How to Make a Double 2×8 Beam?

Are you looking to add some extra strength and stability to your construction projects? Look no further than the double 2×8 beam! This versatile and reliable building component is a game-changer when it comes to creating sturdy structures. Whether you’re building a deck, framing a house, or constructing any other type of load-bearing structure, knowing how to make a double 2×8 beam is an essential skill for any DIY enthusiast or professional builder. In this blog post, we’ll dive into what exactly a double 2×8 beam is, explore its benefits, and walk you through the step-by-step process of making one yourself. So let’s get started on mastering this vital technique that will elevate your construction projects to new heights!

What is a double 2×8 beam?

A double 2×8 beam is a structural element made by joining two pieces of lumber measuring 2 inches by 8 inches together, side by side. It creates a stronger and more durable beam that can support heavier loads compared to a single 2×8 beam. The term “double” refers to the fact that two separate boards are used to create this composite beam.

The beauty of using a double 2×8 beam lies in its ability to distribute weight evenly across its width, making it ideal for load-bearing applications. By combining two individual beams, you effectively increase the overall strength and stability of your structure.

One of the key advantages of a double 2×8 beam is its versatility in various construction projects. Whether you’re building decks, pergolas, or framing interior walls, this type of beam proves invaluable in providing added support where it’s needed most.

Moreover, not only does a double 2×8 beam offer superior strength and durability but it also provides excellent resistance against warping or bending over time. This ensures long-term stability for your structures and reduces the need for costly repairs or replacements down the line.

If you’re looking to enhance the structural integrity and load-bearing capacity of your construction projects, incorporating a double 2×8 beam is an excellent choice. Its ability to provide exceptional strength while maintaining longevity makes it an indispensable component in any builder’s toolkit.

The benefits of a double 2×8 beam

A double 2×8 beam offers numerous benefits when it comes to construction and structural integrity. First and foremost, this type of beam provides exceptional strength and support due to its design. By combining two 2×8 pieces of lumber side by side, the resulting beam is able to handle heavier loads compared to a single piece of lumber.

Additionally, using a double 2×8 beam allows for longer spans without the need for additional supporting columns or posts. This not only increases flexibility in design but also creates more open space within a structure.

Another advantage is that double 2×8 beams are relatively easy to construct and install. With basic woodworking skills and tools, builders can create these beams on-site or purchase them pre-made from suppliers.

Furthermore, this type of beam offers cost savings as it requires less material than alternative options while still providing sufficient strength. It can be an economical choice without compromising on durability.

Opting for a double 2×8 beam in your construction projects brings multiple benefits including enhanced structural stability, greater design versatility, ease of installation, and potential cost savings.

How to make a double 2×8 beam

A double 2×8 beam is a strong and sturdy structural component that is commonly used in construction projects. It consists of two pieces of lumber, each measuring 2 inches by 8 inches, which are fastened together to create a wider and more robust beam.

To make a double 2×8 beam, you will need the following materials: two pieces of 2×8 lumber that are at least as long as the desired length of your beam, wood glue, clamps, and screws or nails for reinforcement.

Start by laying one piece of the 2×8 lumber on a flat surface. Apply wood glue along the entire length of one side. Then place the second piece of lumber on top, aligning it carefully with the first piece to ensure they are flush.

Once aligned, use clamps to hold the two pieces tightly together while the glue dries. Make sure to apply enough pressure so that there are no gaps between the boards.

After allowing sufficient time for drying (refer to manufacturer’s instructions), reinforce the bond by driving screws or nails through both boards at regular intervals along their length. This will provide additional strength and stability to your double 2×8 beam.

Remember to follow all safety precautions when working with tools and equipment. Always wear protective gear such as goggles and gloves, and work in a well-ventilated area if using adhesive products.

By creating a double 2×8 beam instead of using a single board, you can increase load-bearing capacity and reduce deflection in your construction project. This makes it an ideal choice for supporting heavy loads or spanning longer distances compared to single beams made from smaller-sized lumber.


In this article, we have discussed the concept of a double 2×8 beam and its benefits. By using two pieces of 2×8 lumber, you can create a strong and sturdy beam that is ideal for various construction projects.

The benefits of a double 2×8 beam are numerous. It provides increased load-bearing capacity compared to a single piece of lumber. This makes it suitable for supporting heavy loads or spanning longer distances without sagging.

Constructing a double 2×8 beam allows for greater flexibility in design and construction. By sandwiching two pieces of lumber together with adhesive and fasteners, you can create custom-sized beams that fit your specific needs.

To make a double 2×8 beam, follow these steps:

1. Start by selecting two high-quality pieces of pressure-treated or kiln-dried 2×8 lumber.

– Ensure that the boards are straight and free from any cracks or defects.

– Cut them to the desired length if necessary.

2. Apply an even layer of construction adhesive along one side of each board.

– Use an adhesive specifically designed for bonding wood surfaces together.

3. Place one board on top of the other so that their edges align perfectly.

– Make sure both ends are flush as well.

4. Secure the boards together using galvanized screws or nails at regular intervals

– Drive fasteners through both boards to ensure they stay firmly connected.

5- Allow sufficient time for the adhesive to dry according to manufacturer’s instructions before putting any load on the beam.

– This typically takes around 24 hours but may vary depending on environmental conditions.

Remember always to consult local building codes and regulations when constructing any load-bearing structure like beams.

By following these simple steps, you can easily create your own double 2×8 beam for use in various construction projects!
