Textile-Covered Steel Strand for Concrete Prestressing from China
High-tensile steel strand, 12.7mm diameter, coated with polyethylene textile material for corrosion protection, specifically designed for prestressing post-tensioned concrete structures like bridges and buildings. It falls under HTS 7312.10.3010 due to its stranded steel construction, non-metallic covering, and explicit use in prestressing concrete. The textile covering enhances bonding and durability in concrete applications.

Import Tips
• Verify strand tensile strength and coating composition via mill test certificates to confirm prestressing classification; ensure non-metallic covering meets Chapter 73 wire definitions under 16mm dimension
• Common pitfall: misclassifying as bare strand (7312.10.3005) without documentation of textile cover
