Container House Sealing Standard

The sealing standards for container houses mainly involve materials, construction techniques, and acceptance requirements, ensuring waterproof, windproof, and anti-corrosion performance for long-term use without leakage.

1. Sealing Materials and Construction Requirements

The sealing performance of container houses relies on high-quality materials and precise construction techniques.

• Panel Seam Treatment: High-quality products adopt multi-layer waterproof construction, with all panel seams and screw points receiving reinforced sealing treatment, such as using sealing strips or specialized sealants to prevent cracking of the adhesive layer due to temperature fluctuations.
• Door and Window Sealing: Windows typically use aluminum alloy tempered coated hollow casement windows equipped with sealing strips, undergoing strict sealing treatment to ensure no rainwater penetration. The space between the door frame and the wall also needs to be filled with sealing materials to prevent water leakage through gaps.
• Wall and Roof Structure: Walls are constructed with Class A or B1 fire-resistant rock wool sandwich panels, offering flame retardancy, thermal insulation, and sound insulation properties. Simultaneously, full-welding techniques ensure overall stability, preventing rainwater intrusion through structural gaps. Roof design must consider drainage slopes to avoid water accumulation and leakage.

2. Sealing Techniques and Acceptance Standards

The precision of sealing techniques directly affects the waterproof performance of container houses, requiring strict inspection during the acceptance phase.

• Water Spray Test: Before delivery, a water spray test must be conducted to simulate heavy rain conditions and verify waterproof performance, ensuring no leakage occurs.
• Structural Stability: Welding techniques must meet standards, such as using high-strength light steel frames with anti-corrosion treatment. Hinges and tracks should be well-designed, ensuring a flat and seamless finish after deployment to prevent sealing failure due to structural deformation.
• Wind Resistance Rating: Sealing performance must coordinate with wind resistance capabilities. For example, products should meet a wind resistance rating of 10-12 to ensure no loosening or leakage occurs at door and window seams or wall joints during severe weather conditions.

3. Long-term Maintenance of Sealing Performance

The durability of sealing performance requires regular maintenance.

• Regular Inspection: During use, regularly inspect sealing strips, screw points, and other areas for aging or damage, promptly replacing any failed materials.
• Cleaning and Maintenance: Avoid exposing sealing materials to corrosive substances, such as paying attention to salt spray corrosion in coastal areas and regularly cleaning door and window surfaces as well as wall exteriors.
• After-sales Support: Choose manufacturers offering 24-hour online response and 48-hour on-site services to ensure timely repair of sealing issues, minimizing service interruptions.
