Container House Painting and Reinforcement

Container house painting and reinforcement require a combination of structural reinforcement and surface coating treatment to enhance the stability and durability of the house through professional methods.

I. Structural Reinforcement Methods

1. Reserved Hole Reinforcement Method
   Reserved holes are made in the web plates of the top and bottom beams. The top and bottom beams of the upper and lower container layers are fixed using rectangular steel plates and connectors to achieve coordinated force bearing. This method can improve the load-bearing capacity of the beam components and is suitable for vertical reinforcement of multi-story container houses while maintaining standardized processing and convenient installation characteristics.

2. Corner Reinforcement Structure
   A combination design of reinforcement plates, connecting plates, and threaded rods is adopted, with adjustable reinforcement achieved through slides, threaded tubes, and rotating shafts. This structure can enhance the stability of the container corners and improve the overall resistance to deformation, especially suitable for the horizontal reinforcement needs of single-story houses.

3. Wind-Resistant Reinforcement Measures
   For parts such as the roof that are easily affected by wind forces, methods such as color steel plate reinforcement, adding support frames, or anchor bolts can be used to improve the wind resistance of the house. For example, the Tianjin Wuqing Meichang construction site achieved wind-resistant reinforcement of the container house roof through professional manufacturer design.

II. Surface Coating Treatment

1. Rust Removal and Corrosion Prevention
   Before coating, the rust on the container surface must be thoroughly removed using sandblasting rust removal or mechanical grinding processes to ensure that the metal substrate meets the Sa2.5 cleanliness standard, providing a good attachment base for subsequent coatings.

2. Coating System Selection

   • Water-based Container Paint: Suitable for steel structure surfaces, it has characteristics such as environmental friendliness and strong weather resistance, which can extend the service life of the house and enhance its aesthetics.
   • Fluorocarbon Spraying: Provides excellent corrosion resistance and self-cleaning properties, suitable for coastal or highly polluted environments.
   • Functional Coatings: Depending on the needs, fire-resistant, thermal insulation, or soundproof coatings can be selected to enhance the comprehensive performance of the house.

3. Construction Process Points
   Coating should be carried out in a dry environment with a humidity level below 85%. A three-coat system of “primer + intermediate coat + top coat” should be adopted, with the thickness of each coat meeting the specification requirements to ensure uniform coating without sagging. After construction, adhesion tests and film thickness inspections should be carried out to ensure coating quality.

III. Comprehensive Renovation Suggestions

Container house renovation should follow the principle of “structural safety first” and carry out functional upgrades on the basis of reinforcement. For example, through standardized renovation processes, rapid construction of residential, office, or commercial spaces can be achieved. At the same time, combining multiple processes such as rust prevention, sound insulation, and thermal insulation can improve the durability and comfort of the house. After renovation, the service life of the house can reach more than 20 years, and it has the environmental advantages of being movable and reusable.
