El dise\u00f1o con m\u00faltiples pliegues crea una estructura r\u00edgida, similar a una caja, que proporciona una rigidez excepcional y resistencia a las fuerzas de flexi\u00f3n.<\/li>\n<li>Capacidad de carga: Ofrece una resistencia y una capacidad de carga excepcionales, que superan a las de muchos perfiles est\u00e1ndar. Esto lo convierte en la opci\u00f3n ideal para zonas de alto impacto, como autopistas de alta velocidad, curvas cerradas y tramos propensos a accidentes.<\/li>\n<li>Rigidez estructural: El dise\u00f1o garantiza que el poste se mantenga estable bajo cargas pesadas, evitando movimientos excesivos o el colapso en caso de impacto, lo que permite mantener la integridad de la barrera de seguridad.<\/li>\n<\/ul>\n<p>\u2705 Gran flexibilidad y absorci\u00f3n de energ\u00eda<\/p>\n<ul>\n<li>Deformaci\u00f3n controlada: Su dise\u00f1o exclusivo permite una deformaci\u00f3n controlada durante las colisiones. A diferencia de los postes r\u00edgidos, que pueden romperse o deformarse de forma catastr\u00f3fica, el perfil Sigma est\u00e1 dise\u00f1ado para plegarse y deformarse de manera predecible.<\/li>\n<li>Disipaci\u00f3n de energ\u00eda: Esta deformaci\u00f3n controlada permite una mejor absorci\u00f3n y distribuci\u00f3n de la energ\u00eda cin\u00e9tica derivada del impacto. El pilar disipa la energ\u00eda del veh\u00edculo de forma gradual, reduciendo las fuerzas m\u00e1ximas que se transmiten al veh\u00edculo y a sus ocupantes.<\/li>\n<li>Mayor seguridad vial: Al absorber la energ\u00eda del impacto y minimizar el rebote de los veh\u00edculos, el SIGMA POST contribuye a reducir la gravedad de los accidentes, a disminuir el riesgo de accidentes secundarios y a mejorar la seguridad vial en general.<\/li>\n<\/ul>\n<p>\u2705 Protecci\u00f3n contra la corrosi\u00f3n<\/p>\n<ul>\n<li>Recubrimiento galvanizado: Acabado con un recubrimiento galvanizado de alta calidad, que ofrece una excelente resistencia al \u00f3xido y a la corrosi\u00f3n.<\/li>\n<li>Resistencia en condiciones exteriores: El recubrimiento protege el poste de factores ambientales como la humedad, los rayos UV y los contaminantes qu\u00edmicos. De este modo, se garantiza que se mantengan la integridad estructural y el aspecto del poste a lo largo de su vida \u00fatil.<\/li>\n<li>Menor mantenimiento: El acabado resistente a la corrosi\u00f3n prolonga considerablemente la vida \u00fatil del poste, lo que reduce al m\u00ednimo la necesidad de mantenimiento, pintura o sustituci\u00f3n, incluso en entornos exteriores adversos.<\/li>\n<\/ul>\n<p><img alt=\"\" decoding=\"async\" class=\"size-full wp-image-7764 aligncenter\" src=\"http:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/9.webp\" width=\"546\" height=\"449\" srcset=\"https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/9.webp 546w, https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/9-300x247.webp 300w, https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/9-15x12.webp 15w\" sizes=\"(max-width: 546px) 100vw, 546px\" \/><\/p>\n<p><strong><b>1<\/b><\/strong><strong><b>.3 Especificaciones t\u00edpicas (normas habituales del sector)<\/b><\/strong><\/p>\n<div class=\"wp-responsive-table\">\n<table>\n<tbody>\n<tr>\n<td><strong><b>Par\u00e1metro<\/b><\/strong><\/td>\n<td><strong><b>Detalles<\/b><\/strong><\/td>\n<\/tr>\n<tr>\n<td>Material<\/td>\n<td>Acero Q235B \/ S235JR (conformado en fr\u00edo y soldado por alta frecuencia)<\/td>\n<\/tr>\n<tr>\n<td>Revestimiento<\/td>\n<td>Galvanizado en caliente o pregalvanizado, espesor de la capa de zinc \u2265 85 \u03bcm<\/td>\n<\/tr>\n<tr>\n<td>Tama\u00f1os de secci\u00f3n<\/td>\n<td>Perfiles Sigma est\u00e1ndar, por ejemplo, 140 \u00d7 60 \u00d7 4 mm, 150 \u00d7 70 \u00d7 4 mm; tambi\u00e9n disponibles a medida<\/td>\n<\/tr>\n<tr>\n<td>Longitud<\/td>\n<td>De 1,5 m a 2,5 m, o seg\u00fan los requisitos de dise\u00f1o del cliente<\/td>\n<\/tr>\n<tr>\n<td>Normas<\/td>\n<td>Cumple con las normas EN 1317, EN 10346 u otras normas regionales de seguridad vial<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p><img alt=\"\" decoding=\"async\" class=\"size-full wp-image-7765 aligncenter\" src=\"http:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/11-1.webp\" width=\"669\" height=\"488\" srcset=\"https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/11-1.webp 669w, https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/11-1-300x219.webp 300w, https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/11-1-16x12.webp 16w, https:\/\/www.shandongruiying.com\/wp-content\/uploads\/2026\/05\/11-1-600x438.webp 600w\" sizes=\"(max-width: 669px) 100vw, 669px\" \/><\/p>\n<p><strong><b>1<\/b><\/strong><strong><b>.4 Aplicaciones clave<\/b><\/strong><\/p>\n<ul>\n<li>Autopistas y autov\u00edas de alta velocidad<\/li>\n<li>Tramos de carretera de alto riesgo (curvas, cruces, pendientes pronunciadas)<\/li>\n<li>Carriles para veh\u00edculos pesados y rutas para camiones<\/li>\n<li>Zonas con un historial de accidentes frecuentes<\/li>\n<li>Proyectos que dan prioridad a un alto nivel de seguridad en caso de colisi\u00f3n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>SIGMA POST (poste de acero con forma de sigma para barreras de seguridad) es un poste de soporte de acero de alta resistencia dise\u00f1ado para sistemas de barreras de seguridad y barreras anticolisi\u00f3n en autopistas.
