Let’s get started and learn more about these interesting homes.
What Do We Mean by Steel Frame Houses?
Steel frame houses, as the name suggests, are types of buildings where the main structural framework is constructed using steel. This structure forms a ‘skeleton,’ which can then be filled in with various materials to create walls, floors, and ceilings.
The steel frame of the house provides the foundation for the design and shape of the building, and it is responsible for maintaining the structural integrity of the house.
The use of steel as a primary building material offers significant strength, flexibility, and durability. Steel frames are composed of columns, beams, and other structural elements made of steel, which are all connected together to form a rigid frame.
This type of construction is also known as ‘light gauge steel construction’ when the steel thickness is very small, often used in residential buildings.
In steel frame houses, there are generally two types of frames. The first one is the “Hot-rolled steel frame,” which uses steel I-beams and other wide flanges, and it is mostly used for large buildings.
The second one is the “Light gauge steel frame,” which uses thin steel sheets that are bent into C-sections or Z-sections, and it is used for smaller buildings or residential houses.
It’s important to note that while the steel frame provides the core structure of the house, a variety of finishes are available for the interior and exterior of the building, with options including but not limited to brick, wood, or vinyl siding for the exterior and drywall for interior walls, thus offering aesthetic versatility to homeowners.
Brief History and Evolution of Steel Frame Construction
