Quality Control Process
Quality control is integrated into each stage of manufacturing. Inspections are conducted from material preparation through final loading to help reduce potential issues during transportation and installation.
Material Inspection
Before production begins, key materials are checked to verify compliance with project specifications.
Inspection items include:
• Steel structure materials
• Wall panel materials
• Insulation materials
• Doors and windows
• Electrical components
• Plumbing accessories
Materials that do not meet project requirements are not used in production.
Structural & Welding Inspection
The structural frame forms the foundation of every modular building.
During production, inspection focuses on:
• Frame dimensions
• Welding consistency
• Structural alignment
• Joint connections
• Surface preparation
These checks help ensure assembly accuracy and transportation stability.
Assembly & Functional Inspection
After structural fabrication, each unit enters assembly and functional testing.
Inspection items include:
• Door operation
• Window installation
• Interior finishing
• Wall panel installation
• Electrical connections
• Plumbing systems
• Fixture installation
Any identified issues are corrected before the product proceeds to the next stage.
Finished Product Inspection
Before packaging, the completed unit undergoes a final inspection.
This includes:
• Exterior appearance review
• Interior condition inspection
• Dimension verification
• Hardware inspection
• Utility system verification
• Cleanliness and finishing checks
The purpose is to confirm that the product matches approved drawings and specifications.
Container Loading Inspection
Proper loading is critical for international shipments.
Before shipment, we inspect:
• Packaging protection
• Product securing methods
• Loading arrangement
• Container condition
• Accessory packaging
• Documentation consistency
This helps reduce the risk of transportation-related damage and ensures products arrive in good condition.
Inspection Records & Customer Updates
During production, customers can receive progress photos and videos upon request. Key production stages and final inspections can be documented to provide greater visibility into the manufacturing process before shipment.
