What is the maximum span for Southern Pine radius edge decking?
The maximum recommended span for 5/4 radius edge decking (R.E.D.) manufactured from U.S.-grown Southern Pine is 24 inches on center. However, be aware that the maximum recommended span for 5/4 R.E.D. manufactured from imported Southern Pine (stamped I-SP) or Caribbean Pine (I-CARIB) is 16 inches on center.

How long will pressure-treated posts last in the ground?
Pressure-treated wood that has been properly treated and installed for its intended end-use can be expected to last for many decades in ground contact. Ongoing tests sponsored and monitored by the USDA Forest Service, Forest Products Laboratory, confirm this finding. For construction details, see Footings & Posts.
Can I burn treated lumber at the job site? Wood treated with water-borne preservatives must not be burned because combustion breaks the unique bond formed between the preservative solution and the wood. When the bond is broken, the components of the preservative can be released in the form of ash and particulates, which can be harmful if inhaled. It is not a good idea to burn any building product. Best practice is to properly dispose of building products in a permitted municipal
solid waste landfill. For more information, go to Handling Treated Wood.
My client needs wheelchair access. Where can I get information on ramps?
When incorporating Universal Design options such as access ramps, contact your local building official before construction begins to insure compliance with local codes. Visit the Center for Universal Design for more information and also see their publication Wood Ramp Design.
Common types of access from ground level into the raised home include wood ramps, earthen landscaping, platform or stair lifts, and for multi-story homes, elevators. Most common is the wood ramp, usually constructed from pressure-treated wood. Wood ramps are economical and easily adaptable either for new construction or an existing home. Wood ramps can be designed to be hidden from the street, or if visible, can be detailed so that they blend attractively into the architectural style of the home. Universal Design may also include other adaptations such as bathroom fixtures and lowered counters and cabinets.
