How long does expanded metal mesh last?

The service life of expanded metal mesh depends largely on the material and environment. Stainless steel expanded mesh can last 30-50 years or more, even in harsh coastal or industrial environments. Hot-dip galvanized carbon steel typically lasts 20-30 years outdoors, while aluminum offers excellent corrosion resistance with similar longevity. The one-piece construction means there are no welds to fail, which significantly extends its lifespan compared to welded products. With minimal maintenance — occasional cleaning and inspection — expanded metal mesh provides decades of reliable service. This longevity makes it a cost-effective investment for long-term projects.
