High Density Overlay (HDO) PlyformHigh Density Overlay (HDO) Plyform concrete forming panelsThis Plyform panel meets the same general specifications as Plyform Structural I or Class I. All classes of HDO Plyform have a hard, semi-opaque surface of thermosetting phenolic resin-impregnated material that forms a durable, continuous bond with the plywood. During plywood production, these overlays are bonded to the plywood …

B-B and B-C Plyform Concrete Form PanelsB-B and B-C Plyform Concrete Form PanelsNonoverlaid Plyform is usually made with B grade veneer face and B or C grade veneer back and referred to as “B-B Plyform” or “B-C Plyform.” These panels are available as Structural I or Class I. The panels are sanded on both sides and treated with a release …

What is Structural Composite Lumber?Structural Composite Lumber (SCL)Structural composite lumber (SCL) is a family of engineered wood products created by layering dried and graded wood veneers, strands or flakes with moisture-resistant adhesive into blocks of material known as billets, which are subsequently resawn into specified sizes. SCL includes laminated veneer lumber (LVL), parallel strand lumber (PSL), laminated strand lumber (LSL) …

Strength & Stiffness Plywood and OSB structural panels possess inherent strength and stiffness. They resist bending or deflection, racking or shape distortion and impact damage. Because of their split resistance, wood structural panels possess excellent fastener-holding properties and can be nailed very near panel edges. For most applications, stiffness is one of the biggest benefits of wood structural panels. Excellent …

The PI Laboratory has maintained a continuing interest in the development of satisfactory test methods for determining shear characteristics of wood, plywood, adhesives, and more recently sandwich constructions. The anisotropic structure of wood has added to the difficulty of developing test methods that reliably evaluate the desired properties. This paper presents a brief description of the test methods used, traces …
