La barra HRB400 de 8 mm es una barra de acero deformado de alta resistencia, dise\u00f1ada para proporcionar un refuerzo estructural superior en proyectos de construcci\u00f3n de hormig\u00f3n. Esta barra de 8 mm de di\u00e1metro, ampliamente utilizada en aplicaciones de hormig\u00f3n armado (HF), combina una excepcional resistencia a la tracci\u00f3n con una ductilidad fiable, lo que la convierte en la piedra angular de los proyectos modernos de construcci\u00f3n, infraestructuras e ingenier\u00eda civil. Aunque es distinta de la Q235B (un acero estructural al carbono general), la barra corrugada HRB400 se utiliza a menudo junto con estos materiales en estructuras compuestas, ofreciendo un rendimiento complementario cuando es fundamental una alta capacidad de carga.<\/div>","protected":false},"featured_media":2742,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"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":[32],"product_tag":[],"class_list":["post-3034","product","type-product","status-publish","has-post-thumbnail","product_cat-rebar","desktop-align-left","tablet-align-left","mobile-align-left","first","instock","shipping-taxable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/baosteelmaterials.com\/es\/wp-json\/wp\/v2\/product\/3034","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/baosteelmaterials.com\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/baosteelmaterials.com\/es\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/baosteelmaterials.com\/es\/wp-json\/wp\/v2\/comments?post=3034"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/baosteelmaterials.com\/es\/wp-json\/wp\/v2\/media\/2742"}],"wp:attachment":[{"href":"https:\/\/baosteelmaterials.com\/es\/wp-json\/wp\/v2\/media?parent=3034"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/baosteelmaterials.com\/es\/wp-json\/wp\/v2\/product_brand?post=3034"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/baosteelmaterials.com\/es\/wp-json\/wp\/v2\/product_cat?post=3034"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/baosteelmaterials.com\/es\/wp-json\/wp\/v2\/product_tag?post=3034"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
