HN350*175*7*11*16 in steel structure: H steel, 350mm high, 175mm wide, web thick 11mm, upper and lower plate thickness 16mm.
That is a high x steel beam flange width x x web thickness, flange thickness, flange width steel beam is as high as 300, 175, 7 for the web thickness, flange thickness is 11, 16 is the last R arc.
H section steel is a kind of economical section high efficiency profile with more optimized sectional area distribution and stronger weight ratio. It is named after the English letter "H". Because all the sections of H steel are arranged at right angles, H steel has been widely used in all directions for its advantages of high bending resistance, simple construction, cost saving and light weight.
