Not every project needs coating, sheathing, or surface treatment. Sometimes, what you need is clean steel, predictable tension, and direct performance. That’s exactly where pc strand plain fits.
At Tianjin Wasungen Metal Products Co., Ltd., we manufacture plain prestressing strand for projects that rely on controlled bonding, accurate stressing, and standard prestressing systems. This type of strand has a smooth surface with no coating, making it easy to anchor, stress, and bond directly with concrete.
We supply plain strands to precast yards, bridge contractors, infrastructure projects, and distributors who want a reliable base material without added layers. As a dedicated pc strand plain manufacturer, we focus on wire quality, strand geometry, and mechanical stability. The result is steel that behaves the same every time you stress it, pour it, and load it.
Plain strand isn’t basic, it’s precise. It gives engineers direct control over how force moves into concrete.
Here’s why many projects still choose plain prestressing strand:
Smooth steel surface – direct contact with concrete
Strong mechanical bond – natural bonding during curing
Accurate stressing response – no coating friction
High tensile strength steel – supports design loads
Seven-wire strand structure – stable force distribution
Simple anchoring – works with standard prestressing systems
Lower material cost – no added coating process
Easy inspection – steel condition visible before use
Many engineers specify a plain prestressed strand when environmental exposure is controlled and bonding performance is the priority.
We produce a full range of prestressing strand types so buyers can source everything from one supplier. Each type serves a different structural purpose.
Plain strand is often used as the foundation option, while coated or unbonded strands are selected for special conditions.
Available subcategories and products include:
Plain 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 12.7mm
Indented PC strand 12.7mm
Indented PC strand 15.2mm
Unbonded PC strand 12.7mm
Low relaxation PC strand 12.7mm
If your design doesn’t require corrosion protection or movement control, plain strand often makes the most sense.
Here’s how plain prestressing strand is typically used, in simple terms:
The strand is placed inside molds or ducts
Tension is applied using stressing equipment
Concrete is poured and cured around the steel
The strand bonds directly with the concrete
Load transfers evenly into the structure
This method is common in precast beams, girders, sleepers, and piles where bonding strength and load control matter.
We keep the process focused and controlled.
High-carbon steel wire is drawn and cleaned
Wires are twisted into seven-wire strands
Heat treatment stabilizes strength and elongation
Diameter and geometry are checked
Tensile and relaxation tests are performed
Finished coils are labeled and export packed
Every batch is traceable, so quality stays consistent across shipments.

Plain PC strand is used in bonded prestressing systems where direct steel-to-concrete bonding is required, such as precast beams, sleepers, and piles.
It can be used outdoors, but corrosion protection should be considered if exposure to moisture or chemicals is expected.
Plain strand has a smooth surface, while an indented strand has surface marks to increase bonding friction with concrete.
Yes. Without coating or sheathing, material cost is lower, making it suitable for controlled environments.
Yes. We regularly ship to South America and Central Asia with full export documentation.
Yes. Each shipment includes mill test reports and inspection documents.
