Light Steel Villa Steel Structure 

Core Material: Mainly hot-dip galvanized cold-formed thin-walled steel (Q235/Q345 low-carbon steel). The galvanized layer (180-275g/㎡) on the surface prevents rust, with a service life of over 50 years. C/U/Z-section steel is commonly used, and square tubes/channel steel are used for key joints.

1. Auxiliary Components: Include connectors such as self-tapping screws, M8-M12 bolts and angle brackets, as well as supporting parts like X-shaped/diagonal braces (resisting horizontal loads) and tie rods (preventing purlin deformation).

2. Structure & Force-Bearing: Adopts a "frame-brace system", divided into three parts: walls (bearing vertical + horizontal loads, no load-bearing wall restrictions), floors (bearing the weight of furniture/personnel), and roofs (bearing self-weight/rain/snow, with a drainage slope of ≥5°). Its advantages are light weight (only 1/3-1/5 the weight of brick-concrete structures) and high strength (load-bearing capacity of 200-300kg/㎡), capable of resisting magnitude 8 earthquakes and level 12 typhoons.

3. Construction & Advantages: Follows the process of "factory prefabrication (BIM design, accuracy ±1mm) + on-site assembly". A 100㎡ villa takes about 30-60 days to complete. It is more environmentally friendly (steel recovery rate over 90%) and has more flexible space compared with brick-concrete structures.
