Through electrolytic galvanizing, a uniform and dense zinc layer is finally formed on the surface of the steel, but the mechanical properties of the material are still maintained. Electrogalvanized steel is usually sold in coil or sheet form. EG coil is a kind of material that can be cut, slitted and profiled for other purposes.\u00a0The steel grade of galvanized steel consists of base metal grade, galvanized (E), galvanized layer type and weight. The electro-galvanized products based on SPCC, SPCD, SPCE, SPCF and SPCG are named SECC, SECD, SECE, SECF and SECG respectively.<\/p>\n
The production process of aluminum zinc plating is as follows:<\/b><\/strong> Scope of Application<\/b><\/strong><\/p>\n Construction industry: such as roof, internal and external wall panels, sound insulation walls, pipes, garages, etc. Galvalume steel coil is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. So it is also known as cold galvanized steel.<\/p>","protected":false},"featured_media":6854,"template":"","meta":{"_seopress_robots_primary_cat":"","_seopress_titles_title":"%%post_title%%","_seopress_titles_desc":"%%post_excerpt%%","_seopress_robots_index":"","site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[123],"product_tag":[],"class_list":{"0":"post-6851","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-galvalume-steel-coil","7":"desktop-align-left","8":"tablet-align-left","9":"mobile-align-left","10":"ast-product-gallery-layout-horizontal-slider","11":"ast-product-gallery-with-no-image","12":"ast-product-tabs-layout-accordion","14":"first","15":"instock","16":"featured","17":"shipping-taxable","18":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/www.gangmingsteel.com\/zh\/wp-json\/wp\/v2\/product\/6851","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.gangmingsteel.com\/zh\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.gangmingsteel.com\/zh\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.gangmingsteel.com\/zh\/wp-json\/wp\/v2\/media\/6854"}],"wp:attachment":[{"href":"https:\/\/www.gangmingsteel.com\/zh\/wp-json\/wp\/v2\/media?parent=6851"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.gangmingsteel.com\/zh\/wp-json\/wp\/v2\/product_brand?post=6851"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.gangmingsteel.com\/zh\/wp-json\/wp\/v2\/product_cat?post=6851"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.gangmingsteel.com\/zh\/wp-json\/wp\/v2\/product_tag?post=6851"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}

\nHeat Reflection<\/b><\/strong>
\nPeople use it as a thermal insulation material, and its thermal reflectivity is up to twice that of galvanized steel.
\nHeat Resistance<\/b><\/strong>
\nGalvanized steel coil has good heat resistance and can withstand high temperatures above 300\u00b0C, which is very similar to the oxidation resistance of aluminized steel at high temperatures. Commonly used in chimney tubes, ovens, illuminators, fluorescent lampshades, etc.
\nCorrosion Resistance<\/b><\/strong>
\nThe key to the corrosion resistance of aluminized zinc steel coil is the protective performance of aluminum. Once the zinc is worn, the aluminum forms a dense layer of aluminum oxide, preventing further internal corrosion.
\nEconomy<\/b><\/strong>
\nThe density of 55% AL-Zn is smaller than that of Zn. Therefore, when the coating weight and thickness are the same, the area of the aluminum-zinc plated steel sheet is 3% larger than that of the galvanized steel sheet.
\nEasy to Paint<\/b><\/strong>
\nThe coating material on the aluminized zinc steel plate has excellent adhesion, and can be directly coated with tar on advertising boards and common plates without pretreatment such as weathering.<\/p>\n![\"\"](\"http:\/\/demo.gangmingsteel.com\/wp-content\/uploads\/2025\/12\/WPS\u56fe\u72471-66.png\")
