The coating itself is made up of approximately <strong data-start=\"774\" data-end=\"820\">55% aluminum, 43.4% zinc, and 1.6% silicon<\/strong>. This alloy structure combines the <strong data-start=\"856\" data-end=\"890\">barrier protection of aluminum<\/strong> with the <strong data-start=\"900\" data-end=\"934\">sacrificial protection of zinc<\/strong>.<\/p>\n<p data-start=\"937\" data-end=\"1285\">It also gives the material a distinctive appearance.
