Which beam your load-bearing wall opening gets
Engineered lumber, an LVL, suits residential spans up to about 5.5 m and costs $1,800 to $5,000 installed. It is lighter, easier to get into an occupied house and cheaper. Structural steel, a W-section, costs $3,500 to $9,000 installed and earns its price in two situations: a span longer than an LVL can carry, or a case where the beam has to be shallow enough to sit flush in the ceiling rather than dropping below it. That second reason is why many Toronto open-plan jobs end up in steel. A dropped beam across a kitchen and dining room is structurally fine and visually the thing clients often do not want, so the real question at the site visit is not only how far the opening spans but how much ceiling depth you are willing to lose. The engineer sizes it either way, and we price both where both work.
