Requirement analysis
Product Analysis
Key Points of the Requirement
Define the product family—steel security doors, aluminum or uPVC windows, wooden or WPC doors, and the hardware set (multi-point locks, hinges, handles, closers)—with opening styles and dimensions. Specify glazing configuration (single, double, triple, Low-E), thermal-break requirements for aluminum profiles, air-tightness and wind-load ratings for the destination market, security grade for entrance doors, and fire rating where applicable.
Cost Structure Analysis
Profile or door-leaf material is the largest cost line, followed by glazing units and the hardware set, where branded multi-point locking systems can double the hardware cost of budget items. Assembly labor, weather sealing, and breakage-safe packaging add measurably. Project quantities allow profile extrusion and cutting optimization that piece orders cannot.
Estimated Cost Range
Indicative factory pricing: steel security doors $60–$250 per unit; aluminum windows $40–$150 per m²; uPVC windows $30–$100 per m²; multi-point lock hardware sets $10–$60. Project volumes of 300+ units typically negotiate 10–20% discounts. Final quotations depend on profile specification, glazing, hardware grade, and certification scope.
Procurement Considerations
Prioritize manufacturers who certify profile wall thickness and alloy grade, provide hardware cycle-test data (100,000+ open-close class) and air/water performance test reports to your standard. Verify security grade and lock-cylinder classification for entrance doors, request installation instructions and adjustment support, and confirm glass safety certification (tempered/laminated as required), packaging for glass-in-frame shipping, Incoterms, and delivery destination.
