The Crown HDO brand has had proven success for over 40 years and is ideal for applications that require higher panel reusability than a traditional Concrete Form MDO.

Features & Benefits

Crown HDO is constructed with high strength Douglas fir veneer.  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 panels are APA certified Struc-1 and meet or exceed APA’s Product Standard 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 Options
    Crown HDO panels are also available with hardwood faces and backs.  This provides a smoother pouring face and 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.
