How much does a beam cost?

Could you please clarify the context in which you're asking about the cost of a beam? Are you referring to a structural beam used in construction? Or perhaps you're inquiring about a different type of beam, such as a beam of light or a beam in physics? If it's a structural beam, the cost can vary significantly depending on the material used, its size, and the market conditions. Steel beams, for instance, tend to be more expensive than wooden beams due to their durability and strength. The price also fluctuates based on supply and demand. Moreover, if you're considering purchasing a beam, it's essential to factor in the cost of installation as well. Hiring a contractor or engineer for proper installation can add to the overall expense. Could you please provide more specific details about the beam you're inquiring about? This would help me give you a more accurate and relevant answer.
