At Chengdong Modular House, we know that a truly functional engineering camp needs more than just living quarters and offices — it also demands high-performance production buildings that can stand up to tough site conditions while keeping costs under control.
Traditionally, heavy H-shaped steel structures come with downsides: high self-weight, longer fabrication times, and higher transportation costs over long distances. To solve these pain points, our dedicated R&D team at Chengdong reimagined the traditional portal frame. Through repeated technical upgrades and real-world testing, we developed a lightweight, cold-formed steel structure that’s precision-engineered for modern camp construction. This innovative system is now a trusted solution for large functional buildings like workshops, storerooms, canteens, and more — wherever your project takes you.
The structure is a galvanized structure, which greatly improves the moisture-proof and anti-corrosion performance.
It can be mass-produced mechanically with a short processing cycle; it can realize all-bolt assembly connection, resulting in a short installation period.
The amount of steel used in the structure is low, the self-weight is light, the requirements for the foundation are low, and the disassembled parts can be packed in containers, which greatly saves the container volume.
Product Introduction can not only be used as workshops and warehouses, but the improved product introduction can also be used as large offices and restaurants.
