Under normal conditions, the service life of channel steel can range from 15 - 50 years. If it is properly maintained and has appropriate surface treatment, such as hot - dip galvanizing, it can last longer. In a relatively dry and non - corrosive environment, channel steel without significant mechanical damage can maintain its performance for a long time. However, in harsh environments with high humidity, Keemiline korrosioon või sagedased mehaanilised mõjud lühendatakse selle kasutusaega . regulaarne ülevaatus ja hooldus võib aidata pikendada selle kasutusaega .
