Product  Introduction:
Hot-dip galvanizing is the reaction of molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle iron and steel parts first. In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride.And then sent to the hot-dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life

FAQ

 

About Our service

 

Q1: Are you a trader or manufacturer?

 A1: We are the professional manufacturer with 22 years experience, located in Foshan City which is a famous stainless steel production base. Welcome to our factory and showroom 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?
