Aluminum is one of the most sought-after metals in the world. It’s been used in countless home and building designs for over one hundred years. Some of the most recognizable structures also contain this popular metal, including the Empire State Building in NYC and the Lakhta Center in Russia. Here’s why aluminum continues to be a game-changer in the construction industry:
It’s Versatile
Aluminum is very versatile and works well in most construction settings. Builders can use it in most parts of a structure, including as the main support or a decorative feature. It’s ideal for welding, casting, forging, or rolling. Most construction workers agree that metal from an aluminum foundry is easier to work with than other available metals. Aluminum alloys are often the go-to choice for railings, door frames, gutters, and even roofs. Since aluminum weighs less than other options, it’s also more cost-efficient to transport.
It’s Extremely Robust
Aluminum is one of the strongest metals available. It has a strength-to-weight ratio that is higher than most other options. Although lightweight, aluminum can support most construction projects. For example, aluminum alloys are strong enough to hold heavy glass spans, which are a common design element in modern skyscrapers and office buildings.
It’s Airtight
Unlike most other metals out there, aluminum is airtight. Other building materials naturally develop cracks as they age. Not only do these cracks look bad, but they cause unwanted air leakage. On the other hand, aluminum does not crack like steel and wood. Instead, it remains airtight for years. This feature makes it more energy-efficient and can help reduce the heating and cooling costs in large buildings. The metal’s air-tightness also makes it the prime choice for many decorative features, including door and window frames.
It’s Highly Durable
Engineers want to build structures that will stand the test of time. That’s why they often incorporate aluminum. This metal is resistant to corrosion, making it extremely long-lasting. This trait alone reduces maintenance costs over the long run. Aluminum’s durability makes it ideal for all climates. It can withstand hot and cold temperatures and won’t deteriorate in humid or dry environments.
It’s Attractive
The construction industry values aluminum for its attractive appearance. Aluminum alloys are easy to polish and have a smooth, shiny look. It can also change colors. The anodizing process changes the metal’s surface chemistry, and builders can add pigments to create different hues. Designers also enjoy working with this aesthetically pleasing metal. Long before aluminum was used in construction, it was a popular material in decorative applications.
It’s Environmentally Friendly
Many construction companies seek Leadership in Energy and Environmental Design certification for building projects. For a project to qualify, it must meet specific environmental standards. There is a high demand for sustainable building materials, and aluminum tops the list. Aluminum is energy efficient and completely recyclable. This shiny actually reflects heat, reducing energy costs during hotter months. Buildings with a high aluminum content have an overall lower carbon footprint.
Modern Architecture Relies on Aluminum
Nearly every modern building uses aluminum as a structural design element. Without this incredibly versatile metal, downtown skylines full of towering skyscrapers would not exist. Aluminum is perhaps the most robust, durable, and attractive metal available today, and it’s a staple in the construction industry for many good reasons. As modern architecture reaches new heights, the popularity of aluminum will continue to increase.
