Quality Control
A quality-control page for buyers who want fewer specification mistakes, less rework, and a cleaner handoff from quotation to shipment.
Before production
- Drawing review and configuration confirmation
- Hardware and glass options confirmation (when applicable)
- Finish/color confirmation
Before shipment
- Packing method confirmation (carton + foam + pallet options)
- Surface protection checks
- Photo confirmation for key items and packing
Where quality problems usually begin
- Drawings are incomplete or opening logic is unclear
- Glass, hardware, or finish direction changes late
- Project labels and packing rules are not defined before production
- Mixed-category orders are quoted without a clean item structure
- Compliance expectations are mentioned only after configuration is fixed
What buyers can do to reduce rework
- Use one confirmed drawing set and one quantity baseline
- Define finish, glass, and hardware expectations in the RFQ stage
- Clarify whether the order is for distribution or project installation
- Confirm label and packing logic before the shipment stage
- Ask for photo confirmation when order complexity is higher
Quality flow in practical terms
- Confirm drawings, system direction, and key commercial scope.
- Lock finish, glass, hardware, and packing assumptions.
- Review labels, mixed-order grouping, and destination-specific notes.
- Check packing protection and shipment photos before dispatch.
