Engineered Wood Beam Size Calculator
Engineered wood beams are now key in construction for their strength and flexibility. They are a big deal in building structures today. This guide will show you how to pick the right size of these beams. We’ll talk about different types, the benefits, and what you need to consider when choosing their size.
There are special types of engineered wood beams, like LVL and PSL. They are made from wood materials that are put together using heat and pressure. This process makes them very strong, more consistent in shape, and sturdy. So, these beams can support bigger loads, cover larger distances, and keep their shape well.
Key Takeaways
- Engineered wood beams are made by bonding wood parts under heat and pressure.
- They are much stronger and flexible than regular wood beams.
- Choosing the right size is based on how much they need to support and how far they need to stretch.
- Advice from beam manufacturers is really important when picking the right size.
- Be mindful of how you install and handle these beams to keep your building safe and strong.
What is Engineered Wood?
Engineered wood is a modern building material. It’s made by bonding wood pieces together. This method produces stronger and more stable materials than the traditional solid wood.
This material is ideal for big projects needing durability. It’s perfect for situations where regular wood might not hold up well.
Types of Engineered Wood Beams
The main types of beams are:
- Laminated veneer lumber (LVL): It’s strong, made by layering thin veneers. They’re glued together.
- Parallel strand lumber (Parallam): Made from parallel, long wood strands bonded together.
- Laminated strand lumber (TimberStrand): Wood strands are layered and glued together. It forms a sturdy product.
Advantages of Engineered Wood Over Traditional Lumber
There are several benefits to using engineered wood over traditional lumber:
- It’s stronger and more rigid than regular lumber in many cases.
- Engineered wood is made with consistent quality, meeting precise standards every time.
- It’s versatile, coming in many sizes and shapes for a variety of building types.
- Using this wood can be better for the environment since it’s made from sustainable sources.
These advantages are making engineered wood more common in building projects. This includes homes and commercial buildings.
Factors Influencing Engineered Wood Beam Size
The size of an engineered wood beam depends on the loads it supports and the distance it spans. Calculating the loads, whether from the roof, floor, or others, is key to proper sizing. The span length needed is also crucial; longer spans require bigger and stronger beam sizes. To ensure safety, building codes and design rules help figure out these aspects.
Load Requirements
Rooftop and floor loads are big factors in deciding beam size. Think about the material’s weight, the number of people, and weather loads, like snow or wind. It’s vital to calculate these accurately. This ensures the beam is strong enough for the job.
Span Length
The beam’s span length is very important in choosing its size and design. Longer spans need bigger beams to stay strong and avoid bending too much. Building codes and norms set guidelines for the longest a beam can be, based on its size, space, and load. Starting with the right span length is critical. It leads to picking the best beam size for a safe and stable building.
Architects, builders, and engineers can design great-looking, safe structures by understanding these beam size factors.

Choosing the right engineered wood beam size is crucial for any building job. To help with this, manufacturers offer detailed span tables and design values. These tables show what loads and spans various beam sizes can support.
They consider the material’s properties, how much the beam can bend without breaking, and how long it will be under pressure. Designers and builders use these tables to find the best beam size for their project quickly.
Span Tables and Design Values
These tables, crucial for sizing engineered wood, are free to use. They include information for spans in feet, like 11’0″ or 12’0″. Normally, the deflection limit is set at L/360.
The American Forest & Paper Association also offers a long table with span suggestions for traditional wood beams up to 32 feet long. This table has 140 pages of data. Using these resources, builders can quickly find the right engineered wood beam size for their needs.
Sizing Process
Finding the correct beam size starts with knowing the weight it must carry and how far it spans. Builders then check the manufacturer’s data to pick the beam that’s strong and rigid enough.
There’s a trick builders can use. Building codes sometimes let them lower the live load, for example, the snow on a roof. Since roofs don’t have full snow all that often, this can mean using a smaller, cheaper beam.
Material properties and beam dimensions are key in choosing the right beam. A stronger LVL, for example, can hold up more weight. Depths of LVL beams range from 7 ¼” to 18″.
The Anthony Power Beam (APB) is made to match common wall sizes, with widths of 3 1/2″ and 5 1/2″. Parallam, which is also known as Parallel Strand Lumber (PSL), offers even more variety. It comes in widths from 1 ¾” to 7″ and depths from 9 ¼” to 18″. Knowing about these different products helps designers choose the best one for their project.
| Engineered Wood Product | Typical Dimensions |
|---|---|
| Laminated Veneer Lumber (LVL) | Depths of 7 ¼” to 18″, Lengths up to 60 feet |
| Anthony Power Beam (APB) | Widths of 3 1/2″ and 5 1/2″ to match 2×4 and 2×6 wall thicknesses |
| Parallam (Parallel Strand Lumber) | Widths from 1 ¾” to 7″, Depths of 9 ¼” to 18″, Lengths up to 60 feet |
With span tables and a good grasp of the sizing process, construction experts can pick the perfect engineered wood beam size with confidence. This careful approach ensures the beam is both structurally sound and cost-effective.
Installation and Handling
Installing and handling engineered wood beams right is so important. It ensures they will work well for a long time. Makers give a lot of advice on how to install them correctly. This includes how to give them the support they need and to join them safely.
Lateral Support Requirements
Engineered wood beams must have support along their sides. This keeps them from bending or becoming unstable.Usually, the frame around them and the outside layer help support them. Putting a brace on the side facing away from the main weight helps keep the beam straight. Adding small walls on the upper part of bigger beams can also make them safer. If these beams don’t have enough support, they could bend. This shows why proper setup is key.
Connection Details
When you connect engineered wood together, you need to follow certain rules. This includes the way you use nails and the parts that will touch each other. It’s important to connect them right when there’s a lot of weight or force on the beams. Beams that only hold weight on one side should get extra support if a similar weight goes on the other side. This is especially true for beams that are wide. If a beam gets pushed on from one side, it might start to turn. The more weight is on its sides and not in the middle, the more this can happen.
Beams that go across long distances need good support to keep them from shifting. If you face any stability issues, sometimes using a single thick beam instead of several thinner ones can help. But, thinking about how you will use the beam and its support is key when choosing which one to use.
“Proper installation and handling of engineered wood beams is crucial for ensuring their long-term performance and structural integrity.”
| Key Installation Considerations | Details |
|---|---|
| Lateral Support | Continuous lateral support along the beam lengthCompression edge bracing to prevent bucklingInstalling pony walls on dropped garage door headers |
