aluminum i beam- Durable Structural Steel for Construction

With this capability, I beams can fully support an effective, efficient transfer of the loads borne by construction members. This means they have a high moment of inertia, an ability to resist forces which bend it, even under massive loads. It makes I beams the components of choice in traditional structural applications like beams, columns, and trusses. Flanges and the web together account for the bulk of the I beams' steel. This arrangement leads spare more heavily loaded parts inwards to where they are needed most: resisting bending.
