Product Description
100mm X 100mm 321 304 Stainless Square Rectangular Steel Pipe Tube
Product Description:
Square Tube is made the same way as pipe. During the manufacturing process flat steel plate is gradually changed in shape to become round where the edges are presented ready to weld. The edges are then welded together to form the mother tube. During the manufacturing process the mother tube goes through a series of shaping stands which form the round HSS (mother tube) into the final square or rectangular shape. China manufacturers follow the standard GB/T3094-2012.Most American manufacturers adhere to the ASTM A500 or newly adopted ASTM A1085 standards, while Canadian manufacturers follow both ASTM A500 and CSA G40.21. European hollow sections are generally in accordance with the EN 10210 standard.

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?
