FAQ:
Q1: Are you a trader or manufacturer?
A1: We are the professional manufacturer with 16 years experience,
located in Wuxi City which is a famous stainless steel production
base. Welcome to our factory before you place order.
Q2: What is your major market?
A2: 95% of our tubes export. We mainly sell to America, Canada,
Australia, Japan, Russia, Germany, France, Dubai, Brazil, Chile,
India, Thailand, South Africa, Egypt, Nigeria, etc.
Q3: What's the annual output?
A3: We can produce more than 31,000 tons stainless steel tubes in a
year.
Q4: What is your welding method?
A4: All of our tubes are welded by TIG welding methods. Our tubes
can get fully welding and smooth inner welding, without blisters,
leak welding or black line. All of our tube are good for tube
bending.
Q5: How do you control the quality during the polishing process?
A5: 1)As for the mirror polish square/rectangular tube, we will
polish it as least four times.
2)During the polishing processing, we set a special sanding wheel
to polish the welding part.
3)To avoid scratches, after polishing, the tubes will be lay out on
a steel crate then we could lift the whole steel crate instead of
the tube.
4)On the other hand, we use the gunny bags to protect the tube's
surface when the tube laying-out.
Q6: How do you inspect the tubes?
A6: The Quality inspectors inspect the tubes during each production
processes from raw material, tube welding, polishing, packaging.
1) Before the production of each machine, we will have the first
checked and record the data.
2) During the production, our inspector and engineer have been
carefully moniting and we record the data every two hours.
Q7: What is the MOQ?
A7: 3tons.
Q8: What’s the delivery time for the tubes normally in your
company?
A8: 20-30 days for 1-4 containers base on the how many items.
Q9: What payment terms you can deal with?
A9: Mostly we deal with TT terms and L/C,for L/C we need to know
