When combined with wood, steel flitch Plates are used to create steel flitch beams for residential and light commercial construction. They're employed in the same way that built-up wood girders and headers (wooden beams that span the complete space they're supporting) are.
Finest steel flitch plates are commonly employed in the building of wood-based structures such as houses, decks, and roofs. They're particularly useful in renovation projects that aim to restore old wood, but they can be employed in a wide range of construction projects.

How do steel flitch plates/beams get their shape?
The term steel flitch plate can be somewhat confusing to consumers since it suggests it is made of steel however, it is mostly made of wood. Steel flitch plates consist of two wood beams (although there could be more than this added to reinforce the beam) and a flitch plate that is horizontally mounted between them and is joined and secured with bolts.
The correct bolting technique is crucial in ensuring that the weight that is applied to the beam is properly divided among the wood as well as steel plates.
Typically, the weight (or "load" is put in the beam's steel flitch that is high up on the beam (the wood part). Correct bolting ensures that the weight is uniformly distributed and moves towards the steel plate.
The flitch plate's steel component A36 Grade, 12", 34", and 1" Thick hot rolled steel in lengths up to 20' are commonly used in beam assembly. The beam's fabrication is also basic.
Two wooden beams are first trimmed to length to produce a flitch beam. The two beams are then fastened together with a prefabricated steel flitch plate (cut to length and drilled to suit bolt diameter). A composite beam is another name for this. The term composite refers to the creation of a single entity out of a variety of materials (steel and wood).
