2. Core Engineering Advantages

· â€‹Superior Chemical & Moisture Shield: The continuous fusion-bonded epoxy layer forms an impenetrable barrier against chlorides, de-icing salts, acids, and aggressive groundwater attack.

· â€‹Heavy-Duty Load-Bearing Capacity: The 140.0 mm² cross-section and 260.7 kN minimum breaking load deliver the robust tensile strength required for massive bridge spans and structural tie-downs.

· â€‹Enhanced Coating Adhesion & Flexibility: Engineered with superior bond strength and impact resistance, ensuring the protective resin shield remains intact during handling, installation, and grouting operations.

· â€‹Full Metallurgical & Protective Traceability: Manufactured under stringent ISO 9001 protocols. Each commercial shipment includes a comprehensive Mill Test Certificate (MTC) verifying tensile strength, elongation, and coating continuity.

​3. Industrial & Infrastructure Applications

​Engineered for heavy-load-bearing structures exposed to severe corrosive environments:

· â€‹Bridge & Transportation Infrastructure: Highway and railway bridge decks, segmental box girders, pier caps, and stay cables subjected to marine air or de-icing chemicals.

· â€‹Marine & Coastal Engineering: Offshore platforms, port wharfs, piers, and cross-sea bridge foundation tie-downs.

· â€‹Heavy Geotechnical Works: Permanent high-capacity ground anchors, rock slopes, and dam stabilization in aggressive groundwater strata.

​4. Frequently Asked Questions (FAQ)

​Q: Do these epoxy-coated strands comply with international standards?

A: Yes. Our 15.2mm epoxy-coated PC strands are produced and tested in strict accordance with ASTM A882, ISO 14655, and ASTM A416, ensuring full acceptance by global engineering consultants and bridge authorities.

​Q: Does the epoxy coating affect the structural bonding with grout?

A: The specialized surface profile and coating formulations are engineered to maintain sufficient mechanical or structural interlock with cementitious grout or concrete as specified by project engineering designs.

​Q: What is the standard export packaging and transport safety?

A: Coils are carefully wrapped with heavy-duty padding and protective materials, secured with high-tensile steel strapping, and palletized to prevent any impact or abrasion to the epoxy layer during international containerized transit.
