What do you use to cut composite decking?
How to Cut & Fasten Composite Decking. You can make simple cross cuts in composite decking the same way you would cut any soft pine—a power circular saw will work fine. A power miter saw can provide very accurate, straight cuts, and a table saw with support extensions can make all types of cutting easier.

Does Trex decking need to be spaced?
You must gap Trex® decking, both end-to-end and width-to-width. Gapping is necessary for drainage and the slight thermal expansion and contraction of Trex decking boards. Gapping also allows for the shrinkage of the wood joist system.
What is the spacing on Trex decking?
Most composite and PVC decking brands, like Trex and Azek, recommend a maximum joist spacing of 16 inches OC.
What is the maximum span for Trex decking?
Trex Signature railing and Rod Rail are made to be installed at maximum 6′ or 8′ CLEAR SPAN BETWEEN POSTS. » Determine post locations prior to installing any decking.
Why is my composite deck warping?
The reason why most composites warp is due to thermal expansion. When plastic fibres of the composites get heated, it will expand. It will return to its original size unless there’s a problem with the decking board spacing. So when installing decks, you will want to space your decks enough for the boards to breath.
What are the problems with composite decking?
Composite Decking Problems
- Moisture-resistance doesn’t stop mold. Composite decking is often sold as a close to a waterproof material as you can get.
- Warping and weakening isn’t uncommon.
- Staining and color fading leads to frustration.
- Easily scratched surface can’t be fixed.
- Composite’s characteristics limit usability.
Are 2×6 strong enough for deck joists?
2×6 joists should only be used on ground-level decks that do not require, and will not provide for, any guards. Most decking is not strong enough to support longer spans than 16″. Some builders reduce joist spacing to 12″ on center to strengthen the deck frame or to increase maximum allowable joist spans.
How far can a 2×6 decking span without support?
A decking board made up of 2x6s can span a maximum distance of 24 inches from joist to joist.
How far can a 2×6 span without support?
About 13 feet at 16 in spacing.
How far can a 2×8 joist span without support?
A rule of thumb is 1.5 times a joist’s depth but in feet when spaced at 16” centers. In general, a 2×8 will span 1.5 x 8, so 12-feet.
How much weight will a 2×8 joist hold?
For a 2 x 8 joist and a double layer of 3/4″ something (plywood/osb; a single layer will probably be too thin to support heavy equipment) you’re looking at something on the order of 15 pounds per square foot (psf) minimum for joists at 16″ centers.
How far can a triple 2×10 beam span without support?
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 far can a 2×8 overhang?
Deck Joist Cantilever Rules and Limits
| Joist Spacing (o.c.) | 24″ | |
|---|---|---|
| Species | Size | Allowable Overhang |
| Southern Pine | 2×6 | 1′-4″ |
| 2×8 | 2′-4″ | |
| 2×10 | 2′-10″ |
How far can a double 2×8 cantilever?
According to the new span tables and IRC provisions, cantilevers can extend up to one-fourth the backspan of the joist. This means that joists, such as southern pine 2x10s at 16 inches on-center, spanning 12 feet are allowed to cantilever up to an additional 3 feet (see illustration, below).
