Ten years.
1. Material aging: As time goes by, the material of the ten-year anchor cable will gradually age, resulting in a reduction in its strength and toughness, which will make the anchor cable more susceptible to damage or breakage during the recycling process. .
2. Corrosion: If the anchor cable is exposed to a humid or corrosive environment for a long time, its surface will corrode. This corrosion will weaken the structural integrity of the anchor cable, making it unable to withstand the tensile force during the recycling process.
