Product description
High Quality Galvanized Structure Steel Pipe Tube
Square tube is a kind of light thin-walled steel tube with hollow square section
also known as cold-formed section steel. It is a section steel with square section
shape and size, which is formed by cold bending and high-frequency welding with
Q235 hot-rolled or cold-rolled strip or coil as the base material. In addition to the
increase of wall thickness, the corner size and edge flatness of hot-rolled extra thick
wall square tube reach or exceed the level of resistance welded cold-formed square
tube. Good comprehensive mechanical properties, good weldability, good cold and hot
workability and corrosion resistance, and good low-temperature toughness.
Square tubes are used for high load welded structural parts such as construction
machinery manufacturing, steel structure engineering, shipbuilding, solar power
generation support, steel structure engineering, electric power engineering, power
plant, agricultural machinery, glass curtain wall, automobile chassis, airport, boiler
building, highway railing, housing construction, pressure vessel, oil storage tank, bridge
power plant equipment, lifting and transportation machinery, etc.

Galvanized steel structure has many characteristics and advantages, such as firmness, zinciron
miscibility and strong wear resistance;; With good ductility, the alloy layer and steel firmly attached
to the substrate, so hot plating can be formed by cold stamping, rolling, stretching, bending and
so on without damaging the coating
