The Crown HDO Hardwood brand has had proven success for decades and is ideal for applications that require a smoother surface and higher panel reusability than traditional Douglas fir concrete form HDO.

Features & Benefits

Crown HDO Hardwood is constructed with high strength hardwood face and back veneer and Douglas fir inner plies.  The high resin content HDO is applied in a one-step process.  All adhesives used are fully waterproof phenolic resins that meet APA exterior glue bond standards.

Available in 48” x 96” and 24” x 96” in 1/2” to 1-1/8” thickness

  • APA Certified Panel
    Crown HDO Hardwood panels are engineered to be Struc-1 equivalent and meet or exceed APA’s PS 1-09 for HDO Concrete form.

  • Crown HDO Weights
    Crown HDO can be specified as either one or two sided panels with 100 or 120 weight pouring faces, and 30, 100 or 120 weight backs to meet your job site requirements.

  • Hardwood Face and Back
    A durable hardwood veneer is used for the face and back providing a smoother pouring surface and a more durable panel than traditional softwood panels.

  • Two Piece Inner Plies
    Our two piece, Douglas fir inner ply construction method is engineered to provide a more solid panel that can better stand up to job site wear and tear.

  • Multi-Layer Edge Protection
    For additional protection against moisture, all Crown HDO panels are edge puttied and then thoroughly coated with a silver, aluminized, resin-rich alkyd edge seal.

  • Factory-Applied Release Agent
    For safety reasons, HDO panels do not come factory coated with release agent.  Prior to each use, Crown HDO requires application of Nox-Crete or equivalent release agent.
