Built for Long-Term Resilience

Resistant Against Pest and Weather Threats

Finally, steel is an optimal material for people who are worried about pest or weather-related threats.

Termites

Termites infest wood buildings because they are attracted to cellulose, an organic material found in wood that serves as a termite’s primary food source. Steel buildings are made from 100% inorganic material, so they don’t supply the same food as wood buildings do. You don’t have to worry about termites when you choose steel!

Rodents

Large rodents and other pests will also be unlikely to make your steel building their home because there are no cracks or spaces for them to crawl through. There are also fewer places for them to hide. If you’re in an area where you’re regularly battling mice, rats, or other pests, steel is a great choice for you.

Wind

Steel buildings can be manufactured to withstand wind speeds in excess of 180MPH, so they can withstand the vast majority of hurricanes and tornadoes. Whether you’re on the coast or tornado alley, steel can keep you and your valuables safe.

Water

Unlike wood, steel doesn’t absorb water. If it floods, your building will remain undamaged. If you live in a humid area, you won’t have to worry about moisture damaging your structure.

Fire

Steel is fire-resistant and won’t combust in the same way wood does. As a result, steel buildings can impressively resist electrical fires and wildfires.

Earthquakes

Steel is durable, yet lightweight. This means it can bend under pressure rather than snap. When earthquakes occur, steel will absorb the shock from the ground moving below rather than break, providing you with a reliable structure.
Trusted Quality, Coast to Coast

Certified Steel Buildings for Every State

At Atlantic Steel Structures, the integrity of your steel building is important to us. We want your building to be able to endure local weather threats and meet the required building codes. That’s why we’ll work with you and an engineer in your state to make sure your building is manufactured in accordance with state and local building codes.
