A Steel Structure Townhouse is a steel-structured residence with a steel structure as its main body. Its primary components include steel beams, steel columns, floor slabs, wall frames, etc. EIHE Steel Structure (EHSS) is a seasoned manufacturer in the steel structure industry. Since our establishment in 2005, we have provided our steel residential buildings to numerous clients.
A Steel Structure Townhouse is a high-density steel-structured residential building characterized by its steel structure and shared gable walls. The main steel structure consists of steel sections, steel plates, light steel keels and other steel materials, featuring light weight, excellent seismic performance and fast construction. The steel residences produced by our factory combine the strength of steel structures with the practicality of civil buildings.

Core advantages of adopting steel structure
1. High matching between steel structure and architectural requirements:
Steel Structure Townhouse requires high-density, low-cost residential buildings. Our steel structure offers excellent formability and economic advantages compared with traditional concrete buildings.
2. Space utilization efficiency:
The steel structure wall is only 180mm thick and can achieve column-free space. The usable area of each bedroom can be increased by 7–8% compared with traditional structures.
3. Fast construction speed:
This is the biggest and most obvious advantage of steel structure. Factory prefabrication plus on-site assembly and highly coordinated manufacturing greatly shorten the construction period.
4. Excellent structural performance:
The strength, formability and recyclability of steel make it highly competitive. Steel structure provides significant improvements over traditional structures in seismic resistance, wind resistance, sound insulation and thermal insulation.
