What is the minimum acceptable depth for a beam support?

The minimum acceptable depth for a beam support is crucial for ensuring structural integrity and safety in construction. A depth of 89mm is deemed appropriate because it provides enough capacity to distribute loads effectively while maintaining the strength of the beam. Additionally, a depth of 89mm typically adheres to standard building practices and codes, which are designed to prevent issues such as bending and shear failure.

Choosing a support depth that is too shallow, such as 50mm, 75mm, or even 100mm, might not align with specific engineering requirements or could compromise the stability of the structure. Therefore, 89mm strikes a balance by being sufficient for most residential building needs, thereby promoting safety throughout the life of the structure.
