Square &Rectangular Pipe-Product Center-Shandong Keman Import & Export Co., Ltd.

Carbon square tubes are primarily made of carbon structural steel (such as Q235 and Q345) and high-quality carbon steel, with a carbon content ranging from 0.12% to 0.25%. They are processed through cold bending and welding (the mainstream process) or seamless rolling, resulting in square or rectangular cross-sections (rectangular square tubes are often collectively referred to as "carbon square and rectangular tubes"). Their core positioning is as a "general-purpose structural pipe," combining the high strength of steel with the lightweight advantages of a hollow cross-section. They can replace traditional profiles such as I-beams and channel steel, achieving "steel substitution and cost savings." They also possess excellent welding, cutting, and bending properties, adapting to various structural design requirements.

SS316L Galvanized Square Tube

Galvanized square tube is a square-section steel tube with a zinc coating on its surface. It is a hollow steel section made from hot-rolled or cold-rolled steel strip as raw material, which is cold-bent, high-frequency welded, and then hot-dip galvanized or electro-galvanized to form a zinc coating on the surface.
