Frequently Asked Questions
Q1: Can this magnet be customized to other sizes or hole specifications?
Yes. Size, hole diameter, countersink angle, and magnet grade can all be customized.
Q2: Is this magnet suitable for outdoor or humid environments?
Nickel coating is suitable for general use. For humid or outdoor applications, epoxy or special coatings are recommended.
Q3: What is the minimum order quantity (MOQ)?
MOQ depends on customization level. Standard sizes may have lower MOQs. Please contact us for details.
Q4: Can samples be provided before mass production?
Yes. Samples are available and sample costs can be refunded upon bulk order confirmation.
Q5: Can the magnet be fixed using screws instead of relying only on magnetic force?
Yes. The countersunk hole design allows secure installation using standard flat-head screws, providing mechanical fixation in addition to magnetic holding force.
Q6: What magnet grades are available?
Common grades include N35 to N52. Higher grades offer stronger magnetic force within the same size. We can recommend the appropriate grade based on your load and application needs.
Q7: What packaging options do you offer?
Standard export packaging is used to ensure safety during transportation. Customized packaging and labeling are also available upon request.
Q8: What shipping methods are available?
We offer multiple shipping options, including express delivery, air freight, and sea freight. The recommended method depends on order quantity, delivery timeline, and destination.
