LVL beams come in varying widths, depending on the manufacturer you choose. Typically, the most widely used widths for LVL beams range from 3-1/2″ to 18″ in increments of 1-1/2″. The exact size of the LVL beam required for a particular application is based on the beam span, the span load, the allowable load, and the horizontal to vertical ratio.
So, the exact width of a beam may need to be determined for each individual job. For residential applications, a standard regular LVL beam width is usually 11-7/16″ and/or a wide LVL beam width of 13-7/8″.
What sizes does LVL lumber come in?
LVL (Laminated Veneer Lumber) is typically available in regular sizes that generally range from 1-3/4” to 11-1/2” wide with depths ranging from 7-1/4” to 18”. Different length packages for stock and construction-grade LVL include 9′ to 24′, depending on the manufacturer.
LVL is also available in other custom and special sizes per order. The standard thickness of LVL is typically between 11/16″ to 1-3/4″, and it commonly comes in 9-1/2″ and 11-7/8″ widths depending on the manufacturer as well.
Depending on the application and design, LVL is also available in symmetrical sections (from side to side) with tapered widths, and a variety of depths ranging from 7-5/8” and up (from a minimum of 12” to a maximum of 30”) with a common length of 12’, 18’ and 24’.
Additionally, LVL is available in a range of heights, including 7-1/4” and 7-3/4”.
How much does a 20 foot LVL beam cost?
The cost of a 20 foot LVL beam depends on a few factors, including what type of material you’re using and its quality, as well as the thickness and length of the beam. Generally, LVL beams vary in cost from $2 to $6 per linear foot, so a 20 foot beam could cost anywhere from $40 to $120.
It is recommended to get a quote from a local lumberyard to get an accurate estimate of the cost of the specific beam you’re looking for. In addition to the beam, you may need to include costs of any accessories, such as hangers or connectors, which could add an additional cost to your purchase.
What size LVL beam do I need to span 14 feet?
The size of the LVL beam needed to span 14 feet depends on a variety of factors, including the load being placed on the beam, the spacing and type of floor joists, as well as the live and dead load of the beam itself.
Generally speaking, when spanning 14 feet, a 4-ply LVL beam measuring 1-3/4 inches by 11-7/8 inches should be sufficient for an average load requirement. However, it is highly recommended to consult a licensed contractor or professional engineer in order to ensure that the most appropriate and safe size of LVL beam is chosen for the job.
How far can a LVL beam span without support?
The distance a LVL beam can span without support largely depends on the type of structure and the amount of load being applied. Generally, LVL beams are designed to span up to 22 feet depending on the support and design conditions.
Since LVLs are engineered wood products composed of several narrow wood laminates bonded together for strength, the size of the beam and the spacing of the supports will also affect the span. When considering LVL beam spacing, make sure that the LVL can handle the load at the desired span by using the appropriate spans from the tables in the LVL Manufacturer’s span guide.
The grade of the LVL, the spacing of the supports, as well as the species, grade and size of the lumber used in the beam should all be taken into account. Finally, when installing the LVL beam, it is important to use blocking to obtain the full load-carrying capacity of the LVL beam.
How wide is a LVL?
A typical LVL (Laminated Veneer Lumber) beam width can range anywhere from 3 1/4” up to 19” depending on the manufacturer and what the needs of the project are. The smaller the beam width, the lower the cost and the lower the capacity, while larger beam widths can increase the cost and capacity.
For a more specific answer, contact the manufacturer of the LVL you are considering for your project.
Can a 2×12 span 20 feet?
No, a 2×12 (two-by-twelve) beam cannot span 20 feet. This type of beam is used to span distances up to 14 feet, depending on the load it needs to bear and the spacing of the supports. A 2×12 isn’t considered to be a long-span type of beam and isn’t well-suited for spans over 14 feet.
To span 20 feet or more, a much larger beam made of a more durable or heavier material would be necessary. For example, a common long-span beam might be built out of steel, concrete, or larger-sized lumber.
Additionally, installing more vertical supports alongside the beam can help it span a larger distance.
What is the difference between an LVL and a Microlam?
An LVL (Laminated Veneer Lumber) is a type of engineered wood product made from layers of bonded wood veneers similar to plywood. It is often used for structural support in construction projects such as headers, beams, and trusses.
It is manufactured in a controlled environment to tightly control the size, shape, and orientation of the wood. LVL offers good strength and consistent dimensional accuracy, making it a popular choice for structural components in construction projects.
In comparison, a Microlam is a structural beam constructed of narrow laminations of wood. It is manufactured of layers of kiln dried lumber that are securely bonded with exterior-grade adhesives. It offers exceptional strength and a consistent depth.
Microlam beams are often used in floor systems and roof trusses, due to its ability to span long distances without needing additional support. It is also used in framing techniques that make use of space between two walls.
Microlams are more expensive than LVLs due to their greater strength and versatility.
