Steel Production Process<\/h2>\n
\n

Pressed welded steel grating.<\/strong>\u00a0The cross bar is pressed into the bearing bar by an automatic resistance welding machine.<\/p>\n

Penetration welding grating.<\/strong>\u00a0Pre-drill holes in the bearing bars, usually in the middle. Insert the cross bar, usually a round bar. Weld it into shape.<\/p>\n

Press locked steel grating.<\/strong>\u00a0The pressed locked steel grating is made of bearing bars through processes such as grooving (holes), plug-in cross flat or serrated bars pressing, welding, and finishing.<\/p>\n

Swage locked grating.<\/strong>\u00a0The cross bar is pre-threaded and then clamped into shape using special equipment. Usually used in the production of aluminum gratings.<\/p>\n

Riveted steel grating.<\/strong>\u00a0The connecting bar(cross bar) is bent and fixed with rivets in a direction parallel to the bearing bar.<\/p>\n\n<\/div>\n

      Hot-dip galvanized steel grating, also known as bar grating, is made by arranging load-bearing flat steels and cross bars at specific intervals, welding them into raw panels using high-voltage resistance welding machines, and then processing them into finished products through processes such as cutting, notching, hole punching, and hemming. The welded steel grating is immersed in molten zinc, and a dense zinc layer is formed on its surface through a zinc-iron alloy reaction. This process significantly enhances the corrosion resistance of the steel grating and extends its service life.<\/p>","protected":false},"featured_media":9071,"template":"","meta":{"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":"","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":[45,47],"product_tag":[],"class_list":{"0":"post-9070","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-steel-grating","7":"product_cat-steel-bar-grating","8":"desktop-align-center","9":"tablet-align-center","10":"mobile-align-center","12":"first","13":"instock","14":"featured","15":"shipping-taxable","16":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/www.steelgratingchina.com\/it\/wp-json\/wp\/v2\/product\/9070","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.steelgratingchina.com\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.steelgratingchina.com\/it\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":10,"href":"https:\/\/www.steelgratingchina.com\/it\/wp-json\/wp\/v2\/product\/9070\/revisions"}],"predecessor-version":[{"id":10140,"href":"https:\/\/www.steelgratingchina.com\/it\/wp-json\/wp\/v2\/product\/9070\/revisions\/10140"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.steelgratingchina.com\/it\/wp-json\/wp\/v2\/media\/9071"}],"wp:attachment":[{"href":"https:\/\/www.steelgratingchina.com\/it\/wp-json\/wp\/v2\/media?parent=9070"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.steelgratingchina.com\/it\/wp-json\/wp\/v2\/product_brand?post=9070"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.steelgratingchina.com\/it\/wp-json\/wp\/v2\/product_cat?post=9070"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.steelgratingchina.com\/it\/wp-json\/wp\/v2\/product_tag?post=9070"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
