Galvanized unbonded PC strand is a high-strength steel cable coated with zinc for corrosion resistance and lubricated to allow free movement in concrete structures. As a leading wholesale supplier,TJ Wasungen provides premium-quality galvanized unbonded strand for construction applications worldwide.
Galvanized unbonded PC strand offers superior corrosion protection through its hot-dip zinc coating, extending service life in harsh environments. The unbonded design, achieved via plastic sheathing and grease lubrication, enables individual strand adjustment and replacement without damaging surrounding concrete. It provides high tensile strength (typically 1860 MPa) and low relaxation, ensuring long-term structural integrity and reduced maintenance costs.
Lightweight Flexible Solar Panel Supports
Versatile galvanized and unbonded supports for solar panels, offering customizable dimensions and high load capacity for flexible mounting on irregular surfaces.
This product excels in post-tensioning systems for civil engineering projects. Common uses include prestressed concrete bridges, parking structures, nuclear power plants, and commercial buildings where durability against corrosion is critical. It's ideal for marine environments, seismic zones, and areas with high humidity due to its protective galvanization.
Production begins with high-carbon wire rods drawn to precise diameters, followed by stranding into 1x7 or 1x19 configurations. The strand undergoes stress relieving, stabilization, and hot-dip galvanizing in a zinc bath at 450°C for uniform coating (average 200-400 g/m²). Quality checks include tensile testing, relaxation measurement, and coating thickness verification per ISO 9001 standards, ensuring defect-free delivery.
TJ Wasungen excels as a trusted spare parts wholesale supplier with direct sourcing from certified mills in China and Europe. Enjoy competitive pricing, bulk flexibility, technical consultations, fast worldwide shipping, and custom packaging. Our eco-friendly galvanization and rigorous QA ensure reliable, high-performance parts for your global construction and solar projects.

What is galvanized unbonded PC strand?
It's prestressing steel strand with zinc coating for rust protection and unbonded lubrication for free slippage in ducts.
How does it differ from bonded strand?
Unbonded allows post-installation tensioning adjustments; bonded grout fills voids for composite action.
What are typical minimum order quantities?
1 ton for standard sizes; negotiable for custom specs.
Is it suitable for seismic applications?
Yes, its flexibility and high ductility make it ideal for earthquake-resistant designs.
Lead time for delivery?
2-4 weeks from order confirmation, depending on volume and destination.
