How It Works
Quality Inspection Process

At Durable windows Industry Co., Ltd., quality assurance is an integral part of every stage of production, from raw materials to final delivery. Our quality inspection process ensures that all windows, doors, curtain walls, aluminum windows, uPVC windows, and WPC doors meet international standards and exceed customer expectations.

Raw Material Inspection

All incoming materials, including aluminum profiles, uPVC profiles, glass, hardware, WPC panels, and accessories, are carefully inspected for specifications, dimensions, surface quality, and material consistency before production begins.

Dimensional & Assembly Inspection

During production, our technicians check frame dimensions, profile cutting, corner joints, hardware installation, and overall assembly accuracy. This ensures every window and door is properly manufactured and assembled according to approved specifications.

Performance Testing

Finished products undergo performance checks covering sealing, operation, strength, water resistance, air tightness, and thermal insulation where applicable. These inspections help ensure reliable performance for residential, commercial, and project applications.

Appearance & Surface Inspection

Each finished product is carefully examined for scratches, dents, color consistency, welding or corner quality, glass defects, and surface finishing. Only products meeting our appearance requirements proceed to final inspection and packaging.

 

Final Inspection & Packaging

Before shipment, our quality team performs a final inspection against customer specifications, drawings, quantities, and packaging requirements. Products are then securely packed with protective materials to minimize damage during handling and long-distance transportation.
