SS Wire Rope
What are SS Wire Rope?
SS Wire Rope, or Stainless Steel Wire Rope, is a flexible, high-strength assembly of metal wires twisted into strands, used extensively in load-bearing, hoisting, marine, and structural applications. Known for its superior corrosion resistance, tensile durability, and fatigue strength, SS wire rope performs exceptionally well in harsh, corrosive, or outdoor environments.
Asiad Steel Industries is a leading manufacturer and exporter of premium-grade stainless steel wire ropes, available in multiple strand patterns such as 6×19, 7×7, and 7×19, and in grades like SS 304, SS 316, and SS 316L.
