FAQ
Q: How do you select the appropriate spring steel?
A: Generally, springs thinner than 18 mm use 60Si2Mn, while springs 18 mm or thicker are recommended to use SUP9/55CrMn or higher-grade alloy spring steel.
Q: Can I order samples before bulk production?
A: Yes. Sample orders are available for quality verification before mass production.
Q: What is the typical production lead time?
A: Normally 15–30 days after deposit. Orders with multiple specifications or special materials may require additional production time.
Q: Can you provide inspection reports before shipment?
A: Yes. A Product Inspection Report is available for every production batch upon request.
Q: What payment terms do you accept?
A: Our standard payment term is 40% T/T deposit, with the balance paid before shipment. Other terms can be discussed for long-term cooperation.
Q: What export services do you provide?
A: We provide export packing, customs documentation, commercial invoices, packing lists, certificates when required, and international shipping coordination.
Q: How should leaf springs be stored before installation?
A: Store them in a dry, well-ventilated warehouse, avoid prolonged exposure to moisture or corrosive environments, and keep the original packaging intact until installation.
