Bridge System
Anchorage systems for post-tensioning
Highway Bridge & Infrastructure
Prestressed steel strand, bridge anchorage systems, and precision rolled threaded steel engineered for post-tensioned bridge decks, cable-stayed and suspension bridge structures, and long-span highway infrastructure.
01 — Industry Challenge
The Problem With Under-Specified Bridge Materials
Highway bridges and long-span infrastructure carry decades of heavy, continuous traffic loading, exposure to weather and de-icing salts, and — in the case of cable-stayed and suspension structures — enormous tensile loads concentrated through a small number of anchorage points. A strand or anchorage system that underperforms on relaxation or anchorage efficiency doesn't just reduce service life; it directly threatens structural safety and can trigger costly load restrictions or emergency retrofits.
For bridge engineers and EPC contractors sourcing prestressing materials, the real risk isn't the published tensile strength on a datasheet — it's whether the anchorage system holds efficiency under sustained load, whether every strand in a multi-strand tendon performs consistently, and whether the supplier can document compliance against the specific standard named in the tender.
02 — Our Solution
Anchorage and Strand Systems Engineered for Long-Span Bridges
Yuanxian supplies Bridge System anchorage components as the core solution for post-tensioned bridge decks, cable-stayed pylon anchorages, and suspension bridge main cable terminations — selected because reliable anchorage efficiency is the single point of failure risk in long-span tensile structures. Paired with our Prestressed Steel Strand, including 1x7 and compacted strand configurations, the system delivers the tensile capacity and low relaxation performance required for tendons that stay in service for 100+ year design lives.
For bridge deck reinforcement, expansion joints, and tie-rod applications, our Precision Rolled Threaded Steel provides a threaded bar solution that simplifies coupling and anchorage compared to standard deformed bar, particularly useful in segmental and continuous box girder construction where post-tensioning ducts must align precisely across segments.

04 — Why Our Product vs. Generic Strand
Built for Long-Span Bridges, Not Just General Construction
| Requirement | Yuanxian Bridge-Grade System | Generic Prestressed Strand |
|---|---|---|
| Anchorage efficiency for high-load tendons | Engineered anchorage system, tested | Strand only, anchorage not matched |
| Relaxation control for long-term prestress retention | Verified ≤ 2.5%, batch-tested | Often unverified per batch |
| Multi-standard compliance for export tenders | GB/T5224, EN10138, ASTM, JIS, BS5896 | Typically single-standard only |
| Corrosion protection for coastal / marine crossings | Galvanized & epoxy-coated strand available | Limited or unavailable |
05 — Standards & Certifications
Compliance for Global Bridge Procurement
Our bridge-grade prestressed strand and anchorage components are manufactured in accordance with recognized international and national standards, selected according to destination market, bridge design code, and project specification:
GB/T5224 EN 10138 ASTM A416 / A910 BS 5896
We support mill test certificates and documentation required for bridge design review and procurement tender processes.

09 — FAQ
Frequently Asked Questions
What type of strand is used for cable-stayed and suspension bridges?
Cable-stayed and suspension bridges typically require high tensile, low relaxation strand paired with an engineered anchorage system, since anchorage efficiency — not just strand strength — determines overall tendon performance.
What's the difference between your Bridge System and standard prestressed strand alone?
Bridge System refers to the complete anchorage and post-tensioning components engineered to work with our prestressed strand, ensuring the anchorage itself doesn't become the weak point in a high-load tendon assembly.
Can you supply materials according to a specific bridge design standard for our tender?
Yes, we manufacture and supply strand and anchorage components in accordance with multiple standards including GB/T5224, EN 10138, ASTM A416/A910, and BS 5896. Contact us with your project specification for confirmation.
Do you provide corrosion-resistant strand for coastal or marine bridge crossings?
Yes, galvanized PC strand and epoxy-coated strand options are available for bridges in coastal, marine, or corrosive environments.
What documentation do you provide for bridge project procurement?
We provide mill test certificates, product specifications, and can support additional testing documentation required for bridge design review and procurement tender processes upon request.
