What Are the Pitfalls of Container Houses

Container houses may have the following 'pitfalls':

---

I. Quality and Safety Issues

1. Insufficient structural stability: Some non-standard off-brand manufacturers reduce costs by using thin steel frames, with wind resistance ratings of only 6 - 7, far below the national standard requirement of over 8. In coastal areas or under strong wind conditions, problems such as frame deformation and wall cracking are prone to occur, leading to high rework costs.
2. Poor fire resistance: Some products from small manufacturers do not meet the national standard requirement of Class B1 or above for fire resistance. They mostly use flammable materials, with a fire resistance rating of only Class C. In case of a fire, the fire spreads rapidly, causing serious casualties and property damage.
3. Poor fire-resistant performance of the building, prone to collapse: Most container houses use steel structures for support. In a fire, the high temperature in the fire scene causes the exposed steel structures to deform quickly. Ordinary container houses generally lose their load-bearing capacity and collapse within about 10 minutes after a fire breaks out.
4. The core materials of the panels are easily ignited and spread rapidly: Some container houses use flammable materials such as polyurethane and polystyrene to fill the panel cores. These materials have low ignition points and poor flame retardancy. They will immediately burn when exposed to high-temperature sparks, and the honeycomb structure of the materials increases the contact area with air, resulting in intense burning.

II. Usage Experience Issues

1. Low living comfort: The thermal insulation performance of low-end products cannot be guaranteed, and the sound insulation performance may also be poor. Metal materials have good sound transmission effects, requiring additional sound insulation treatment. The internal space is relatively small, with poor ventilation and lighting, and is prone to generating odors due to environmental pollution.
2. Hidden dangers in internal water and electricity pipelines: Most products from small workshops are temporarily wired on site, with exposed wires, posing safety hazards.

III. Cost and After-sales Issues

1. High total life-cycle cost: The installation of non-standard products takes a long time and requires additional professional personnel. The comprehensive installation cost is 2 - 3 times that of branded products, and there are also safety hazards caused by unqualified welding quality. Moreover, the procurement cost may incur high rework costs later due to quality problems.
2. Insufficient after-sales support: Some small manufacturers lack the ability to provide full-process one-stop services, and it may be difficult to get timely solutions when problems arise later.
