Armazenamento de chapas de a\u00e7o estrutural resistentes ao desgaste JFE EH 400:<\/span><\/strong>
Ao armazenar, evite dobrar ou torcer a chapa de a\u00e7o. Rachaduras podem causar corros\u00e3o. Para evitar a corros\u00e3o por pite e a ferrugem decorrentes disso, utilize um pano imperme\u00e1vel. Para remover a umidade do interior do pano imperme\u00e1vel, ventile-o com frequ\u00eancia.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
