What are the advantages of lightweight steel framing compared to traditional framing?

Excellent fire resistance: Lightweight steel framing is made of steel with a melting point of over 1300 ℃. It is a non combustible material that does not ignite or support combustion when exposed to fire. After special fire protection treatment, the fire resistance time can reach 1.5-3 hours. Traditional wooden keel is flammable, and in a fire, it not only burns quickly but also accelerates the spread of the fire; Although gypsum framing has a certain degree of flame retardancy, its fire resistance time is usually not as long as lightweight steel framing, and it is prone to softening and losing support at high temperatures.

Strong moisture and corrosion resistance: Lightweight steel framing can effectively resist erosion from humid environments through surface treatment processes such as hot-dip galvanizing. Even when used in long-term humid southern areas or spaces with heavy water vapor such as kitchens and bathrooms, it is not easy to rust or deform, and its service life can reach more than 50 years. Traditional wood framing is prone to moisture, mold, and decay in humid environments, leading to a decrease in structural strength; Traditional framing of some metal materials, without proper rust prevention treatment, is also prone to rusting and damage, affecting building safety.

Outstanding load-bearing capacity: Lightweight steel framing is made of high-strength steel as raw material, with a tensile strength of 300-500MPa. A single standard U-shaped light steel keel can withstand a vertical load of over 100kg, and can stably support heavy ceiling and partition materials. In contrast, traditional wood framing is prone to fracture due to uneven density and unstable load-bearing capacity of the wood material; Ordinary gypsum framing has weak load-bearing performance and is difficult to meet the support needs of large decorative materials.

Easy and efficient installation: The lightweight steel framing has uniform specifications and a high degree of prefabrication, which does not require complex on-site processing during construction. It can be quickly assembled through matching connectors, greatly reducing the construction period. Data shows that using lightweight steel framing for ceiling projects can shorten construction time by about 40% compared to traditional keel materials.

Environmental sustainability: Steel has extremely high recyclability, and lightweight steel framing can be 100% recycled and reused after disposal, reducing the generation of construction waste. However, traditional wooden keels use a large amount of wood resources, which is not conducive to forest resource protection and difficult to degrade after disposal;
