Ends fixed beam length, vertical midpoint bear jack 10t applied concentrated load of hot-rolled H-beam, span of 1.4 meters, requires 20b types of beams, corresponding deflection of 1.087mm, a safety factor of 1.68, material Q235B, I do not know where you want to use the I-beam symbol, this deflection can basically be used in all of the beam. But replaced by 18 # steel workers have the safety factor is too small, if it is to work piecemeal steel you can put it in the material change Q345B. Then I can change the 18 # steel workers. 18 # steel workers corresponding deflection of 1.65mm, a safety factor of 1.83, the material is Q345B. Meet under the higher cost compared to similar products, customers without increasing the cost to customer special requirements, such as some users require cutting power of machine beams, and some customers require high speed, high efficiency machine, which makes the profile bending machine business a significant advantage in the competition in the domestic machine tool industry. In addition, the development of industrial clusters, but also for marketing play a good propaganda effect. Beam Model | Hefei beam | Fair Trading by Bo Bo Trading Company Hefei exhibition.
