What Size Beam for a 30 Foot Span

When it comes to choosing the right size beam for a 30 foot span, there are a few things to consider. The first is the weight of the load that will be placed on the beam. The second is the type of material the beam will be made from.

And lastly, the span itself. With all of these factors in mind, it’s important to consult with a professional before making any decisions.

There are a few things to consider when choosing a beam for a 30 foot span. The first is the weight that the beam will need to support. If the beam will be supporting a lot of weight, you will need to choose a stronger beam.

The second thing to consider is the type of material the beam will be made out of. Stronger materials like steel or concrete will be able to support more weight than weaker materials like wood. Finally, you will need to decide how the beam will be supported.

Beams can either be supported by columns or they can be free-standing. If you are looking for a strong and durable beam for your 30 foot span, steel would be a good choice. Steel beams are very strong and can support heavy weights.

They are also quite easy to find and relatively inexpensive. Another option would be concrete beams. Concrete beams are even stronger than steel beams and can also support very heavy loads.

However, they can be more difficult to find and may cost more money than steel beams.

What Size Steel Beam Do I Need for a 30 Foot Span?

When it comes to designing a steel beam for a 30 foot span, there are various factors that need to be considered in order to determine the most suitable size. These include the type of load that will be placed on the beam, the distribution of that load, and the environment in which the beam will be located. In general, however, a minimum depth of 18 inches is required for a 30 foot span steel beam.

Can a Wood Beam Span 30 Feet?

There are many variables to consider when it comes to determining how far a wood beam can span. The type of wood, the size and weight of the beam, and the load being placed on the beam all play a role in how much weight the beam can support and how far it can span. For example, a 2×4 made of Douglas fir can safely span about 6-8 feet, while a 4×4 made of hemlock can span up to 12 feet.

If you’re looking at spans longer than that, you’ll need to use larger beams made from stronger woods like oak or cedar. And if you’re planning on putting a heavy load on your beam – like a hot tub or an addition to your home – you’ll need to factor that into your calculations as well. In general, though, most wood beams can span somewhere between 20-40 feet depending on the factors mentioned above.

So if you’re planning on using a wood beam to span 30 feet, it’s definitely possible – just be sure to do your research and pick the right kind of wood for the job!

How Much is a 30 Foot Support Beam?

The cost of a 30 foot support beam can vary depending on the type of material used and the company supplying it. However, on average, you can expect to pay between $600 and $1,200 for this size of beam.

What Size Beam Do I Need to Span 32 Feet?

When it comes to finding the right beam size to span 32 feet, there are a few things you’ll need to take into consideration. The first is the type of material the beam will be made out of. Steel beams are going to be your best bet for spanning long distances, but wooden beams can also work if they’re properly supported.

The next thing to think about is the weight that will be placed on the beam. If you’re planning on using it for construction purposes, then you’ll need to factor in the weight of the materials that will be placed on top of it. Finally, you’ll need to consider the wind load and snow load that could potentially affect the structure.

Once you have all of this information, you can start to look at different beam options that would work for your specific situation. For example, a steel I-beam with a W8x18 designation would be able to support up to 4,500 pounds per linear foot when used in construction applications. This means that it could easily span 32 feet without any issues.

However, if you’re looking for something a bit cheaper, then a wooden beam might be a better option. Just make sure that it’s properly reinforced so that it can handle whatever weight or weather conditions are thrown its way.

What Size Beam for 32 Foot Span

If you’re planning to build a 32 foot long beam, you’ll need to choose the right size lumber. The most important factor in choosing the right size lumber is the strength of the beam. The stronger the beam, the more weight it can support.

The next factor to consider is the type of load that will be placed on the beam. If you’re planning to use the beam for a heavy load, like a garage or workshop, then you’ll need to choose a stronger beam. If you’re only using it for light loads, like a deck or porch, then you can choose a lighterbeam.

Once you’ve considered the strength and type of load, you can select the appropriate size lumber for your project. For example, if you’re building a small shed with light loads, 2x4s may be sufficient. But if you’re building a large garage with heavy loads, then 2x6s or larger would be better suited for your needs.

When in doubt, it’s always best to err on the side of caution and choose a stronger beam than what you think you need. It’s always easier to remove excess lumber than it is to add more later on!


If you’re planning to build a beam that spans 30 feet, you’ll need to use a bigger beam than you would for a shorter span. The exact size will depend on the weight that the beam needs to support and the type of wood that you’re using. For example, a common lumber beam span chart shows that 2x8s can span up to 12 feet when used as floor joists.

But if you’re using those same 2x8s as roof rafters, they can only span up to 8 feet. So, if your 30-foot span is for a roof, you’ll need at least 3 2x8s side-by-side.
