Thermal Insulated Container House Company
When purchasing thermal insulated container houses, it is essential to focus on the following core parameters and standards:
1. Thermal Insulation Performance Parameters
The thickness of the insulation layer directly affects the thermal insulation effect. Typically, a thickness of ≥75mm is required to meet the needs of low-temperature environments. The thermal conductivity of the material should be ≤0.024W/(m·K), such as high-efficiency insulation materials like polyurethane or rock wool. The sealing performance must pass air tightness tests to ensure there are no air leakage points at the seams of the container body, preventing the loss of cold air. For example, products from Qingdao Jiecheng Hongye adopt marine standards, with their thermal insulation performance verified through maritime transportation, enabling them to adapt to extreme temperature variations.
2. Power Supply Adaptability
It is necessary to confirm that the equipment voltage matches the power supply conditions at the site. Most industrial-grade thermal insulated containers are designed with 380V three-phase power, such as products from Qingdao Jiecheng Hongye, which support plug-and-play functionality. However, some civilian or temporary scenarios may require adaptation to 220V single-phase power. The power supply interfaces must have waterproof and dustproof ratings (e.g., IP54 or higher) to avoid short-circuit risks during outdoor use.
3. Structural Safety
The container body must be welded using high-strength steel (e.g., Q345B), with a wind pressure resistance rating of 8 or higher and seismic performance conforming to the GB/T 17742-2008 standard. Products from Shandong Guoheng Innovation have passed 72-hour airtightness tests, ensuring long-term use in complex environments. Additionally, it is necessary to inspect the container body for moisture and corrosion resistance treatments, such as hot-dip galvanizing or epoxy resin coatings, to extend the service life to over 15 years.
4. Inspection and After-sales Standards
Prioritize manufacturers that have passed ISO 9001 quality management system certification, such as Sichuan Shuozhan Zhuoxin Integrated Housing Co., Ltd. Their products must undergo full-process technical inspections before leaving the factory, including pressure tests and temperature cycle tests. The after-sales service terms should clearly specify response times (e.g., 24-hour technical consultation, 72-hour on-site handling) and service scope (e.g., lifelong structural safety maintenance guidance) to avoid uncontrolled maintenance costs in the later stages.
5. Modularity and Expandability
Standard container dimensions (e.g., 6055mm×2990mm×2896mm) should support horizontal/vertical splicing to meet composite functional needs such as office and accommodation. Products from Shandong Jinda Lvjian support multi-layer combinations, with a single container providing approximately 18㎡ of usable space, enabling the rapid construction of temporary command centers or emergency shelters. Additionally, it is necessary to confirm whether the container body supports non-standard customization (e.g., a maximum single container length of 12 meters) and special functional modifications (e.g., explosion-proof and cold-resistant modules).
