Definition of cold drawn seamless square tube: 

Cold drawing: Cold drawing refers to the manufacturing process of optimizing and improving the cross section size, shape and performance of metal bars through multi-channel die cold extrusion.

Seamless: Seamless refers to the production process of the pipe without welding, so as to form a consistent material and structure on the internal and external surfaces of the pipe.

Square pipe: Square pipe refers to the pipe with a square or rectangular cross-section shape, which has high strength, stiffness and stability.
