FRP vs Metal Electrical Enclosures: The Real 25-Year Cost Comparison

Quick Answer FRP and metal enclosures don’t have a universal winner. The deciding variable is site corrosivity under ISO 12944. Inland, dry, low-pollution sites are well served by coated galvanised steel at lower capital cost. Coastal and heavy-industrial sites see composite (FRP/SMC) pull ahead decisively on 25-year cost, because it removes the corrosion mechanism rather […]
