Daily Maintenance & Structural Protection Tips
Targeted scientific maintenance can effectively protect the integrity of the Q235B steel structure, delay aging and corrosion, and ensure long-term stable and safe operation of the folding container office in field environments:
Structural connection regular inspection: Regularly check the welding seams, fixing bolts and overall flatness of the Q235B steel frame to ensure tight connection and no deformation or looseness, eliminating potential safety hazards for double-layer office use.
Anti-corrosion coating maintenance & repair: Inspect the surface baking finish layer regularly, timely repair scratches and peeling areas, and isolate the steel structure from humid air and corrosive substances to maintain long-term rust resistance.
Scientific indoor load control: Avoid concentrated placement of ultra-heavy equipment and stacked sundries, keep uniform stress distribution of the steel frame, and prevent local structural deformation caused by long-term uneven load.
Site drainage & bottom protection: Choose flat and well-drained placement ground, timely clean surrounding water accumulation, avoid long-term soaking of the bottom steel frame, and prevent damp erosion affecting structural toughness.
Enclosed tightness daily check: Regularly inspect the sealing performance of doors, windows and wall joints to prevent rainwater penetration and dust accumulation indoors, protecting internal office facilities and slowing down structural aging.
