Yantai Container House Frame

The container house frames in Yantai mostly adopt light-weight steel structures such as C-shaped steel, which are characterized by high strength, corrosion resistance, and easy assembly, serving as the core components for the structural stability of container houses.

I. Frame Material and Structural Features

The container house frames in Yantai primarily use C-shaped steel as the main material, with some adopting H-shaped steel or square tubes, connected by bolts to form a modular structure. This design offers the following advantages:

1. High Strength and Lightweight: C-shaped steel has a reasonable cross-section, strong bending resistance, and is relatively lightweight, facilitating transportation and lifting. For example, a standard container frame weighs about 1.5-2 tons but can withstand several tons of load.
2. Corrosion Resistance: The frame surface is galvanized or coated with anti-rust paint, adapting to the humid coastal environment and extending service life. Some high-end products use stainless steel to further enhance durability.
3. Modular Design: The frame is connected by standardized bolts without welding, allowing for rapid assembly into houses of different sizes (such as a 6m×3m standard container) and supporting horizontal expansion.

II. Functionality and Application Scenarios

The frame structure directly determines the performance of container houses:

1. Structural Stability: The light-weight steel frame, combined with walls (such as color-coated steel plates and rock wool boards), forms an overall load-bearing system capable of withstanding wind forces of up to magnitude 8 and minor earthquakes, suitable for scenarios like construction site dormitories and temporary offices.
2. Thermal Insulation: The frame is filled with glass wool or rock wool between the walls, combined with double-layer color-coated steel plates, achieving efficient thermal insulation. In summer, the indoor temperature can be 5-8℃ lower than the outdoor temperature.
3. Rapid Deployment: The frame has high pre-processing accuracy, requiring only 2-3 people for on-site assembly, and a single container can be installed within 6 hours, meeting urgent needs such as emergency rescue and post-disaster reconstruction.

III. Local Industrial Advantages in Yantai

As a production hub for container houses, Yantai's frame supply presents the following characteristics:

1. Complete Industrial Chain: Local enterprises (such as Penglai Senhao Integrated Housing) cover the entire process from steel production to frame processing, with controllable costs and quotations generally 10%-15% lower than the market average.
2. Customized Services: Support for personalized adjustments in frame size, load-bearing capacity, and window and door positions, such as designing strengthened frames with higher wind resistance for coastal scenic spots.
3. Leasing and Recycling System: Some manufacturers offer frame leasing services with daily rents of about 5-10 yuan per set, reducing short-term usage costs; retired frames can be recycled and refurbished, with a resource utilization rate of over 90%.
