If you’re sourcing reliable pc strands for construction or infrastructure work, you’re in the right place. At Tianjin Wasungen Metal Products Co., Ltd., we manufacture and supply prestressing strands built for real job-site conditions, not lab theory. Our focus is simple: strong steel, stable performance, and steady supply for long-term projects.
We produce prestressed concrete strand solutions used in bridges, highways, buildings, rail sleepers, and energy structures. Our strands are made from high-carbon steel wire, twisted into seven-wire configurations that hold tension, resist fatigue, and stay consistent over time. Whether you need corrosion protection, bonding strength, or flexibility for post-tension systems, we’ve got options that fit your drawings and your budget.
Most of our clients are contractors, EPC firms, distributors, and project owners who need a pc strand supplier they can count on. They come back because our material performs the same way on the last shipment as it did on the first. No surprises. No shortcuts. Just steel that does its job.
Choosing the right prestressing material saves you trouble later. Our strands are designed to make your work easier on site and safer over the structure’s life.
Here’s what you get when you buy from us:
Low relaxation performance – reduces long-term tension loss, especially in continuous loads
High tensile strength – handles heavy stress without sudden failure
Seven wire strand structure – balanced load transfer and stable anchoring
Uniform diameter and coating – smooth installation and predictable behavior
Corrosion protection options – epoxy-coated and galvanized variants for harsh environments
Strict dimensional control – fits standard anchors and stressing systems
Factory-direct supply – stable pricing and consistent quality
Export-ready packaging – coils secured for long-distance shipping
Our pc steel strand products work well in both pre-tension and post-tension systems. They’re tested for elongation, breaking force, and relaxation loss before shipment. That means fewer site delays and fewer questions during inspection.
Simply put, you get material that behaves the way engineers expect it to behave.
We offer several strand types to match different structural needs. Each type serves a clear purpose, depending on exposure, bonding needs, and installation method.
Our main products include epoxy-coated strands for corrosion resistance, hot-dipped galvanized strands for outdoor or marine conditions, indented strands for improved bonding, unbonded strands for post-tension slabs, and plain strands for standard prestressing work.
Available subcategories and products include:
Epoxy-Coated PC Strand
Epoxy-coated PC strand 12.7mm
Epoxy-coated PC strand 15.2mm
Epoxy-coated PC strand 15.7mm
Hot-Dipped Galvanized PC Strand
Hot-dipped galvanized PC strand 12.7mm
Indented PC Strand
Indented PC strand 12.7mm
Indented PC strand 15.2mm
Unbonded PC Strand
Unbonded PC strand 12.7mm
Plain PC Strand
Low Relaxation PC Strand
Low relaxation PC strand 12.7mm
Each option is produced under the same quality system, so switching types doesn’t mean changing suppliers or standards.
If you’re not a technical expert, here’s how these strands are used in real life—step by step.
Steel strands are placed inside concrete forms or ducts before pouring
Tension is applied using hydraulic jacks
Concrete is poured and cured around the stressed steel
Tension is released, transferring force into the concrete
The structure gains strength without adding extra weight
You’ll see prestressed steel strand used in:
Bridge girders and decks
Highway flyovers
Railway sleepers
High-rise floor slabs
Precast beams and piles
Solar panel support foundations
The result is longer spans, fewer cracks, and better load control.
We control every step inside our production line.
High-carbon steel wire is drawn and cleaned
Wires are twisted into seven-wire strands under controlled tension
Heat treatment improves mechanical stability
Coating or surface treatment is applied when required
Finished strands are tested for strength, elongation, and relaxation
Coils are labeled, packed, and prepared for export
Each batch is traceable. If there’s a question later, we know exactly where it came from.
Our strands are produced to meet common international standards, including:
ASTM A416 / A416M
EN 10138
GB/T 5224

PC strand is used to strengthen concrete structures by adding controlled tension before or after the concrete sets. This tension helps concrete handle heavy loads, reduces cracking, and improves durability. You’ll often find it in bridges, highways, railway sleepers, floor slabs, beams, piles, and large precast elements where normal steel reinforcement isn’t enough.
Yes, we do. Low relaxation PC strand is designed to keep its tension over time. This makes it a good choice for long-span structures, continuous beams, and projects where load stability matters for many years. It helps reduce maintenance issues caused by tension loss.
Yes. We regularly export PC strand to countries across South America and Central Asia, including Brazil, Chile, Argentina, Kazakhstan, Uzbekistan, and more. Our team handles export packing, documents, and logistics to make overseas delivery smooth and reliable.
Our PC strand products are manufactured according to international standards such as ASTM, EN, and GB. The exact standard can be matched to your project or local code requirements. Test results are checked before shipment to meet those specifications.
Yes. Epoxy-coated PC strand provides extra protection against moisture, salt, and chemical exposure. It’s commonly used in coastal areas, humid climates, industrial zones, and structures exposed to aggressive environments where plain steel may corrode faster.
Yes. Mixed container loading is available. You can combine different diameters, coatings, or strand types in a single order, as long as quantities and packing conditions allow. This helps reduce shipping costs and simplifies sourcing.
Yes. Every shipment comes with mill test reports showing tensile strength, elongation, relaxation performance, and other required values. These certificates help with inspections, approvals, and project documentation.
