High Quality Galvanized Structure Steel Pipe Tube

High Quality Galvanized Structure Steel Pipe Tube

Product description

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.

Product Detaile

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
