The climate is turning highly unpredictable, and you must factor this when designing metal homes. This is the view of experts who work in Metro Steel Fabrication and have constructed hundreds of metal structures in and around Queensland. Hurricanes and tornadoes can wreak havoc with building structures as evident from the massive destructions reported across the world, but the story of steel buildings is slightly different because of its better capability to withstand damage and destruction. You must think about ways of keeping steel structures intact during nature’s fury and minimize damages. The action starts by selecting the best metal for buildings.
Steel is the best material
Steel is the strongest material for structures that conform to the latest building codes which are quite stringent. Besides strength, there is another reason for choosing steel as a building material that can withstand natural disasters. Steel is a green material that does away with the need for relying on less sustainable products that stretches the construction time. Steel producing methods have improved significantly to reduce emissions and use less water that adds the green quality to the metal. Using pre-fabricated steel structures speeds up construction that reduces emissions from construction equipment and saves labour. A well-insulated steel building is highly energy efficient and reduces the use of heating and cooling equipment by almost 50%.
To make the steel building rock solid even when the earth shakes during earthquakes, you must consult a geotechnical engineer to determine the susceptibility of the building by testing the soil conditions. This is more important if the building lies in an earthquake sensitive zone. The information is useful for the foundation engineer who factors it into the foundation design to ensure that even the worst tremors have little effect on the building structure.
The roof system
The biggest threat to steel buildings during hurricanes and tornadoes is roof uplift meaning the possibility of the roof flying away. Taking care of this aspect in the design of the building and roof is important. To design a roof that does not fly off, the designer must create a steel roof system with suitable fasteners and secondary framing for reinforcing the overhangs of the roof panels and the corners. Installing high impact doors and windows can keep the damage in check.
During floods, the metal frame and panels of the building are least affected and hence experiences least damage. Although the steel used for building construction comes with a protective coating that makes it corrosion resistant, water damages to the insulation and flooring will still happen. You must replace the damages quickly, but the steel structure remains more or less intact.
Steel has excellent fire-retardant qualities and during a wildfire sparks that reach the structure will not create a fire inside the building. Using minimal roof overhang prevents channeling of hot air, and together with the use of fire-resistant materials in the balconies and decks, the chances of fire spreading across the building is almost non-existent.
Steel gives enough options to create structural designs that remain unaffected by natural calamities.
