Composite beams are constructed from more than one material to increase stiffness or strength (or to reduce cost). Common composite-type beams include I-beams where the web is plywood and the flanges are solid wood members (sometimes referred to as engineered I-beams). Pipe beams sometimes have an outer liner made from another type of material.
