　　Steel-framed houses refer to structures built using steel materials. Due to their light weight and simple, convenient construction process, they are widely used in large factories, stadiums, super high-rise buildings, and other architectural fields. Below are the pros and cons of steel-framed houses:

　　I. Pros and Cons of Steel-framed Houses

　　1.Pros of Steel-framed Houses

　　(1) High Reliability

　　The internal structure of steel is uniform and close to isotropic homogeneity, possessing excellent impact and dynamic load-bearing capacity, as well as superior seismic performance. In practical applications, steel-framed houses exhibit very high reliability.

　　(2) Convenient Installation

　　Steel structures have high strength and elastic modulus. Compared to concrete and wood, steel has a lower ratio of density to yield strength. Under the same loading conditions, steel structural members have smaller cross-sections and lighter weights, facilitating transportation and installation.

　　(3) Good Heat Resistance

　　When the temperature is below 150°C, the properties of steel do not change much, making it suitable for use in hot workshops. However, when the surface of a steel structure is exposed to heat radiation exceeding 150°C, thermal insulation boards are required for protection.

　　(4) Environmentally Friendly

　　The steel used in steel-framed houses can be 100% recycled, enabling circular utilization. Additionally, during construction and demolition, they cause minimal environmental pollution. Therefore, they align well with residential industrialization and sustainable development requirements.

　　2.Cons of Steel-framed Houses

　　(1) Higher Cost

　　The cost of steel-framed houses is higher than that of traditional brick-and-mortar or reinforced concrete houses. This is because steel-framed houses require more new materials, including thermal insulation materials.

　　(2) Substantial Demands

　　Steel-framed houses consist of steel skeletons with lightweight wall and roof materials. The load-bearing capacity, wind resistance, safety, and service life are still unknowns to many people. Therefore, many people still prefer traditional structural houses. The standardization and typification of steel-framed houses are temporarily unable to meet consumers' personalized residential needs.

　　(3) Susceptible to Radiation

　　Steel structures must undergo hot-dip galvanizing treatment to maximize corrosion prevention. In wet and corrosive environments, steel structures are prone to rust.
