All APA Plyform concrete form panels are Exterior classification, and are available in three classes denoting their strengths, Class I or Class II and Structural 1.  They can be ordered with specific faces and back veneer grades.

The three types of Plyform panels are:

  • B-B and B-C Plyform
  • HDO Plyform
  • MDO Plyform

APA’s standard, sanded exterior B-C grade plywood panels are also suitable for concrete forming when one smooth, solid face is required.
