1. Can I get some samples?
Can provide small samples for free. Customized sample takes 5-7 days.
2. How about the delivery time?
Container order need 25-30 days.
3.Can I have customized packing with my logo?
Yes, we can follow your design, also we offer different types of packing, like bundle, woven bag, steel crate and wooden pallet / box.
4. How do you control the quality during production?
1) From raw material, forming, polishing, to packaging, we have QC for every process to do inspection, guarentee our products 100% qualified.
2) For mirror finish product, we will polish it as least 4 times.
3) To avoid scratches, after polishing, products will be lay out on a steel crate then we could lift the whole steel crate instead of the product itself.
4) We use the gunny bags twining on machine to protect the product surface when it laying-out.
