What is the difference between square tube and seamless square tube?

There are small differences between tubes of different names. For example, seamless square tube and square tube are collectively referred to as square tube, and seamless square tube is one of them. The four corners of the tube are round in shape, but the size of the tube is the same.

Square and rectangular tubes are industrial consumables, which generally involve large quantities of procurement. The procurement personnel also need to sort out relevant data during procurement. The above customized standards of seamless square and rectangular tubes manufacturers and the specification and size table of square and rectangular tubes can provide reference for procurement personnel, and more direct data will be generally provided by manufacturers.
