FAQ
Q: Which spring steel material should I choose?
A: For spring thickness below 18 mm, 60Si2Mn is generally recommended. For thickness of 18 mm or above, SUP9/55CrMn or higher-grade materials are recommended for improved strength.
Q: Can I order samples before placing a bulk order?
A: Yes. Sample orders are available, subject to stock or production scheduling. Sample and freight charges are discussed individually.
Q: What is your typical production lead time?
A: Normally 15–30 days after deposit confirmation. Orders with multiple specifications or uncommon materials may require additional production time.
Q: Can I inspect the goods before shipment?
A: Yes. Factory inspection, third-party inspection, and batch inspection reports are available before shipment upon request.
Q: Do you accept mixed loading with different OEM numbers?
A: Yes. Multiple OEM numbers and specifications can be consolidated into one shipment based on MOQ and production planning.
Q: How should leaf springs be stored before installation?
A: Store them in a dry, well-ventilated environment on suitable pallets, avoiding prolonged exposure to moisture or corrosive chemicals. The electrophoretic coating provides additional protection during storage.
