Steel is a high-strength material comprised of carbon and iron. This metal alloy has several key properties that differentiate it from other types of metal materials, such as:
- High melting point at or above 2500 degrees F.
- An average density of around 7.85kg/m-3, in which this value is a widely accepted standard for various types of steel used in structural engineering.
- Easy deformation with increased shape memory, depending on the alloy.
Steel comes in different grades, with each offering varying elasticity, hardness, ductility, and strength based on the kind of treatment applied during fabrication. Below, learn about the key role steel plays in bridge construction and how it can enhance the overall durability, longevity, and sustainability of various projects.
Why Use Steel for Bridge Construction?
The following are some of the main advantages that make steel a preferred material choice for bridge construction projects:
Superior Strength
Steel structure bridges frequently use this material for its high strength-to-weight ratio. Steel bridges can span long distances and resist physical impacts or disturbances, making them a go-to choice for areas prone to extreme conditions or weather events. Additionally, steel components can withstand heavier loads without contributing large amounts of weight to the overall structure. As a result, bridges benefit from lower construction expenses and increased sustainability in their installation and transportation.
High Longevity and Durability
Steel also provides optimal durability, which is critical for building long-lasting structures. Bridges that utilize these materials can hold up better under exposure to heavy traffic, seasonal changes, and other anticipated conditions. With regular maintenance, they can last for decades following initial construction, making them more cost-effective compared to structures constructed with less reliable materials.
Innovative Designs
Steel’s versatility and weldability allow engineers to develop bridge designs that are both visually appealing and innovative. For example, the material’s superior malleability makes it suitable for forming nearly any shape, leading to structures that complement the surrounding architecture and landscape while providing the necessary support.
Sustainability Matters
Environmental impact is an increasingly critical consideration in the construction of bridges. This need is another reason why steel is such a popular material in these applications; its durability decreases overall impact and reduces the need for raw materials, making for a more environmentally friendly solution compared to other materials. Further, steel bridges can be constructed with recycled steel and can also be adapted over time, ensuring they serve future generations.
Local Impact
Local communities benefit from the use of steel structure bridges in a number of ways. For example, steel bridge construction creates job openings in fabrication, manufacturing, and construction. Subsequently, communities can see more economic growth when erecting these structures. The final construction also facilitates ease of transportation, smoother traffic, and increased accessibility to improve the lives of the general populace.
