Frequently Asked Questions (FAQ)

Q: Can I request samples for stress testing?

A: Absolutely. We provide free samples for quality verification and fitment testing before bulk commitments.

Q: What is the difference between SUS304 and SUS316 for these washers?

A: SUS304 is ideal for most indoor and light outdoor use. SUS316 contains molybdenum, making it superior for preventing pitting in chloride/saltwater environments.

Q: Do you support custom branding and packaging?

A: Yes, we provide custom labeling, PE bags, and branded carton packaging for wholesale and retail distributors.
