What is the main advantage of using engineered I-beams over traditional lumber beams?

Engineered I-beams are specifically designed to provide an increased strength-to-weight ratio compared to traditional lumber beams. This means they can support heavier loads while being lighter, which makes them easier to handle and reduces the overall structural load. The design of I-beams allows for more efficient use of materials, resulting in a beam that can span longer distances without the need for additional support. This enhanced structural capability can lead to more flexible design options in construction, as well as potentially saving on overall material costs when considering structural requirements. The manufacturing process of these beams also ensures consistency in strength and performance, which can be an advantage over natural wood that may have variations and weaknesses.
