A home with "heart" of steel is designed to stand the test of time, even in extreme weather climates.
The inherent strength and durability of steel provide structural integrity in all types of environments and conditions - from cyclone and Hurricane regions in the US and Australia to Earthquake and seismic regions in New Zealand and Japan. A steel-framed home can be designed to withstand all that the weather can throw at it.
The walls of each home are its backbone and strength, they are designed to withhold the vertical dead and live loads of the roof and above floors, but they perform equally as well at the same time in securing the holding down of the above floors and roof in the event of severe high winds.
This advantage is often overlooked, but each stud of a steel frame home acts equally in holding up the home as it does holding down the home. Other construction methods create this artificially, adding to the cost and complexity of the construction process.
