Frequently Asked Questions
How do I purchase doors/windows if I haven't imported from China before?
Simply send your required sizes and quantities along with your nearest port or address. We will provide an all-in quotation and manage the entire logistics process for you. For customized projects, AutoCAD drawings are recommended.
What customized services do you offer?
We provide full CAD product designs for real estate, hotels, hospitals, and villas. If required, we can also dispatch installation engineers for on-site service and guidance.
Is there a Minimum Order Quantity (MOQ)?
Yes, for doors, the MOQ is 7 sets. This is aligned with shipping company freight minimums (usually 1m³), which effectively covers about 6-7 standard door sets.
What is the typical delivery lead time?
Sample orders take 7-12 working days. Bulk orders for paint-free series take 13-16 days, while solid wood doors, aluminum products, or deep customizations take 28-36 days.
How is product quality ensured during inspection?
We offer three methods: 1. Internal QC with photo/video updates; 2. Welcome for agent/office inspections in our facility; 3. Third-party inspections by CCIC or BV to provide full credibility reports.
How do you guarantee safety during transportation?
We use heavy-duty packing materials, plastic protection for edges, and wooden crates for fragile items. Containers are loaded professionally to prevent shifting, and we provide marine insurance (CIF) to protect your investment.
