When it comes to construction projects, it is important to make sure the design and materials used will ensure the safety of the structure and its occupants. The size of the wood beam needed to span 20 feet depends on several factors, including the load weight, wood species, and the type of beam used. This article will provide an overview of the different types of wood beams and what size wood beam is needed to span 20 feet.
Types of Wood Beams
The type of wood beam used in a construction project will depend on several factors, including the load weight, wood species, and the type of beam used. Generally speaking, there are three main types of wood beams: solid sawn, engineered, and laminated. Each type of wood beam has its own unique characteristics and benefits.
Solid Sawn Wood Beams
Solid sawn wood beams are made from a single piece of wood and are the most commonly used type of wood beam in construction. They are the strongest and most durable type of wood beam and can span up to 20 feet with proper support. However, they are also heavier than other types of wood beams and require more labor to install.
Engineered Wood Beams
Engineered wood beams are made from multiple pieces of wood that are glued together to create a strong and durable beam. These beams are lighter than solid sawn wood beams, making them easier to install. They are also less expensive than solid sawn wood beams and can span up to 20 feet with proper support. However, they are not as strong as solid sawn wood beams and may require additional support for larger spans.
Laminated Wood Beams
Laminated wood beams are made from multiple layers of wood that are glued together to create a strong and durable beam. These beams are lighter than solid sawn wood beams and require less labor to install. They are also less expensive than solid sawn wood beams and can span up to 20 feet with proper support. However, they are not as strong as solid sawn wood beams and may require additional support for larger spans.
What Size Wood Beam Do I Need To Span 20 Feet?
The size of the wood beam needed to span 20 feet depends on several factors, including the load weight, wood species, and the type of beam used. Generally speaking, a solid sawn wood beam that is 4×12 is the minimum size beam needed to span 20 feet, while a engineered or laminated wood beam that is 4×10 is the minimum size beam needed to span 20 feet. However, it is important to consult a structural engineer to ensure that the size of the wood beam being used is appropriate for the load weight, wood species, and the type of beam used.
Conclusion
When it comes to determining the size of the wood beam needed to span 20 feet, it is important to take into consideration the load weight, wood species, and the type of beam used. Generally speaking, a solid sawn wood beam that is 4×12 is the minimum size beam needed to span 20 feet, while a engineered or laminated wood beam that is 4×10 is the minimum size beam needed to span 20 feet. However, it is important to consult a structural engineer to ensure that the size of the wood beam being used is appropriate for the load weight, wood species, and the type of beam used.
