<strong>Aluminium sheet plate</strong> is being regarded as a new star in bridge building because of its obvious advantages: bright and aesthetic appearance, high corrosion resistance, no maintenance in the entire life cycle, lower construction and maintenance cost, and high recovery rate. Almost all of the aluminum can be recycled, and more than 95% of the recycled aluminum can be obtained with the performance equivalent to the original aluminum, leaving steel far behind in this regard, which is less than 70%. with these superior performances, aluminium is considered to be the most dynamic and vital new material in bridge building.<br></p>

In 2008, a study conducted in Canada fully proved this point. Of the 9 aluminum bridges built between 1946 and 1963, there are still 6 as newly built; the density of <strong>
aluminium plate</strong> products is lower, so the weight of the bridge is lower than that of the steel bridge. The low concrete bridge is conducive to manufacturing, transportation and installation. At the same time, the width of the bridge can be increased, and the supporting members can be reduced and lightened. This is particularly important for the load limitation of the bridge and the repair of historical bridges . Generally, aluminum bridge decks are 70% to 80% lighter than concrete bridge decks and most other metal bridge decks.</p>

Research shows that a steel bridge made of galvanized steel 3.24 meters wide and 28.6 meters long costs 28% to 167% higher than an aluminum bridge after 50 years. The study also shows that the cost of aluminum bridges in 33 years is lower than that of galvanized steel bridges. This is only a comparison of the cost of bridges made of two materials in the general atmospheric environment. The corrosion resistance of
aluminum plate under severe corrosion conditions is higher than that of steel. At this time, the advantages of aluminum bridges will be more prominent. The advantages of aluminum in the construction of floating bridges and movable bridges are self-evident.</p>

Of course, not all
aluminium alloys are suitable as materials in bridge building. <strong>3003
aluminium alloy</strong>, for example, is neither strong nor corrosion resistant enough to shoulder such a responsibility. Only stronger ones like 6061 and 7075 are sufficiently capable to fill the gap.</p>
