1 Scope

China's national standard for fully locked coil cables used in building structures. A fully locked coil rope has an outer layer of Z-shaped wires that interlock with each other, forming a smooth, almost solid cylindrical surface rather than the helical grooves of an ordinary stranded rope. That construction gives it three properties that structural use requires: a higher metallic cross-section for its diameter and therefore a higher modulus, so the structure deflects less; a sealed surface that keeps water out and protects the core, which is what allows a service life measured in decades on an exposed structure; and a form that mates cleanly with the sockets at its ends. It is the cable of stadium roofs, cable-stayed facades, footbridges and tensile structures, where the cable is visible, is expected to last the life of the building, and cannot be replaced without dismantling what it holds up.

This document stipulates the classification, code and marking, ordering content, materials and technical requirements of sealing ropes with a cable body diameter of 20mm~200mm: requirements, inspection methods, inspection rules, packaging, marking and quality certificates: This document is applicable to sealing cables for various building structures such as sports venues, exhibition venues, transportation hubs, commercial centers, and material storage (hereinafter Referred to as "sealing cord"): Sealing cables used in bridges and other areas may be implemented with reference to this document: This document does not apply to sealing ropes made of stainless steel:
