Treated Lumber Applications
Ground Contact (UC4A)
ProWood Ground Contact is our most widely used, general purpose pressure-treated lumber. It can be used for above ground, on the ground, in the ground, and for freshwater application. Primary uses are areas that will experience frequent or prolonged moisture and for items critical to the integrity of the structure such as beams, joists, and stringers. Backed by a lifetime-limited warranty.
Above Ground (UC3B)
ProWood Above Ground is best suited for areas that are at least six inches above ground and are easily replaced or maintained, such as railings and balusters. Not suitable for deck joists or near ground uses. Backed by a lifetime-limited warranty.
Light Duty
ProWood Light Duty is not for structural uses and does not conform to AWPA/ESR standards. This can be used for split rail fencing, lattice and landscape timbers. It carries a 1-year limited warranty.
Critical Structure (UC4B)
For the toughest jobs, ProWood Critical Structure gets the call. It’s made to withstand the harshest conditions and can be used for critical structure, ground contact, and saltwater splash applications. The go-to choice for supporting permanent structures. Backed by a lifetime-limited warranty.
