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

  1. Confirm drawings, system direction, and key commercial scope.
  2. Lock finish, glass, hardware, and packing assumptions.
  3. Review labels, mixed-order grouping, and destination-specific notes.
  4. Check packing protection and shipment photos before dispatch.
