Global Logistics Service
Our experienced logistics team organises shipments to major international ports. Full sets of export documents are supplied to facilitate hassle-free customs clearance.
Q1: How can I confirm dimensions match my project requirements?
A: All items are customized according to your project drawings. We will produce shop drawings for your review and approval. Production only starts once you sign off on the confirmed drawings.
Q2: Can you offer one-stop solutions for construction projects?
A: Yes. Many villa clients order materials in smaller volumes. Our one-stop service helps cut down your workload and save valuable time.
Q3: What is the overall lead time?
A: Production takes 30–45 days after the order and shop drawings are confirmed. You also need to factor in customs clearance (7–10 days for each side) and ocean transit times ranging from 18–45 days, depending on destination ports.
We recommend reserving 3–4 months in total for procurement. Extra time is also required for design reviews and dimension verification, so it’s best to send your inquiry as early as possible.
Q4: What information do you need to prepare a quotation?
A: Please provide the stair floor-to-floor height and opening dimensions. Alternatively, share your project drawings so we verify all measurements.
Q5: Are stairs pre-assembled for testing at your factory?
A: Yes. Every set of stairs undergoes trial assembly in our workshop. We will share photos and videos for your confirmation before disassembling the units for surface finishing.
