Concrete Form Panels
Formwork represents close to half the cost of a concrete structure. Form development, therefore, warrants serious and detailed engineering consideration. The realization of architectural intent, similarly, is related to formwork quality. The form is to structure what a mold is to sculpture, and it follows that a concrete building or other structure will be as aesthetically true as the form that shapes it.
This section of the website and the affiliated APA publication, APA Design/Construction Guide: Concrete Forming, Form V345, is intended for use by architects, engineers and contractors in their pursuit of successful, cost-effective concrete structures. It contains APA panel grade information, form maintenance recommendations, design data and several project case studies.

Look For the Mark of Quality
Always insist on engineered wood products bearing the mark of quality – the APA trademark. Your APA engineered wood purchase is not only your highest possible assurance of product quality, but an investment in the many trade services that APA provides on your behalf. The Association’s trademark appears only on products manufactured by member mills and is the manufacturer’s assurance that the product conforms to the standard shown on the trademark.
For concrete form panels, those standards include Voluntary Product Standard PS 1-09 - Structural Plywood and Voluntary Product Standard PS 2-10 - Performance Standard for Wood-Based Structural-Use Panels. Panel quality of all APA trademarked products is subject to verification through APA audit.
The APA trademark appears only on engineered wood products manufactured by members of APA. The mark signifies that the manufacturer is committed to a rigorous program of quality verification and testing and that products are manufactured in conformance with an APA or national standard. A list of APA members that manufacture concrete form products is provided below.
Many imported and off-grade panels never undergo product qualification testing and may not meet the strict criteria necessary for the intended application. APA completed tests on six batches of Asian overlaid plywood intended for use in the concrete forming industry. These panels were sampled from five different areas of the U.S. Even with this small sample size, the testing demonstrated the wide range of variability of non-certified, imported products sold for concrete forming. Without a credible certification mark showing conformity to a standard, the end-user has no assurance of good panel performance. View the report.
