A 2×10 beam – made up of two 2x10s nailed together – can span up to 11′ without support beneath a deck that is 4′ wide. For a more normal-sized deck, the same beam can span 8′, supporting a deck that is 8′ wide. You can also triple a 2×10 beam.
How Long Can a Beam Be Without Support?
When it comes to construction, beams are one of the most important components. They provide structural support and are used to create strong foundations for buildings and other structures.
But how long can a beam be without support? This is an important question to consider when planning and constructing any building.
The length of a beam without support depends on a variety of factors, including the material used to construct the beam, its thickness, the amount of weight it must bear, and the type of support it will be receiving.
Generally, a beam made of wood or steel can span up to 10 feet without any additional support. However, this length can vary depending on the other factors.
For example, if the beam is made of steel, it can span up to 15 feet without additional support. When planning the construction of a building or other structure, the length of the beam without support must be taken into consideration.
If the beam is too long, it may not be able to support the weight of the structure and may cause the building to collapse.
For this reason, it is important to ensure that the beam is the proper length for the structure and that it is properly supported. The type of support that a beam will receive also affects how long it can span without
