Why Steel is the Preferred Material in Building Bridges

Steel bridgeBridges connect two places usually separated by a body of water or any obstacle that may impede land transportation. In the U.S., such magnificent structures have contributed to the economy by literally “bridging the gap” of product shipments to and from different places.

And some became landmarks or tourist attractions. Advancements in the areas of science, technology and engineering made it possible to use various materials in building bridges, and one of those materials is steel.

The longest and popular bridges in the US are made of steel

About one-third of the over 600,000 bridges constructed nationwide have used relatively huge amounts of steel, according to a group of corrosion engineers. The Golden Gate Bridge and other extremely long bridges in the country are of steel, mainly because of its affordability and durability.

The Verrazano-Narrows Bridge in New York is another bridge that had been built mainly of steel. The two towers of the 4,175.8m suspension bridge were made of 26,000 tons of steel.

Steel is mainly used in superstructures because it’s highly durable and yet easy to build and maintained unlike other materials like concrete. Steel sheets providers like Hascall Steel Company continue to help build bridges in the country.

Beyond appearance, steel bridges are environmentally safe

Steel bridges are not only pleasing to the eye, but they are also safe for the environment. Unlike concrete, steel parts of a bridge can be recycled, and make for good use again. In extremely long bridges, steel reduces the need to disturb living things mostly if it will span rivers or seas.

Manufacturers produce steel longer than concrete, and bridges could be maintained easily without interrupting the traffic flow. Most of all, steel bridges have been proven to withstand natural calamities such as hurricanes and earthquakes.

Steel bridges serve a lot of purpose to society. Though you can use various materials in building bridges, steel is the best choice for many builders, and now we know why.
