4x12 Wood Beam Overview. 4x12 Wood Beam is a large-sized lumber commonly used in heavy construction for structural support, beams, and large framing. Below are its key details: Nominal Size: 4 inches × 12 inches Actual Size: Typically 3.5 inches × 11.25 inches (89mm × 286mm) Materials: Made from softwood (e.g., Douglas fir, pine) or hardwood (e.g., oak, maple).
Applications of Douglas Fir Span Charts. Floor Joists: Douglas fir is widely used for floor joists due to its strength and rigidity. Roof Rafters: For roof framing, Douglas fir supports long spans, allowing for open spaces below. Beams and Headers: High-grade Douglas fir beams can support heavy loads and are often used in headers and load ...
A double 2×10 beam could typically span approximately 12 to 14 feet without additional support. How far can a 6×6 beam span without support? A 6×6 beam is a substantial piece of lumber often used in heavy-duty applications. Its span capability depends on similar factors as mentioned for the 2×10 beam. Assuming: Wood species: Douglas Fir-Larch

There are different size of beam like 4×6, 4×8, 4×10 and 4×12 made of different species of wood Southern yellow pine, Redwood, Hem-Fir, SPF, & Douglas-Fir with grade-1 & grade-2. The SYP is strongest species of wood that can span more distance compared to other species of wood.
Step 2: Specify Beam Span. The beam span is the distance between two supports of a beam; this is usually walls or columns. The larger the span is, the more massive the beam has to be in order not to bend and break. Normally, the span is measured in feet. Example: For instance, if the supports are 12 feet apart, placing the beam in between, the ...
