q345a-carbon-steel-h-beam is an economic section efficient section with a more optimized cross-sectional area distribution and a more reasonable weight-to-weight ratio. It is named because its section is the same as the English letter "H". With each part of the H-beam arranged at a right angle, the H-beam has advantages of strong bending resistance, so it is widely used in simple construction, cost saving, light weight structure and son on.
