La norma anticorrosi\u00f3n para los proyectos de exportaci\u00f3n es mucho m\u00e1s estricta que la aplicable a las carreteras nacionales ordinarias. El recubrimiento est\u00e1ndar de zinc de 550 g\/m\u00b2 solo es adecuado para zonas secas del interior. En el caso de los proyectos de autopistas costeras e insulares, <strong>Recubrimiento de zinc de alto espesor: 1100 g\/m\u00b2 \u2013 1200 g\/m\u00b2<\/strong>&nbsp;es necesario para garantizar una vida \u00fatil de entre 15 y 20 a\u00f1os sin necesidad de mantenimiento.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Las barandillas galvanizadas est\u00e1ndar para exportaci\u00f3n presentan un recubrimiento de zinc uniforme, sin faltas de recubrimiento ni grumos, y un comportamiento estable en las zonas de flexi\u00f3n y punzonado. Algunas f\u00e1bricas utilizan procesos de galvanizado secundario de baja calidad, que, aunque tienen un aspecto similar a simple vista, se oxidan r\u00e1pidamente durante el transporte mar\u00edtimo y no superan la inspecci\u00f3n del proyecto.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Todas nuestras barandillas para exportaci\u00f3n cumplen con la norma internacional ISO 1461.
