How to Suspend Ceiling in Container House

The ceiling suspension of container houses can refer to the light steel keel ceiling process, selecting appropriate materials and construction methods based on the characteristics of container houses. Details are as follows:

Ceiling Material Selection

The ceiling materials for container houses need to balance lightness, fire resistance, moisture resistance, and aesthetics. Commonly used materials include metal panels (such as aluminum ceiling panels), calcium silicate boards, and gypsum boards. Metal panels offer excellent fire and moisture resistance and are easy to install, suitable for industrial or modern minimalist styles. Calcium silicate boards have high strength and good fire resistance, and can be paired with paint or wallpaper to achieve diverse decorative effects. Gypsum boards are relatively low-cost but require proper moisture-proof treatment, suitable for dry environments. For personalized designs, wooden veneer panels can also be used, but it is essential to ensure that the wood has undergone fire and anti-corrosion treatment.

Construction Process

1. Snap Lines for Positioning
   Based on the floor height and design elevation of the container house, snap horizontal lines along the walls to mark the ceiling elevation and mark the keel spacing positions on the walls to ensure the flatness of the ceiling.

2. Install Hanging Rods and Keels

• Hanging Rods: Fix them to the steel structure at the top of the container using expansion bolts, with a spacing of 90-120cm to ensure even load-bearing.
• Main Keels: Connect them to the hanging rods using matching hangers, with the same spacing as the hanging rods. The hangers should be installed alternately in the forward and reverse directions to enhance stability.
• Edge Keels: Fix them to the walls using cement nails, with a spacing of about 30cm, and the spacing between wooden wedges should not exceed 40cm to prevent deformation.
• Sub Keels: With a spacing of no more than 60cm, they are used to fix the panels and need to be installed perpendicular to the main keels.

3. Panel Installation and Detail Handling

• Metal Panels/Calcium Silicate Boards: Directly snap them into the keel slots or fix them with self-tapping screws, with a screw spacing of about 20-30cm.
• Gypsum Boards: Fix them using stainless steel drywall screws, and fill the screw holes with rust-proof putty to prevent rusting and affect aesthetics.
• Joint Handling: When the keels are not long enough, connect them using special connectors, and the joints should be staggered. Leave a gap of 3-5mm between panel joints to prevent cracking due to thermal expansion and contraction.

Precautions

• Rust Prevention: The steel structure of container houses is prone to rusting. Before construction, apply rust-proof paint to metal components such as hanging rods and keels.
• Thermal Insulation: If comfort needs to be improved, thermal insulation materials such as rock wool or glass wool can be filled inside the ceiling.
• Ventilation Design: Container houses are highly airtight. Maintenance openings can be reserved in the ceiling or ventilation equipment can be installed to prevent moisture accumulation.
• Load-Bearing Limit: Avoid hanging overly heavy items on the ceiling to prevent structural deformation.
