Product Parameters

Product introduction
It is a square tube, and many kinds of materials can form a square tube, which is used for what and where. Most square tubes are made of steel pipes, which are unpacked, flattened, curled and welded to form a round tube, and then rolled into a square tube and then cut into the required length.
Performance of square tube:		The properties of square tubes mainly include plasticity, fatigue, strength, hardness and impact toughness.1. Plasticity refers to the ability of metal materials to produce plastic deformation without damage under the action of load, which is a very important parameter to measure the performance of a square pipe, which should not be overlooked when purchasing.2. Fatigue refers to the fatigue of the square pipe under cyclic load, which affects the service life of the parts. When purchasing the square pipe, choose the product with appropriate fatigue value as needed.3. Strength refers to the ability of metal materials to resist damage under the action of static load, which is also a matter that needs to be emphasized and paid attention to in many projects. According to the different ways of load action, it can be divided into tensile strength, bending strength, telescopic strength and shear strength.4. Hardness refers to the degree of hardness of metal materials, and the common expressions of square tube hardness include Rockwell hardness, cloth hardness and Vickers hardness.5. Impact performance is also an important index, which refers to the ability of metal to resist impact damage under impact load.
The purpose of the square tube:		Square pipes are used in construction, machinery manufacturing, steel construction and other projects, shipbuilding, solar power generation support, steel structure engineering, electric power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, highway railings, housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, lifting and transportation machinery and other welded structural parts with high loads.
