data-end=\"1246\">Its production generally involves <strong data-start=\"767\" data-end=\"788\">three core stages<\/strong>: <strong data-start=\"790\" data-end=\"807\">pre-treatment<\/strong>, <strong data-start=\"809\" data-end=\"832\">hot-dip galvanizing<\/strong>, and <strong data-start=\"838\" data-end=\"856\">post-treatment<\/strong>. The corrosion resistance of HDG comes mainly from its <strong data-start=\"912\" data-end=\"941\">dual protection mechanism<\/strong>. One is the <strong data-start=\"954\" data-end=\"976\">barrier protection<\/strong> provided by the zinc coating, which isolates the steel from corrosive media. The other is <strong data-start=\"1067\" data-end=\"1093\">sacrificial protection<\/strong>, in which the zinc corrodes first to protect the base steel. Together, these two mechanisms give HDG a <strong data-start=\"1197\" data-end=\"1245\">long service life even in harsh environments<\/strong>.<\/p>\n<\/div><\/div><\/div><div
