The fire resistance of container-based housing is a key focus of regulatory compliance reviews. As regulatory standards become increasingly stringent, many provinces and cities across China have explicitly mandated that temporary structures on construction sites must achieve a Class A fire rating. Project acceptance is primarily based on industry-standard documents such as the *Technical Specification for Container-based Modular Housing* (CECS 334:2013) and the *Technical Specification for Temporary Buildings on Construction Sites* (JGJ/T 188-2009). Some substandard products utilize sandwich panels that fail to meet fire safety requirements, posing a risk of toxic smoke generation when exposed to fire. Fangda Mofang products must comply with the basic performance requirements-covering fire resistance, seismic resilience, and thermal insulation-outlined in the *Technical Standard for Integrated Container-type Steel Structure Housing* (GB/T 51232-2016). Users should verify that the product's insulation core material is basalt wool (with a melting point exceeding 1,000°C) and that the thermal conductivity of the wall insulation material is below 0.035 W/(m·K).
Insulation materials that fail to meet fire safety standards can easily generate toxic smoke
Inadequate rust-proofing and water spray testing can easily lead to water leakage and structural corrosion
Structural Safety Risks: Substandard steel thickness and welding processes can easily lead to container deformation or even collapse. The structural strength of a container unit directly determines its service life and safety
