Tianrui Steel Co., Ltd — Est. 1998 · Tianjin, China
Built for the
Structures That
Can’t Fail.
From suspension bridges to high-speed rail corridors, Tianrui’s prestressed steel products carry the loads that define modern infrastructure — with 25+ years of precision behind every strand.
Who We Are
Prestressed Steel, Engineered to Global Standards
Tianrui Steel Co., Ltd. was established in 1998 as a professional prestressed steel products enterprise dedicated to research, production, and global sales. From a 10,000 m² facility in Tianjin, we manufacture PC strand, PC wire, and a full suite of anchorage accessories that meet — and routinely exceed — the world’s most demanding construction specifications.
Our products carry international certifications across ASTM A416, GB/T5224, BS5896, JIS3536, AS/NZS4672, EN10138, and more. That breadth of compliance reflects a single conviction: when a bridge deck or railway viaduct depends on your wire, there is no room for approximation.
Today, Tianrui supplies contractors, engineers, and project developers across Asia, the Middle East, Europe, and beyond — backed by a stable supply chain, customized service capabilities, and a quality inspection system that runs from raw wire rod to finished coil.

Product Portfolio
Five Product Families.
One Source You Can Trust.
Every product in the Tianrui range is engineered as part of a complete prestressing system — so components work in harmony rather than just meeting individual specs in isolation.
Technological Process
From Raw Rod to Ready-to-Install Strand — Under One Roof
Tianrui’s vertically integrated manufacturing process gives engineers full traceability at every production stage, from surface treatment of premium high-carbon wire rod through final custom packaging.
Laboratory & QC
Test It Before It Holds Up a Bridge
Tianrui’s in-house laboratory is equipped with advanced mechanical testing instruments operated by a dedicated technical team. Every product batch is tested against the same international standards the project specification demands — no shortcuts.
We provide customers with complete, objective test reports covering every critical performance dimension of the supplied product, giving procurement and engineering teams the documentation they need for project sign-off.
