Which beam is mostly used in construction?
Could you please elaborate on which type of beam is most frequently utilized in construction projects? I'm curious to know whether it's the steel beam, concrete beam, or perhaps some other material. Could you also discuss the reasons behind its popularity? Is it due to its strength, durability, cost-effectiveness, or a combination of these factors? Additionally, how does this beam compare to others in terms of performance and longevity? I'm interested in understanding its advantages and disadvantages in the construction industry.
