Glulam beam weight per cubic foot
A Glulam (glue-laminated) beam is a type of engineered wood product commonly used in construction for its strength and durability. It is composed of multiple layers of dimension lumber (typically spruce, pine, or fir) that are bonded together with industrial adhesive.
The weight of a Glulam beam per cubic foot can vary depending on several factors such as the species of wood used, the thickness of each layer, and the type and amount of adhesive used in the bonding process. Generally, the weight of a Glulam beam ranges from 30 to 48 pounds per cubic foot.
The weight of Glulam beams is significantly less compared to solid timber beams of the same size and strength. This is because the laminating process removes any defects in the wood, resulting in a stronger and more uniform product. Additionally, the bonding process allows for a wider variety of wood species to be used in the production of Glulam beams, giving engineers more flexibility in selecting the right beam for their project.
The weight of Glulam beams per cubic foot is also affected by the size and shape of the beam. Larger beams will naturally weigh more than smaller ones due to the added volume of wood. Similarly, beams with complex shapes, such as curved or tapered beams, may have a slightly higher weight due to the additional cutting and shaping involved in the manufacturing process.
It is important to note that the weight of Glulam beams may vary slightly between manufacturers, as each company may have a different set of manufacturing processes and material specifications. Therefore, it is essential to refer to the product specifications from the specific manufacturer when determining the weight of Glulam beams for a project.
In summary, the weight of Glulam beams per cubic foot can range from 30 to 48 pounds and is influenced by factors such as wood species, layer thickness, and type of adhesive used. Glulam beams offer a lightweight and cost-effective alternative to traditional solid timber beams, making them a popular choice in the construction industry.
Glulam beam weight per board foot
Glulam (glue laminated timber) beams are a popular choice for structural applications in construction due to their strength, durability, and sustainability. They are made by bonding multiple layers of dimension lumber together with waterproof adhesive, providing a strong and stable material for supporting heavy loads.
The weight of a glulam beam per board foot varies depending on the species of wood used, the size and thickness of the beams, and the moisture content. In general, the weight of glulam beams is comparable to that of solid sawn timber, but they can be lighter due to their efficient use of materials.
The weight of glulam beams is typically measured in pounds per square foot (psf) or pounds per linear foot (plf). For example, a 4×8 glulam beam would have a weight of approximately 5.5 psf or 3.67 plf, while a 4×12 beam would weigh 8.25 psf or 5.5 plf.
To calculate the weight of a glulam beam per board foot, you will need to know the size and thickness of the beam, as well as the density of the wood species. The weight per board foot can then be determined by multiplying the density (in pounds per cubic foot) by the cross-sectional area of the beam (in square feet).
Here are some approximate weight ranges of glulam beams per board foot for commonly used wood species:
– Douglas Fir-Larch: 3.0 – 4.9 lbs/bdft
– Southern Pine: 3.3 – 5.1 lbs/bdft
– Hem-Fir: 2.5 – 4.3 lbs/bdft
– Spruce-Pine-Fir (SPF): 2.3 – 3.5 lbs/bdft
As an example, let’s calculate the weight of a 4×10 Douglas Fir-Larch glulam beam with a length of 20 feet. Using the above weight range, we can estimate the weight per board foot to be 4 lbs.
Weight of beam = (4 lbs/bdft) x (4 bdft) x (20 ft) = 320 lbs (approximately)
It is important to note that the weight of glulam beams per board foot can also be affected by the manufacturing process. For instance, glulam beams made with denser wood species or with a higher number of laminations will be heavier than those made with lighter wood species or fewer laminations.
In conclusion, glulam beams offer an efficient and lightweight solution for spanning long distances and supporting heavy loads in construction projects. The weight per board foot varies depending on several factors, but can generally be estimated by knowing the size and species of the wood used. It is always best to consult with a structural engineer to determine the appropriate glulam beam size and weight for your specific project requirements.

The weight of a glulam beam per meter can vary depending on several factors, including the type of wood used, the thickness and number of laminations, and the span of the beam. In general, the weight of a glulam beam per meter can range from 12 to 20 kilograms (kg). Thicker, heavier laminations will result in a heavier beam, while longer spans will also increase the weight per meter.
To determine the weight per meter of a glulam beam, the following formula can be used:
Weight per meter (kg/m) = (Width (m) x Height (m) x Density (kg/m3)) / Number of laminations
The density of the wood used for the laminations can vary, but is typically in the range of 400 to 500 kg/m3. For example, a 10-meter long glulam beam with a width of 0.3 meters and a height of 0.4 meters, made of 5 laminations of wood with an average density of 450 kg/m3, would have a weight per meter of:
(0.3m x 0.4m x 450kg/m3) / 5 laminations = 10.8 kg/m
It is important to note that this formula only provides an estimate of the weight per meter of a glulam beam, and the actual weight may vary slightly depending on the specific characteristics of the beam.
In conclusion, the weight of a glulam beam per meter varies depending on factors such as the type of wood, number of laminations, and span of the beam. It is important for civil engineers to accurately calculate the weight per meter of glulam beams in order to ensure the structural integrity and safety of construction projects.
