Because they are custom-engineered components, you should always consult a structural engineer to provide a specific bolting schedule and plate thickness for your project's load requirements. What is a Flitch Beam - English Heritage Buildings
in thickness. Timber should be structural grade, such as Douglas Fir or Laminated Veneer Lumber (LVL). buy flitch beam
The added steel core dramatically increases stiffness, reducing the "bounce" often felt in long-span timber floors. At the support points, the load must be properly transferred
Unlike pure steel I-beams, flitch beams allow for standard carpentry connections—you can nail or screw directly into the timber sides to attach joists or drywall. At the support points
Proper "composite action" depends on high-strength bolts (Grade 8.8 or better) spaced at regular intervals, typically on center, often in a staggered pattern.
At the support points, the load must be properly transferred. Often, the timber bears on the posts while the steel is bolted through the timber; these end connections must be engineered to prevent the wood from crushing. Common Applications
