Linyi Special Container House

Linyi special container houses mainly refer to container-style buildings with special functions or uses, covering types such as refrigerated container houses, engineering container houses, and modular container houses. They are widely used in temporary construction sites, commercial offices, cultural and tourism facilities, and special storage scenarios.

I. Main Types and Functions

1. Refrigerated Container Houses
   Produced by companies such as Junan Dongcheng Container Service Co., Ltd., these houses utilize extended freezer technology, offering refrigeration and preservation functions. The container sizes include specifications of 20, 40, 45, and 48 feet. Equipped with professional refrigeration units inside, they have a wide temperature control range and are suitable for scenarios such as food industry transportation, supermarket refrigerated storage, and pharmaceutical cold chains.

2. Engineering Container Houses
   Primarily featuring packed box and light steel keel structures, these houses adopt hot-dip galvanized cold-formed steel frames paired with fire-resistant polyurethane sandwich panels or rock wool panels, providing thermal insulation, fire resistance, and moisture resistance. They can be used independently or stacked in multiple layers and are commonly found in construction site dormitories, office areas, temporary meeting rooms, and emergency housing.

3. Modular Container Houses
   Developed by companies such as Qingdao Leiyue Heavy Industries, these houses achieve rapid construction through standardized module combinations, supporting customization of irregular sizes and internal functional divisions (such as bathrooms and kitchens). They are suitable for temporary housing needs in commercial streets, tourist attractions, new rural construction, and disaster relief.

II. Core Manufacturing Processes

1. Structural Processing
   Automated welding production lines are used to complete the welding of steel structural frames, with hot-dip galvanizing applied to the surface to enhance rust resistance. Wall and roof panels are filled with insulation materials (such as rock wool and glass wool) through composite processes and covered with metal panels or calcium silicate boards.

2. Functional Integration
   Water and electricity pipelines are pre-buried inside, supporting customization of doors, windows, electrical systems, and water supply and drainage systems. Some companies (such as Penghang Containers) can achieve flexible designs such as side doors and detachable columns to optimize loading and unloading efficiency or space utilization.

3. Quality Control
   Before leaving the factory, they must pass structural strength tests, airtightness tests, and trial assembly verifications to ensure component matching and construction safety. Some companies have obtained China Classification Society (CCS) factory approval and ISO environmental and occupational health and safety management system certifications.

III. Safety and Selection Considerations

1. Fire Safety
   Prioritize container houses filled with Class A fire-resistant materials (such as rock wool panels) and avoid using flammable sandwich panels such as polystyrene and polyurethane foam. Electrical circuits should be equipped with protective sleeves, and switch boxes should adopt metal galvanized surface-mounted designs.

2. Space Planning
   Determine container size and stacking layers based on the usage scenario, reserving a safety distance of at least 6 meters. For long-term usage scenarios (such as cultural and tourism homestays), it is recommended to choose light steel keel houses that support flexible customization of house types and appearances.

3. Supplier Evaluation
   Choose manufacturers with physical production workshops, standardized quality inspection systems, and customization service capabilities. Their production strength and service levels can be verified by conducting on-site inspections of production line busyness, on-site management order, and project cases.
