The current development of light-steel frame buildings in the United States exhibits the following characteristics:

Market Size and Share
Light-steel frame buildings in the United States have a significant market share in the residential sector, reaching 75% in 2000 and maintaining a high market share. There are 200,000 small steel-framed residential buildings, primarily villas and multi-story residences.

Technical Features
Galvanized cold-formed thin-walled steel sections are used as the load-bearing structure. The center distance between the wall steel frames is generally 400mm or 600mm, with cross-sectional dimensions ranging from 93 to 200mm and steel plate thicknesses ranging from 0.84 to 1.91mm. This structural system is suitable for low-rise two- to three-story residences, offering both earthquake resistance and rapid construction.

Policy and Environmental Protection
California and other regions are promoting the use of light-steel systems through carbon neutrality service policies, viewing it as a key solution to achieving carbon neutrality goals. The recyclable nature of light-steel materials is highly consistent with environmental requirements, resulting in a short construction cycle and high material utilization.

Industry Maturity
The US light steel frame building industry has developed a complete industry chain, achieving standardization and modularization from design to construction, with nearly 100% component commonality. The application of BIM technology further enhances its competitiveness.
