Aluminum deck is lighter than concrete 80%, and no need to strengthen the supporting bridge components can provide additional bridge width and capacity. Corrosion resistant aluminum alloy bridge deck without the need of paint and maintenance is very small, and more suitable than steel or concrete to use in addition to the use of the de icing chemicals.
Aluminum is a fast, cost-effective construction.Because it is low temperature toughness, so that aluminum in the cold climate of the ideal roads, bridges and other structures. Aluminum is lighter than steel and concrete, it does not need painting or protective coating, and reduces the maintenance and installation time, thereby reducing the cost of aluminum than other materials have obvious advantages.
Aluminum material is a kind of ideal material, it can increase the width without increasing the load of bridge, and it is a kind of movable bridge, bridge and bridge deck. As the seismic force is proportional to the weight, the aluminum is also an excellent bridge seismic reinforcement. The new aluminum material board system requires the factory to be prefabricated, welded, and has a crush on the deck and the shop is applied to the construction of surface wear speed. Precast aluminum deck panels can be installed faster than other systems, without the need for on-site welding.
Nowadays, aluminum is widely used in commercial parties and residential construction, applied to the window and door frames, exterior cladding, hanging plate, gutters and downspouts, and roof. In many cases, low weight, high strength, and durability of aluminum alloy make the construction contractor attractive.
