    Hollow Section is a hollow strip steel, also

    known as flat tube, square tube or flat Fang

    Bian tube (as the name implies).A large

    number of used for conveying fluid pipe, such

    as oil, natural gas, water, gas, steam, etc.,

    in addition, in the bending and torsional

    strength phase at the same time, the weight

    is lighter, so also widely used in the

    manufacture of machinery parts and

    engineering structures.Also commonly used for

    the production of various kinds of

    conventional weapons, barrel, shells, etc.

    Hollow Section is to use hot rolled or cold

    rolled steel strip or rolled plate for the

    parent metal by cold bending forming by high

    frequency welding again after made of square

    cross section shape, the size of the

    steel.Hot rolled, thick-walled square tube in

    addition to outside in the thickness of the

    wall thickness, the size and edge Angle

    straightness achieves even exceed the level

    of the resistance welding cold forming square



    According to the type, can be divided in

    square pipe, retangular pipe and round pipe.

    According to the process, can be divided in

    hot rolled seamless steel square tube, cold

    drawn seamless tube, extrusion of seamless

    pipe, welded pipe.
