Prestress Steel Wire (3–12mm, 1570–1860 MPa) – Complete Technical Guide (2026)

Introduction: Why Prestress Steel Wire Quality Defines Structural Safety Prestress steel wire is the core load-bearing reinforcement in modern concrete structures. From concrete poles and bridge girders to PCCP pipelines and precast slabs, the long-term safety of a structure depends on one critical factor: the consistency and reliability of the prestressing wire embedded inside the concrete. As a professional prestress steel wire manufacturer, Ruibaolong supplies high-performance PC wire from 3mm to 12mm, engineered for: High tensile strength Low relaxation performance Stable and predictable bonding behavior

Cut-to-Length Spiral Ribbed Wire with Tapered Ends(e.g., 4.0mm - 9.0mm)

Maximize your budget with this ready-to-use inventory batch. These spiral ribbed wire bars are pre-straightened, cut to length, and feature precision tapered (bullet-nose) ends for easy insertion. Sold as "Aged Stock" (surface oxidation present) offering full mechanical strength at a clearance price. Ideal for concrete pins, ground stakes, and formwork.

OEM Custom Spiral Ribbed PC Wire (Special Rib Patterns & Mechanical Properties)

Precision straightened bars cut to exact lengths. Eliminates on-site processing for precast factories. Available in all standard diameters.

Pre-Straightened & Cut-to-Length Spiral Ribbed PC Wire Bars (1m - 12m)

Precision straightened bars cut to exact lengths. Eliminates on-site processing for precast factories. Available in all standard diameters.

Large Diameter Spiral Ribbed PC Wire (9.0mm - 12.0mm) for Heavy Infrastructure

The Heavy Lifters. Standard GB/T 5223 specifications in large diameters (9.0mm – 12.0mm). Engineered for massive prestressed girders and high-capacity piles.

Spiral Ribbed PC Wire 3mm 4mm 5mm 6mm for Hollow Core Slabs & Lintels

Perfect for Hollow Core Slabs. 3mm-6mm Spiral Wire with superior anchorage length. Reduces bond slip in short precast elements like lintels.

High Bond Spiral Ribbed PC Wire 7.0mm 9.0mm 10.0mm for PHC Piles & Poles

Best for Centrifugal Spinning. Our spiral rib pattern ensures maximum concrete adhesion for Spun Concrete Poles and PHC Piles. No slippage.

Spiral Ribbed PC Steel Wire for Railway Sleepers (4.8–7.0 mm)

Designed for Railway Safety. High bonding spiral ribs provide 40% better concrete grip than plain wire. Perfect for high-speed rail sleepers and track slabs.

10mm - 13.8mm Extra Large Diameter Steel Wire for Deep Sea Suction Hoses

Rare 10mm-13.8mm High Carbon Steel Wire. SWRH82B grade ensures superior rigidity for heavy-duty suction hose reinforcement.

6.0mm - 9.5mm Plain Round Wire for Dredging Hose Reinforcement Custom Sizes

Heavy duty helix reinforcement wire for sand suction and dredging rubber hoses. High collapse resistance against vacuum pressure. Includes special sizes 6.3mm and 7.5mm.

3.0mm - 5.5mm High Carbon Spring Steel Wire for Mattress and Flexible Hoses

High ductility SWRH82B wire engineered for mattress springs and small industrial hoses. Features excellent fatigue resistance and smooth surface for automated coiling. Available in 3.5mm 4.0mm and 5.0mm.

Prestressed smooth round steel wire

Prestressed smooth round steel wire is a high-strength steel wire with a smooth surface and no ribs. It has good ductility and a stable elastic modulus. This product is widely used in rubber hose winding,

Spiral Ribbed PC Wire - Prestressed Concrete Steel Wire

Ruibaolong Spiral ribbed PC Wire (also known as Prestressed Concrete Steel Wire) features a helical pattern that significantly enhances bonding force with concrete. Unlike standard plain wire, our spiral ribbed surface provides superior anchorage, making it the ideal choice for railway sleepers, pipe piles, and precast beams. We offer high-tensile, low-relaxation wire compliant with ASTM A648, BS 5896, and GB/T 5223 standards.

High-Strength PC Bar (7.1mm-12.6mm)

Prestressed concrete steel bar, abbreviated as PC steel bar, is a type of steel used in prestressed concrete structures. By applying prestress before concrete pouring, it enables the concrete structure to have better

Cold drawn steel wire

Cold-drawn steel wire is a high-strength steel wire made from carbon steel coils at room temperature through processes such as drawing and straightening. It has good mechanical properties and dimensional
