Product Features
Structural Strength Balance: Consistent strand diameter and uniform twisting angle provide stable force distribution in pulling and twisting scenarios, ideal for frequent bending applications
Strong Corrosion Resistance: Galvanized coating isolates steel from air and moisture, extending service life 3-5 times longer than smooth steel wire rope in harsh environments
Moderate Flexibility: Smaller bending radius than 7x19 structure with stronger torsional resistance than 1x7 single strand rope, balancing operational ease and structural stability
Outstanding Cost-Effectiveness: Mature production technology and high raw material utilization provide 40%-60% cost reduction compared to stainless steel wire rope for small to medium load scenarios
