The main differences between bright and galvanized wire ropes in terms of line contact lie in their surface treatment processes and corrosion resistance:
Surface Treatment
Bright wire ropes have no coating on their surface; they are only formed by cold drawing and require rust-preventative lubricating grease after twisting.
Galvanized wire ropes use electroplating or hot-dip galvanizing to coat the wire surface with zinc, forming a cathodic protection that effectively isolates the wire from air contact.
Corrosion Resistance
Bright wire ropes are prone to oxidation and rust with prolonged use and require regular maintenance (such as oil immersion), but they are relatively inexpensive.
The zinc coating significantly improves corrosion resistance, making it more stable in humid or corrosive environments and extending its service life.
Applicable Scenarios
Bright wire ropes are often used in light-load, low-corrosion environments (such as general lifting and traction), with low maintenance costs.
Galvanized wire ropes are more suitable for heavy-load, high-corrosion scenarios (such as marine engineering and chemical equipment), with longer maintenance cycles.
