Do folding container house roofs have an effective drainage system?

Yes. Folding container house roofs designed by WELLCAMP are equipped with a well-structured and aesthetically optimized drainage system to ensure efficient rainwater management and long-term structural protection. Roof drainage design is an important part of overall building performance, especially for modular and prefabricated structures exposed to varying weather conditions.

• Roof slope and corrugated steel structure

The roof is constructed using arched corrugated steel tiles combined with a slight double-slope design. This structure naturally guides rainwater toward the edges of the long side of the unit. Water is then efficiently collected into the internal gutter system, preventing standing water and reducing long-term roof load stress.

• Sealing at structural joints

Waterproof structural adhesive is applied at all joints between roof tiles and folding container top beams. This treatment ensures full sealing of the roof system, minimizing the risk of leakage at connection points and improving overall weather resistance and durability.

• Integrated drainage system with downpipes

Standard internal downpipes are installed as part of the drainage system. These pipes efficiently channel rainwater collected from both sides of the roof down to ground level, ensuring controlled discharge and preventing water accumulation around the structure.

Through this integrated roof design, WELLCAMP folding container houses achieve reliable drainage performance, enhanced waterproofing, and improved long-term structural stability in different climatic environments.
