 I. Overview: 
 Square Tube Introduction As the name suggests, it is the square shape of the tube, the material of a variety of materials can form a square tube, it is medium in doing, with where most of the square tube steel pipe for the majority, mostly for structural square tube, decorative square tube, building square tube. 
 Second, the detailed description: 
 Square Tube Introduction As the name suggests, it is the square shape of the tube, the material of a variety of materials can form a square tube, it is medium in doing, with where most of the square tube steel pipe for the majority, mostly for structural square tube, decorative square tube, building square tube. 
 Square tube, square pipe, a name, that is, the side looks of steel. Is the strip after the treatment process rolling made. To strip after unpacking, smooth, curl, welded to form the tube into a square tube and then cut into the required length and then by tube rolling. Generally, 50 per package. 
 Many years operating in Dongguan seamless square tube, square tube of large diameter in Dongguan, Dongguan, stainless steel tube, Dongguan thick-walled Rectangular Pipe the Dongguan galvanized square tube, the Dongguan 16mn square tube, the Dongguan Q345B square tube, rectangular tubes of Dongguan the Q235B large caliber the Dongguan square rectangular tubes 
 Square tube seamless and weld. 
 Seamless square tube is molded of a seamless tube extrusion. 
 A. Square tube performance index - plastic 
 Plasticity refers to the metal material in the loading, the plastic deformation (permanent deformation) without the capacity to destroy. 
 Two. Square tube index of performance analysis - hardness 
 The hardness is a pointer to measure the hardness of the metal material. Determination of hardness in the production method is the most commonly used is the indentation hardness method, which is under a certain load with a certain geometry of the indenter pressed into the metal surface to be tested, to determine the hardness value according to the degree of being pressed into. 
 Common methods are Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV) method. 
 3. Square tube performance index - fatigue 
 Discussed earlier, strength, ductility, hardness, are the mechanical properties of metals under static loading pointer. In fact, many machine parts working under cyclic loading, under such conditions, parts will fatigue. 
 4. Square tube performance index - the impact toughness 
 Known as the impact load in the load on the parts to the great speed of the role of metal called impact toughness under impact loading, the ability to resist damage. 
 5 Square tube index of performance analysis - strength 
 Intensity refers to the metal material to resist damage (excessive plastic deformation or fracture) performance in the static load effect. As the load mode of action of the form of tension, compression, bending, shear, so the strength is also divided into the tensile strength, compressive strength, flexural strength, shear strength. Various intensities of certain frequent use is generally more to the tensile strength as the basic strength of the pointer.
