Supply quality galvanized steel galvanized z

Z cold-formed steel structure can be designed to meet the reasonable vehicle designer; can replace relatively thick hot-rolled steel. However, due to the more complex sections and thickness using thinned somewhat, bringing corrosion and strength, stiffness and other issues. In the P64G type boxcar side beams, for example, with new kinds of steel instead of the original Z equilateral angles, in order to increase its rigidity, it is required to design a car similar to that used on the border shape which the largest The disadvantage is that easy to standing water and dirt, increasing the speed of the surface corrosion. Thus, cold-formed steel Z materials used to have a certain resistance to corrosion. Since 1987, China's railway truck batch using weathering steel, its material is 09CuPTiRE. Three cold-formed steel Z originally developed for use on gondola have adopted this copper phosphorus series of weathering steel. Scientific test and application test all Description: This weathering steel. General corrosion resistance equivalent to about 2 times the ordinary carbon steel, which is equivalent to three times in harsh environments. By 2001, the main type of railway wagons, have adopted the open boxcar this is weathering steel, along with the development of overloading, the main railway speed technology policy, the choice of structural steel high weatherability, high strength to reduce vehicle weight, improve vehicle performance problem is particularly prominent and urgent. To meet this direction, Z cold-formed steel in the selection should be developed as a starting point. Railway Passenger binding on weathering steel usage and future requirements of railway steel, resistance should be increased by one grade steel is used in the original basis of the resistance and intensity level, which is now Universal reduce weight materials used boxcar - 09CuPCrNi-A, the yield strength of 345Mpa, corrosion resistance equivalent to 2-3 times that of ordinary carbon steel, in the harsh environment equivalent to more than 3 times. On the rigidity, since Z-shaped steel cold-formed sections by designers to design, unlike the stereotypical hot-rolled profiles as limited. In P64G type boxcar develop four cold-formed steel Z, for example, the cross-section flexural modulus of elasticity are close or equal to the replacement of hot-rolled steel, while the structural design can have greater flexibility.
