Muchas barandillas econ\u00f3micas que se comercializan est\u00e1n fabricadas con acero reciclado. Aunque a simple vista parecen similares, su fragilidad, su contenido en impurezas y su rendimiento mec\u00e1nico inestable suelen provocar fallos en los proyectos y riesgos para la seguridad.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Todas nuestras barandillas para exportaci\u00f3n est\u00e1n fabricadas con acero laminado en caliente 100% de primera calidad Q235B \/ Q355B, sin ning\u00fan tipo de material reciclado.<\/p>\n\n\n\n

1. Pureza y resistencia estables<\/h2>\n\n\n\n

El acero reciclado contiene grandes cantidades de impurezas, lo que lo hace fr\u00e1gil y propenso a agrietarse ante un impacto. El acero de primera calidad presenta una estructura interna uniforme, una tenacidad estable y un rendimiento fiable en la absorci\u00f3n de energ\u00eda, y cumple plenamente con las normas de seguridad EN 1317 y AASHTO.<\/p>\n\n\n\n

2. Mejor adherencia del galvanizado<\/h2>\n\n\n\n

El acero reciclado de baja calidad provoca una mala adhesi\u00f3n del zinc, lo que da lugar a descascarillamientos, \u00f3xido blanco y fallos en el recubrimiento durante el transporte mar\u00edtimo. El acero de primera calidad garantiza una adhesi\u00f3n perfecta del galvanizado y un rendimiento anticorrosivo a largo plazo.<\/p>\n\n\n\n

3. Estabilidad dimensional precisa<\/h2>\n\n\n\n

El acero reciclado se deforma y se dobla f\u00e1cilmente tras su fabricaci\u00f3n debido a tensiones internas inestables. El acero de primera calidad garantiza una superficie plana de la viga, un radio est\u00e1ndar y una tolerancia de instalaci\u00f3n precisa.<\/p>\n\n\n\n

Proporcionamos certificados de ensayo de f\u00e1brica (MTC) originales para cada lote. Se acepta una inspecci\u00f3n completa realizada por terceros para proyectos internacionales.<\/p>","protected":false},"excerpt":{"rendered":"
