑sectional area and prestress force over time.
• Prestress Loss: Corrosion accelerates relaxation and can lead to cracking or spalling of the concrete cover.
• Maintenance Costs: Corroded tendons are costly to repair or replace, often requiring traffic closures or extensive remediation.

 Typical Applications

• Bridge Decks & Girders: Exposure to de‑icing salts demands robust corrosion protection while maintaining bonded prestress.
• Parking Structures: Epoxy‑coated strands in precast planks or cast‑in‑place slabs resist vehicle‑borne chlorides.
• Marine & Coastal Projects: Pier decks, wharves, and seawalls where salt spray and tidal immersion occur.
• Architectural Slabs: Exposed post‑tensioned floors or facades that require both protection and a bonded system.
