Iron Plate of Container Mobile House

The iron plate of container mobile houses is typically composed of a steel structural frame paired with enclosure panels, with core materials being color-coated steel plates or special steel plates. The thickness and coating process need to be selected based on the usage scenario. The following elaborates on material types, performance requirements, and process improvements:

I. Basic Material Types and Structures

The main body of the iron plate in container mobile houses consists of two parts:

1. Steel Structural Frame: Utilizes welded or bolted square steel, C-shaped steel, etc., to form the load-bearing structure of the house. For example, Baotou Xinxing Color Plate Steel Structure Manufacturing Co., Ltd. installs C-shaped steel purlins between the bottom beams to distribute the load to the main beams, maintaining structural stability even when the container is stacked three layers high.
2. Enclosure Panels: Mostly color-coated sandwich panels (such as rock wool or polystyrene sandwich), with an outer layer of galvanized or aluminized zinc steel plate and an inner layer of moisture-proof and sound-insulating materials as needed. The side panels of Beijing Falilai's container mobile houses use special sound-insulating and heat-insulating fillers, also providing fire protection.

II. Performance Requirements and Material Selection

1. Strength and Durability:

   • The thickness of the steel directly affects the load-bearing capacity. Ordinary suppliers often use 4mm thick square steel for the container's vertical columns, while transformed enterprises adopt 6mm thick square steel and add stiffeners, increasing the compressive strength by about 50%.
   • Anti-corrosion processes are crucial. Baotou Xinxing Company performs shot blasting and rust removal on the container's surface, followed by spraying zinc-rich primer and polyurethane topcoat. This protective system can maintain the effective lifespan of the steel for over 15 years in environments with wind and sand and temperature differences in northwest China.

2. Environmental Adaptability:

   • Thermal Insulation and Condensation Control: Jining experiences long winters and significant temperature differences, requiring targeted adjustments to the panel coating. For example, using a high weather-resistant polyester resin coating on the outer layer and adding a moisture-proof aluminum foil layer on the inner layer can reduce the probability of condensation and meet thermal insulation requirements in environments as cold as -30 degrees Celsius.
   • Wind and Earthquake Resistance: The quick-assembly containers from Suzhou Zhongnan Steel Structure Co., Ltd. adopt a full steel structural frame, achieving a wind resistance rating of Level 12 and an earthquake resistance rating conforming to the GB50011-2010 standard, suitable for coastal or earthquake-prone areas.

III. Process Improvements and Detail Optimizations

1. Cutting and Bending Precision:
   The cutting precision and bending angle differences of the panels directly affect the airtightness of the container. Professional suppliers use CNC bending machines to control the bending angle of the door frames within ±0.5 degrees and adopt ethylene propylene diene monomer rubber seals, which have better weather resistance than ordinary silicone seals and a service life of over 5 years.

2. Modularization and Standardization:

   • Baotou Xinxing Company integrates pre-buried pipelines into the container's chassis and adopts quick-connect designs to reduce on-site construction errors.
   • The quick-assembly containers from Suzhou Zhongnan support on-demand splicing and combination, with internal partitions that can be quickly adjusted to adapt to multiple scenarios such as engineering camps and commercial temporary spaces.
