What is flitch beam?

A flitch beam is a type of composite beam consisting of a steel plate sandwiched between two timber beams. This combination of materials creates a stronger and more rigid beam that can span longer distances than traditional timber beams alone.

Flitch beams are commonly used in construction to support heavy loads and span large distances, such as in bridge construction or in the framing of large buildings. They are also used in residential construction for supporting floor joists or roof rafters.

The steel plate in a flitch beam adds tensile strength to the beam, which helps to prevent sagging or bending over time. This makes flitch beams an attractive option for projects that require long spans or high load-bearing capacities.

Flitch beams are typically custom-made to fit the specific requirements of a project, and the size and thickness of the steel plate can be adjusted to meet the desired load capacity. They are often more expensive than traditional timber beams, but their increased strength and durability make them a cost-effective choice for many construction projects.
