In a rural or semi-rural environment with low pollution and low humidity, a standard structural galvanised coating (45\u201355 microns) will typically provide corrosion protection for 70\u201380 years before first maintenance is required. In an urban or industrial environment with higher pollution levels, service life is typically 40\u201360 years. In a coastal or marine environment (within 1km of the sea), service life reduces to approximately 20\u201330 years. In all cases, galvanised steel significantly outlasts untreated or painted mild steel equivalents \u2014 making it the most cost-effective long-term choice for outdoor structural applications.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The service life of hot-dip galvanised steel depends primarily on [&hellip;]<\/p>\n","protected":false},"author":6,"featured_media":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","format":"standard","meta":{"footnotes":""},"faq_category":[187],"class_list":["post-17139","avada_faq","type-avada_faq","status-publish","format-standard","hentry","faq_category-galvanised-steel-profiles"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>How long will galvanised steel profiles last outdoors?
