Lock-Deck is a structurally engineered product of two to five kiln-dried lumber laminations bonded together with an exterior waterproof adhesive to form glue-laminated decking. The decking is used for ceilings and roofs, as well as for balconies, mezzanines and floors.
Lock-Deck is commonly used in Heavy Timber construction as well as wood frame and hybrid systems.
Lock-Deck is available in specified and random length and long length (finger-jointed) decking, plus a variety of face patterns, textures and finishes.

Species: Douglas Fir/Larch.
Species: Ponderosa Pine.
Species: Western Red Cedar.
Species: Southern Pine.
** NOTE TO SPECIFIER ** Below are available on inquiry.
Species: Alaska Yellow Cedar.
Species: Idaho White Pine.
** NOTE TO SPECIFIER ** First grade below is available in most species, this grade is manufactured with a clear face. This grade may contain occasional small knots or minor characteristics that do not detract from the overall appearance. The grade is the finest in quality and the ultimate in appearance. Supreme is for use where appearance is more important than budget.
** NOTE TO SPECIFIER ** Grade below is available in all species, this grade contains sound knots and natural wood characteristics. Occasional pieces may contain chipped edge knots, short end splits or seasoning checks, and pin holes. The most widely used grade, it is well suited to most applications.
** NOTE TO SPECIFIER ** Grade below is available on inquiry, this rustic grade is recommended for industrial applications where strength is more important than appearance. This grade allows face knotholes, stain, end splits, skip, roller split, planer burn and other non-strength reducing characteristics.
** NOTE TO SPECIFIER ** Delete patterns below not required. Check with manufacturer before specifying any pattern except the Standard Vee.
Pattern: Standard Vee.
Tongue-And Groove Edges: Center laminations shall be offset and machined to form a tongue and groove on both the edges.
** NOTE TO SPECIFIER ** Delete end type not required.
Ends: End matched (tongue-and-groove).
** NOTE TO SPECIFIER ** Lengths 18' to 20' are available on special order. Although the random length continuous layout is the most efficient and cost-effective system, certain structural requirements must be met. Check with manufacturer.
Random Length Continuous Spans: 6' to 16', shipped in multiples of 1 foot and 1 inch short of nominal.
** NOTE TO SPECIFIER ** Simple spans require that specific length(s) of decking be specified and located. It also provides shorter spans for the same thickness decking than the random length layout. Delete below if decking length is not to be included in the specifications.
Decking Length A: ________
Decking Length B: ________
Decking Length C: ________
** NOTE TO SPECIFIER ** Delete sizes not required, indicate locations if known. Note that thickness should be based on load tables or be selected by a structural engineer. Lock-Deck(TM) can be engineered to carry diaphragm shear forces from earthquake and high-wind forces. Consult manufacturer's recommended details. Such designs must have a continuous Chord along all sides to resist the moment forces.
** NOTE TO SPECIFIER ** Not all surfaces are available on all species. Check with manufacturer before specifying Wire Brushed surface.
Surface Texture: Smooth Surfaced.
Surface Texture: Smooth Sanded.
Surface Texture: Coarse Sanded (16 grit).
Surface Texture: Resawn (crossband saw texture).
