Decking Profiles

A profile is the overall shape of a board when viewed from the end. It affects both the installation method and final appearance. Any profile can be combined with any edge bevel.

ProfileDescription
Standard (S4S)
A basic rectangular board. It is fastened by driving screws through the face. Wood plugs are often used to hide the screw heads.
Pregrooved
Grooved along one or both edges for use with hidden fastener systems. No screws show in the finished project.
Tongue & Groove (T&G)
A tongue on one edge and a groove on the other. The tongue of one board fits into the groove of the one next to it. Fasteners (nails or screws) are inserted through the tongues, so they are hidden in the finished project.
Shiplap
An overhang on one edge of the board that overlaps a recessed area on the board next to it. One fastener is driven through underneath this overlap, so it is hidden from view, but another fastener must be inserted above the overlap through the visible face of the board. The visible screw heads are often hidden with wood plugs.
Rainscreen
A combination of pregrooved and shiplap. An overhang on one edge of the board overlaps a recessed area on the board next to it. Edges are grooved for use with hidden fasteners, so no screws show in the finished project.
End-Matched Boards are milled along all four edges instead of just the two long edges. This has a distinctive aesthetic effect, but also a practical one: end joints don’t have to land on a framing member (joist or furring strip), which results in fewer cuts, less wasted material, and a faster install.
Deck Tile
Prefabricated, modular tiles that don’t require framing.

An edge bevel is a contour milled onto the edge of the board. It only affects the final appearance of the project, not the installation method. Any edge bevel can be combined with any profile.

Edge BevelDescription
Square Edge Boards fit together snugly with no bevel, creating a smooth surface.
Nickel Gap Boards edges have a rectangular bevel, which creates a narrow space at the joint, resulting in an aesthetic shadow line.
V-Groove Boards edges have an angled bevel, which creates a V-shaped channel at the joint.
