Timber! Say Goodbye to Deteriorating Wooden Bridges.
Steel-timber bridges only have a lifespan of ten years, at best, and require routine maintenance and upkeep.
Major flaws with steel-timber bridge designs include:
The heavy design and extreme vulnerability to the elements shortens the lifespan of wooden bridges and requires yearly maintenance upgrades that can be costly and time consuming. Steel-timber structures tend to decay rapidly in the absence of routine maintenance, which will only decrease its already very short lifespan.
Wood is also an organic material that acts as a food source for various insects and animals. The deterioration this causes can only be solved by applying preventive coatings that, unfortunately, can also affect the health of a steel-timber bridge. Since wood is extremely flammable, it’s also necessary that a fire retardant be applied to a steel-timber bridge.
The disadvantages of wood prove it to be more work than it’s worth when it comes to bridge design.
Aluminum can increase the lifespan of a bridge by 30 years while also eliminating the need for yearly maintenance.
Benefits of aluminum bridges include, but are not limited to:
The durable design of an aluminum bridge makes it able to withstand all the elements of nature. This omits the need for expensive, routine maintenance to prevent and fix the rapid deterioration that steel-timber bridges often see.
A light-weight aluminum bridge is half the weight of wood and a third the weight of steel, and its high-strength allows for a larger load bearing capacity. This relieves the effort and time it takes to install and transport the bridge.
Aluminum has a natural protective coating and corrosion resistance that wood does not. Toxic chemical coatings are not required for upkeep on an aluminum bridge, limiting your carbon footprint and making it the sustainable choice for your project.
