When it comes to engineered wood products, certification isn’t a bonus. It’s essential. That’s why every AcuJoist I-Joist is manufactured under the guidelines of the APA – The Engineered Wood Association.

APA certification ensures our products meet strict structural and performance standards through independent third-party auditing. Our joists are tested and verified under APA’s PRI-400 and PRI-405 programs, which define the properties, quality control, and design parameters for I-Joists used in residential and commercial construction.

For specifiers and engineers, APA-rated joists offer assurance that the published span tables, load capacities, and design values are backed by a recognized standard, not just internal testing. This makes code approval faster and ensures consistency across projects, jurisdictions, and climates.

For distributors, APA certification signals quality and dependability. It allows you to offer your customers a product that is both easy to specify and trusted across the building industry. It also means our manufacturing processes are routinely audited to maintain those standards. You don’t just get consistency today, but on every order moving forward.

At AcuJoist, we don’t just meet industry expectations. We help define them. APA certification is our commitment to building products that perform to the highest level, with integrity you can count on in every bundle.
