Flange vs. Web: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Flange is a projecting flat rim or collar used for attachment or strength, while web is the central part of a beam or structural member that connects flanges.
Key Differences
Flanges are the projecting edges, rims, or collars found on objects, often used to strengthen an object, for attachment, or for maintaining alignment. Webs, in structural terms, refer to the central part of a beam that connects the flanges and supports the structure against shear forces.

In the construction of I-beams or H-beams, the flange is the flat, horizontal section on the top and bottom, providing resistance against bending moments. The web is the vertical or diagonal part in the middle, which resists shear forces and provides stability.

Flanges are commonly found in pipes, where they are used for connecting pipes or attaching to other components. In contrast, a web is not typically part of a pipe but is a crucial component in structural beams and columns.

The purpose of a flange in various contexts is to provide a surface for fastening or for increasing surface area for load distribution. The web, however, primarily serves to connect different parts of a structural element and to withstand the stresses applied to it.

While flanges can be seen in everyday objects like wheels or camera lenses, where they help attach parts together or provide reinforcement, webs are more specific to structural engineering, playing a key role in the distribution of forces across a beam or framework.
