Notes:
1. 	Spans are the overall length of a simple span. Up to a 2' cantilever can be added to the overall length atone end.
2. End bearing length must be at least 1.5".
3. Cantilever bearing length must be at least 3".
4. Joists require support across their full thickness or width.
5. Joist tables are based upon 100% duration of load.
6. Use the Exacte by PWT software for conditions outside the scope of this guide.
7. Lateral bracing for the compression edge must be provided.
8. Provide support to prevent lateral movement and rotation at the bearings.
9. 	The spans for Pressure Treated Dimension Lumber are provided as a reference only. Do not use thesespans for specification or design.

Notes:
1. Beams spans are defined as overall length, simple spans only.
2. Bearing length must be at least 3.5".
3. Beams require support across their full thickness or width.
4. Beam spans are based upon 100% duration of load.
5. Use the Exacte by PWT software for conditions outside the scope of this guide.
6. Lateral bracing for the compression edge must be provided.
7. Provide support to prevent lateral movement and rotation at the bearings.

Design Assumptions:1. 	Stringer run refers to the horizontal projection of the stairs.
2. 	Table values are based on a maximum step rise of 7¾'' and a minimum step run of 10''. Consult local
building codes for restrictions on riser and tread dimensions.
3. 	Table values are limited by deflection equal to L/360 at live load or L/240 at total load.
4. 	Stringer runs are based on 100% duration of load.
5.	Verify compliance with the local building code.
6.	For stringers not covered by these tables consult with the design professional.
7. 	These spans are for dry use conditions only.
8. 	Stringers shall be separated from concrete or masonry with 1" stand-off.
9. 	Spans have been limited by the capacity of framing anchors at the stringer to header connection
listed below.		 One (1) Simpson® A35 framing anchor for stringers supporting the ends of the tread.		 Two (2) Simpson® A35 framing anchors for stringers supporting the middle or center of the tread.

One of our customers
recommended PWT Treated
for a deck-build project,
and we discovered thisproduct was available
nationwide! One ofmany unique qualities
about PWT Treated isthat you can get theboards cut to length—premade to the size
you need. And it comeswith a 25-year warranty.
That’s a huge benefit!
