The zinc layer act as sacrificial anode, corroding first to protect the underlying steel. As a result, galvanized steel is highly corrosion-resistant, making it ideal for outdoor use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Similarly, aluminium is highly corrosion-resistant due to the formation of a thin but dense aluminium oxide layer on its surface. This aluminium oxide layer acts as a barrier to protect the underlying metal from further corrosion. Additionnaly, this oxide layer is self-repairing&nbsp;: if the surface is scratched or damaged, the aluminium oxide layer quickly reforms and prevents corrosion from occurring.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"384\" height=\"287\" src=\"https:\/\/www.nenuphar.com\/wp-content\/uploads\/2026\/09\/image-7.png\" alt=\"\" class=\"wp-image-19857\" srcset=\"https:\/\/www.nenuphar.com\/wp-content\/uploads\/2026\/09\/image-7.png 384w, https:\/\/www.nenuphar.com\/wp-content\/uploads\/2026\/09\/image-7-16x12.png 16w, https:\/\/www.nenuphar.com\/wp-content\/uploads\/2026\/09\/image-7-300x224.png 300w\" sizes=\"auto, (max-width: 384px) 100vw, 384px\" \/><figcaption class=\"wp-element-caption\">Aluminum appearance<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"377\" height=\"283\" src=\"https:\/\/www.nenuphar.com\/wp-content\/uploads\/2026\/09\/image-8.png\" alt=\"\" class=\"wp-image-19858\" srcset=\"https:\/\/www.nenuphar.com\/wp-content\/uploads\/2026\/09\/image-8.png 377w, https:\/\/www.nenuphar.com\/wp-content\/uploads\/2026\/09\/image-8-16x12.png 16w, https:\/\/www.nenuphar.com\/wp-content\/uploads\/2026\/09\/image-8-300x225.png 300w\" sizes=\"auto, (max-width: 377px) 100vw, 377px\" \/><figcaption class=\"wp-element-caption\"> Spangle-free galvanized coil<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"388\" height=\"291\" src=\"https:\/\/www.nenuphar.com\/wp-content\/uploads\/2026\/09\/image-9.png\" alt=\"\" class=\"wp-image-19859\" srcset=\"https:\/\/www.nenuphar.com\/wp-content\/uploads\/2026\/09\/image-9.png 388w, https:\/\/www.nenuphar.com\/wp-content\/uploads\/2026\/09\/image-9-300x225.png 300w, https:\/\/www.nenuphar.com\/wp-content\/uploads\/2026\/09\/image-9-16x12.png 16w\" sizes=\"auto, (max-width: 388px) 100vw, 388px\" \/><figcaption class=\"wp-element-caption\">Spangled galvanized coil<\/figcaption><\/figure>","protected":false},"excerpt":{"rendered":"<p>STEEL&nbsp;: Advantages Disadvantages ALUMINIUM&nbsp;: Advantages Disadvantages Stainless steel is often preferred for fasteners, chainplates, and critical structural components \uf0e0 strenght + corrosion resistance Aluminium is deal for everything that must be lightweight (masts, booms, travellers, blocks, winches) DINGHY TROLLEYS Galvanized steel \u2013 Pros Aluminium \u2013 Pros In summary&nbsp;: Galvanized steel = strenght and durability Aluminium [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"om_disable_all_campaigns":false,"_uag_custom_page_level_css":"","_monsterinsights_skip_tracking":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_post_was_ever_published":false,"_members_access_role":[],"_members_access_error":""},"categories":[1015],"tags":[1055],"class_list":["post-19856","post","type-post","status-publish","format-standard","hentry","category-advices","tag-chariot-en"],"acf":[],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.1.1 - aioseo.com -->\n\t<meta name=\"description\" content=\"STEEL : Advantages Very strong et rigid \uf0e0 high mechanical resistance, ideal for parts that must withstand heavy loads.
