What is the Difference between Wood Beam Span and Size?
When it comes to selecting the right wood beam for your construction project, you may come across terms like “span” and “size.” While both terms relate to the physical dimensions of the beam, they serve distinct purposes.
Span: How Far Will It Stretch?
- Span refers to the distance between two supports, such as walls, columns, or other beams.
- It measures the horizontal distance the beam can cover without any additional support.
- Think of it like the “reach” of the beam.
Size: How Big is the Beam?
- Size, on the other hand, refers to the physical dimensions of the beam itself, such as its width, thickness, and length.
- This includes the beam’s dimensions, including the surface area and volume.
- Think of it like the “characteristics” of the beam.
To illustrate the difference, consider a simple example:
Imagine a wooden beam with a span of 12 feet, which means it can stretch between two supports 12 feet apart without any additional support. However, this beam might have a size of 6 inches by 6 inches by 12 feet (width by thickness by length), which describes its physical characteristics.
Understanding the difference between span and size is crucial when selecting the right wood beam for your project. The size of the beam determines its strength, durability, and performance, while the span determines its usable distance.
By carefully considering both factors, you can ensure your wood beam meets the demands of your project and provides the support and structure you need. Whether you’re building a deck, a house, or a bridge, getting the right beam is critical to its success.
