These treatments help increase bolt life, enhancing quality perception and user experience. <\/p>\n<p>In many industries, such as aerospace, automotive, construction, and energy, protective coatings play a key role.<\/p>\n<p>Below, you can find the coatings available for our customers:<\/p>\n<ul>\n<li><strong>Burnishing <\/strong>also called bronzing or metallochroming is the dark surface coloring of a metal practiced by various methods with the purpose of providing protection against oxidation as well as improving its appearance.<\/li>\n<li><strong>Phosphating <\/strong>is a chemical process by which the surface of a metal material is altered, creating phosphate crystals for the purpose of improving corrosion resistance and aiding paint adhesion; it is the universally adopted paint preparation treatment in the automotive industry, as it is essential to achieve the very high corrosion resistance characteristics required of bodies.<\/li>\n<li><strong>Geomet\u00ae<\/strong> is a water-based coating containing zinc and aluminum in lamellar form, capable of withstanding very high temperatures and giving very high protection to metallic materials from environmental corrosion.<\/li>\n<li><strong>Electrolytic Galvanizing<\/strong> is a coating, with different chrome plating, of zinc applied to metal primarily as protection against galvanic corrosion.<\/li>\n<li><strong>Hot dip galvanizing<\/strong> is done by immersing steel products in a bath of molten zinc held at an average temperature of 450 \u00b0C which results in the steel being coated with a thin, tough layer of zinc. It is considered one of the most effective and durable protections <\/li>\n<li><strong>Zinc-Nickel <\/strong>is an innovative electrolytic process based on a ferrous-based deposition of a 12-15% zinc-nickel alloy with natural semi-gloss gray coloring with the possibility of black passivation. Enormously more protective than conventional commercial electrolytic galvanizing. <\/li>\n<\/ul>\n<p>For more information: \u201c<a href=\"https:\/\/www.fastenerandfixing.com\/manufacturing-technology\/the-importance-of-reliability-and-transparency-in-coating\/\">The importance of reliability and transparency in coating.<\/a>\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In the world of bolting, product quality is a priority, [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":1028,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[34],"tags":[],"class_list":["post-1295","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.1 -
