· ​ASTM A882 & ISO 14655 Compliance: Manufactured strictly to meet international mechanical, geometric, and coating continuity specifications for epoxy-coated prestressing steel.
· ​Superior Chemical & Moisture Shield: The continuous fusion-bonded epoxy layer forms an impenetrable barrier against chlorides, de-icing salts, acids, and aggressive groundwater attack.
· ​High-Tensile Structural Core: Built upon premium 1860 MPa low-relaxation 7-wire steel strands, delivering uncompromising ultimate breaking load (MBL) reliability for heavy-duty spans.
· ​Enhanced Coating Adhesion & Flexibility: Engineered with superior bond strength and impact resistance, ensuring the coating remains intact during handling, stressing, and structural grouting.
​Engineered for heavy-load-bearing structures exposed to severe corrosive environments:
· ​Bridge & Transportation Infrastructure: Highway and railway bridge decks, segmental box girders, and pier structures subjected to de-icing salts or marine air.
· ​Marine & Coastal Engineering: Offshore platforms, port wharfs, piers, and cross-sea bridge tie-downs.
· ​Heavy Geotechnical Works: Permanent high-capacity ground anchors, rock slopes, and dam foundation stabilization in corrosive strata.
​Q: Do these epoxy-coated strands comply with ASTM A882 and ISO 14655?
A: Yes. Our epoxy-coated PC strands are produced and tested in strict accordance with ASTM A882 and ISO 14655, ensuring full acceptance by global engineering consultants and bridge authorities.
​Q: Does the epoxy coating affect the bonding with concrete or grout?
A: While providing a protective barrier, 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 design codes.
​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.
