4. Understanding “OEM Factory Price” — Key Cost Factors
When negotiating an OEM factory price, the following parameters determine the final quote:
Profile specification: Wall thickness (e.g., 1.6mm / 2.0mm), cross-section size, and alloy grade.
Glass configuration: Thickness (e.g., 5mm+5mm), air cavity (12mm / 16mm), optional argon filling, Low-E coating, or laminated glass.
Hardware brand: European or premium Chinese brands (e.g., GU, ROTO) affect cost and durability.
Surface treatment: Powder coating, anodizing, or wood-grain transfer, each with unique aesthetic and pricing differences.
Customization level: Non-standard sizes, special colors, or decorative glass patterns may add cost.
MOQ & packaging: Minimum order quantity and export packaging style (carton or wooden crate) also impact pricing.
A double-glazed casement door is more than an entryway — it’s a symbol of quality living.
With exceptional insulation, safety, energy efficiency, and design elegance, it adds long-term value to your building projects and brand reputation.
