Isolation Container House

For container houses used for isolation, it is essential to focus on structural stability, fire safety, installation efficiency, and compliance. Priority should be given to products from manufacturers that use all-steel structures, fire-resistant filling materials, modular designs, and possess professional qualifications.

1. Structural Stability is the Core Safety Indicator

As isolation facilities, container houses must be capable of withstanding wind and earthquakes. All-steel structural frames are superior to semi-welded and semi-bolted structures. For example, products from Suzhou Zhongnan Steel Structure Co., Ltd. use all-steel welding processes, with deformation of only 2mm under 12-level strong winds, well below the national standard limit of 10mm. In contrast, the semi-welded and semi-bolted structures from CIMC Modular Building Investment Co., Ltd. have a higher risk of bolt loosening after long-term circulation. Steel thickness and welding processes directly affect safety. The thickness of main beams and columns must meet standards, with full and void-free welds. The entire container body should be galvanized or coated with anti-corrosion treatment to extend its service life to over 15 years.

2. Fire Safety Must be Strictly Controlled

Fire hazards in isolation houses mainly stem from construction materials and electrical wiring. Filling materials must use Class A fire-resistant rock wool, avoiding flammable materials such as polystyrene and polyurethane foam. For example, a container fire in Hangzhou was caused by an electrical switch fault igniting weeds, while a fire in Tianjin Binhai New Area resulted in two deaths due to flammable materials. Electrical wiring must be protected with sleeves, with sockets and switch boxes using metal galvanized boxes and mounted openly. Simple fire-fighting equipment should be provided, with a spacing of over 6 meters between containers and heat and fire sources kept away from the houses.

3. Installation Efficiency and Reusability

Modular design can significantly shorten construction periods. For example, the packing-box units from Shandong Jinda Lvjian achieve an 85% factory prefabrication rate, with each module taking no more than 2 hours to install and 20 sets of work sheds being completed in 3 days. Reusability reduces the total lifecycle cost. Products from Suzhou Zhongnan Steel Structure use high-strength bolts for connections, eliminating the need for welding and supporting secondary disassembly and assembly, with a comprehensive cost 40% lower than traditional temporary buildings.

4. Compliance and Qualification Review

It is necessary to confirm that manufacturers possess qualifications such as the Code for Seismic Design of Buildings (GB50011-2010) and the Quality Management System (GB/T 19001-2016) to avoid purchasing non-standard products. For example, some inferior products on the market have a wind resistance of only 8 levels, making them prone to deformation and detachment under strong winds, with rework costs reaching 3-5 times the purchase cost.
