# How far can a triple 2×6, 2×8, 2×10, and 2×12 beam span

A triple beam is a type of structural beam. Generally made of timber wood. These are basically made up of three individual beams that are laminated together with an adhesive tightly. This makes it stronger and stiffer as compared to a single beam. Thus; it allows it to span a longer distance. So In this article, we will discuss how far can a triple 2×6, 2×8, 2×10, and 2×12 beam span. If you want to know how far can a double 2×6, 2×8, 2×10, and 2×12 beam span then you can read our previous article.

They are made up of species of wood (southern yellow pine and Douglas fir and are categorized as

Southern yellow pine is the strongest species of wood that has the capability to span more distance when compared to other species of wood. Grade 1 lumber has higher strength as compared to other grade lumber due to fewer knots in it.

HOW a triple 2×6, 2×8, 2×10, 2×12 beam made

1. A triple 2×6 beam made by laminating three 2×6 lumber pieces together.
2. A triple 2×8 beam made by laminating three 2×8 lumber pieces together.
3. A triple 2×10 beam is made by laminating three 2×10 beams together.
4. A triple 2×12 beam is made by laminating three 2×12 beams together.

Triple beam 2×6 beams are versatile and strong materials and thus can be used in a variety of applications. Such as header, beam, rafters, deck beams, pergola beams, and gazebo beams as they are very strong.

Beams are very important as they carry the load and transfer the dead load of the subfloor. The live load of people living in the building beam is thus an essential structural component in construction. For pressure preservative-treated southern pine no 2 grade there is a method for estimating beam spans for any preliminary design.

Now we will look at how far can a triple 2×6, 2×8, 2×10, and 2×12 beam span.

### How far can a triple 2×6 beam span?

Considering the general thumb rules and guidelines. A southern pine 2×6 triple deck beam can span up to a maximum distance of 8 feet for residential applications with a total load of 50 psf (40 psf live load + 10 psf dead load ) with a deflection limit of L/360.

### How far can a triple 2×8 beam span?

Considering the general thumb rules and guidelines. A southern pine 2×8 triple deck beam can span up to a maximum distance of 10 to 12 feet with a total load of  50 psf (40 psf live load + 10 psf dead load ) with a deflection limit of L/360.

### How far can a triple 2×10 beam span?

Considering the general thumb rules and guidelines. A southern pine 2×10 triple deck beam can span up to a maximum distance of 12 to 13 feet with a total load of  50 psf (40 psf live load + 10 psf dead load ) with a deflection limit of L/360.

### How far can a triple 2×12 beam span?

Considering the general thumb rules and guidelines. A southern pine 2×12 triple deck beam can span up to a maximum distance of 15 feet with a total load of  50 psf (40 psf live load + 10 psf dead load ) with a deflection limit of L/360.

#### Conclusion

In this article, we know that the #2-grade southern pine 2×6 triple deck beam can span a maximum up to 8 feet. A 2×8 can span up to a maximum of 10 feet to 12 feet. A 2×10 triple deck beam can span up to 12 to 13 feet . A 2×12 triple deck beam can span up to 15 feet.
