Why Build a Container House?

Step-by-Step Guide to Building a Container House

Step 1: Install the Main Steel Frame Structure

1.1 Install the Bottom Beam Frame

• Lay out the corner joints and ground beams on a level surface.
• Connect corner joints using bolts — do not tighten fully yet to allow for later adjustments.
• Use a ruler to square the corners, ensuring the base forms a perfect rectangle.
• Check the horizontal level using a spirit level for a flat and even base.

1.2 Install Floor Purlins

• Begin with the two central purlins, adjusting them to match the corner joint spacing.
• Tighten the bolts once aligned, then install the remaining purlins.

1.3 Erect the Vertical Columns

• Install all four corner columns, checking vertical alignment with a level.
• Again, avoid overtightening bolts until final positioning is confirmed.

1.4 Install the Upper Frame

• Pre-connect the top long beams and corner joints on the ground.
• Lift the assembly and position it atop the vertical columns.
• Secure the joints with bolts, but leave them slightly loose for adjustment.
• Connect the short beams, then fully tighten all bolts.

1.5 Install Roof Purlins

• Repeat the floor purlin process: install the center roof purlins first,
• Ensure spacing matches both ends before fixing the remaining purlins.

Step 2: Install the Drainage System

2.1 Install Downpipes

• Attach sealing strips along the rear edge of the downpipe.
• Pre-embed the downpipe and fix it securely to the roof beam.

2.2 Secure the Drainpipe

• Fasten the drainpipe to complete the drainage structure.

Step 3: Install Wall Panels, Doors, and Windows

• Fix the bottom and top edges of the wall panels to the frame beams.
• A standard container unit includes 1 door and 2 windows, which can be customized.
• Install wiring (electrical circuits) during this phase.
• Secure wires with steel wire guides running through wall panels.
• Follow strict waterproofing practices for safe residential use.

Step 4: Install Ceiling Panels

• Fix two 30mm x 50mm ceiling purlins onto the top frame to support ceiling panels.
• Position the ceiling panels and secure both ends for stability.

Step 5: Install the Roof Steel Sheet

• Cut glass wool insulation to size and lay it evenly across the rooftop.
• Place the corrugated roof steel sheet on top and fasten securely.

Step 6: Install Floor Covering

• Apply floor adhesive evenly across the base.
• Lay and press down the PVC flooring sheet (linoleum) for a smooth finish.

Step 7: Install Corner Trims

• Fit decorative trims at the top, bottom, and side corners for a clean and secure finish.
