Hot-rolled H-beams are single, solid pieces of metal shaped during the rolling process at high temperatures, while welded H-beams are constructed by joining individual steel plates using welding. Hot-rolled beams are readily available in standard sizes, while welded beams offer more customization and can be made to specific dimensions not readily available in hot-rolled form.

Hot Rolled H Beam:

Advantages:
Lower production cost, consistent material properties, and good strength-to-weight ratio. 
Disadvantages:
Limited customization options and potential for less precise dimensions compared to welded beams.

Welded H-Beams:

Advantages:
Customization, potential for thinner sections and higher strength in certain applications, and cost-effectiveness for specific needs. 
Disadvantages:
Higher manufacturing costs, potential for weld-related stresses and distortions, and may require more rigorous quality control.
