How are structural steel beams made
Structural steel beams are construction materials that have a specific cross-section and are used to support loads and provide stability. There are two primary ways to fabricate steel beams: welding and hot rolling.
Welding: This method involves joining separate structural steel plates together by heating and melting the edges until they fuse. The plates can be shaped and cut to form different types of beams, such as I-beams, H-beams, or plate girders. Welding can reduce the weight of the beam and increase its strength, but it also requires more skill and equipment than hot rolling.
Hot rolling: This method involves heating the steel until it becomes soft and malleable, and then passing it through a series of rollers that shape it into the desired cross-section. The steel is then cooled and cut to length. Hot rolling can produce standard shapes such as I-beams, Z-beams, or C-beams. Hot rolling is faster and cheaper than welding, but it also produces more waste and less precise dimensions
