FAQ
Q1: Can you provide small-batch samples for testing?
Yes. We encourage and support customers in conducting material verification. We can supply small quantities of samples for each specification (e.g., 1-2 pieces per specification, approximately 300-500mm in length), which can be arranged for shipment before or after a formal order. Sample fees are subject to specific circumstances.
Q2: What is your minimum order quantity (MOQ)?
- In stock: No minimum order quantity
- Out of stock: Varies from 10 kg to 2 tons, depending on the material
Q3: What are your production and delivery lead times?
For standard stock products in common specifications, production takes 2-3 weeks after receiving prepayment. Exact timing depends on order volume and production scheduling.
Q4: What are the packaging methods?
We use export-standard packaging to ensure safe transit:
- Bars are bundled and tightly strapped.
- Outer layers are wrapped in moisture-proof paper/plastic film and placed on reinforced wooden pallets.
- Wooden crates can be provided upon customer request (additional charges may apply).
