Galvanized steel pipe refers to the coating of a layer of zinc on the surface of ordinary steel pipes to prevent the steel pipes from being corroded and oxidized. Has the following characteristics and properties: 1. Strong corrosion resistance: The zinc layer on the surface of the galvanized steel pipe can prevent the steel pipe from being corroded and oxidized, thereby prolonging the service life. 2. Good high temperature resistance: the melting point of the zinc layer itself is as high as 419°C, which can withstand high temperature. 3. Good quality: It has a uniform zinc layer and can meet international standards. 4. Good aesthetics: the surface of galvanized steel pipe is smooth, durable and beautiful in appearance. 5. Wide range of applications: suitable for construction, petrochemical, electric power, mining, water conservancy and other fields. 6. Easy to process: Galvanized steel pipe is easy to process, such as cutting, welding, bending, etc. 7. Environmental protection: Compared with other corrosion protection methods, galvanized steel pipe will not produce environmental pollution.

Longitudinal welded pipe is a pipe material used to convey fluids and gases, consisting of multiple steel plates that are welded longitudinally. Following are the characteristics and properties of Longitudinal Welded Pipes: 1. High strength: Longitudinal welded pipe has high strength and can withstand high pressure and large physical load. 2. Corrosion resistance: The inner and outer surfaces of the longitudinal seam welded pipe are treated with anti-corrosion treatment, which has good corrosion resistance and can withstand corrosive substances such as acid, alkali and sea water. 3. Good plasticity and toughness: Longitudinal welded pipe has a smooth surface, good plasticity and toughness, and can be used for various complex shapes of pipes. 4. Beautiful: Longitudinal welded pipe has a beautiful appearance and is easy to install and maintain. 5. Wide application: Longitudinal welded pipes are widely used in industry, construction, shipbuilding, chemical industry and other fields. In short, longitudinal welded pipe has the characteristics of high strength, corrosion resistance, good plasticity and toughness, and beautiful appearance, and is an ideal pipe material.

This production line can realize deburring, chamfering, longitudinal straightening, and cut to the fixed length as customer's requirements. The output of the flat bar machine is low, but the added value of the finished product is high, especially in bright steel flat bar and stainless steel flat bar.
