If your project needs stronger bonding between steel and concrete, pc strand indented is built for that job. At Tianjin Wasungen Metal Products Co., Ltd., we manufacture indented prestressing strands designed to grip concrete better and reduce slippage under load.
We supply indented strands for bridges, precast beams, sleepers, piles, and structural elements where load transfer matters. The small surface indentations increase friction with concrete, helping the strand lock in place once tension is released. That means better force distribution and more stable structures.
Our buyers include contractors, precast factories, EPC firms, and distributors who need consistent quality across large volumes. As an experienced indented pc strand manufacturer, we focus on uniform indentation depth, stable tensile strength, and export-ready packaging. You get steel that behaves the same on every pour, not surprises halfway through the project.
Indented strands solve a simple problem: smooth steel doesn’t always grip concrete well enough. That’s where surface indentation helps.
Here’s what makes our indented strands practical on site:
Improved bond strength – indentations increase friction between steel and concrete
Better load transfer – tension moves evenly into the concrete
Reduced slippage risk – helps maintain design performance
High tensile steel core – meets prestressing load needs
Seven-wire strand structure – balanced stress distribution
Stable elongation values – predictable stressing behavior
Compatible with standard anchors – no special hardware needed
Reliable batch consistency – same performance across shipments
Many engineers specify prestressed indented strands when bonding performance is critical. It’s a practical choice for precast yards and infrastructure projects where long-term stability matters more than surface finish.
We supply several prestressing strand types to match different construction needs. Each type is produced under controlled conditions to keep quality steady across orders.
For bonding-focused applications, indented strands are often preferred over plain strands. Alongside this, we also offer coated and unbonded options for projects with corrosion or movement requirements.
Available subcategories and products include:
Indented PC strand 12.7mm
Indented PC strand 15.2mm
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
Unbonded PC strand 12.7mm
Low Relaxation PC Strand

Here’s how indented prestressing strand is used, explained simply:
The strand is placed inside molds or ducts before concrete is poured
Tension is applied using stressing equipment
Concrete is poured and cured around the strand
Tension is released, transferring force to the concrete
Indentations grip the concrete, improving bond and stability
This process helps reduce cracking and improves structural performance, especially in precast beams, sleepers, and piles where bonding strength is important.
We control production from raw steel to final packing.
High-carbon steel wire is drawn and cleaned
Wires are twisted into seven-wire strands
Controlled indentation is applied along the surface
Heat treatment stabilizes mechanical properties
Tensile strength and elongation are tested
Coils are labeled and packed for export
Each batch is traceable, so performance stays consistent from order to order.

Indented PC strand is used where strong bonding between steel and concrete is required, such as precast beams, sleepers, piles, and bridge components.
The surface indentations increase friction with concrete, helping reduce slippage and improve load transfer after tensioning.
For bonded systems, yes. Indented strands provide better grip, while plain strands are often used where bonding is less critical.
Yes. We supply 12.7mm and 15.2mm indented strands based on project needs.
Yes. We regularly ship to both regions and handle export packing and documentation.
Yes. Mill test reports and inspection documents are included with every shipment.
