Ply-Lam is an engineered wood product developed primarily for use in the stair building industry. Ply-Lam was designed to be used as stringer material in all types of wood stairs. Ply Lam is used as a replacement for the dimensional lumber (2x10 or 2x12) most commonly used for Construction-Grade stairs and as a “sub-stringer” for Finished-Grade (veneered) stringers.
Pressure treated Ply-Lam is also available for use as stringers in exterior applications.
With Ply-Lam every piece is perfect – No crowns, twists or waned edges. Ply Lam doesn’t warp or crack and large knots are never a problem. See: Benefits
Ply-Lam Manufacturing is now providing stringer material for Stair Builders in Alberta, B.C. and Saskatchewan. See: Applications and our Product Testing page
