Product Description

Product Description

Square pipe, a term for square tubing, is a steel pipe with equal sides. It is a strip of steel rolled after the process.Square tube is a hollow square cross-section lightweight thin-walled steel tube.Uses of square pipe include architecture, machinery manufacturing, steel construction and other projects, shipbuilding, solar power generation support, steel structure engineering, electric power engineering and so on.

Galvanized square tube is a kind of hot-rolled or cold-rolled galvanized steel strip or galvanized coil for the billet by cold bending processing and forming, and then by high-frequency welding made of square cross-section shape dimensions of the hollow square cross-section steel tube, or will be done beforehand cold-formed hollow steel tube and then hot-dip galvanized processed into galvanized square tube.
