Values such as wire rope tensile strength and steel cable breaking strength vary not only by diameter, but also by strand count, wire grade, and core type. For example, a 1\/4 wire rope strength rating differs significantly from a 3\/8 wire rope strength, even when both are made from the same material, simply due to cross-sectional area and construction.<\/p>\n\n\n\n\n\n\n    <meta charset=\"UTF-8\">\n    <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\">\n    <style>\n        .wire-rope-container {\n
