Is the track steel often called channel or construction steel?
Rectangular steel can be used as upright post. The crossbeam and so on, characteristic is starts the thing quickly. (it is faster to weld than two to channel steel)If the bridge, house, girder, anyway, from the top down is pressed by I-beam, the most rational rail steel and general construction steel different, but I type strong forceRail steel is a high strength alloy steel. The requirements are strict and the properties are different
See what you do, oh. Anyway, with the "beam" on the general use of I-beamChannel steel is usually made of steel structures and is matched with other types of steel
Direct comparison of Wx or Wy, which big will indicate which bending better, more carrying capacity.
