ACX Plywood: The Ultimate Resource 2024

“ACX” stands for “A” grade front face, “C” grade back face, and “X” for exterior glue. ACX plywood earns high regard for its ability to provide a high-quality appearance on one side (A) while offering a rougher finish on the other (C). Builders and woodworkers often choose it for projects demanding both aesthetics and durability.

Origins of ACX Plywood

In the mid-20th century, there was a growing need for high-quality plywood that could withstand exterior applications. This demand prompted manufacturers to make a specialized grade known as ACX plywood. They established precise standards to ensure its exceptional quality and durability, setting it apart from other plywood grades.

How is ACX Plywood Made?

Manufacturers bond multiple layers of wood veneers together using high-quality adhesive, typically employing softwood species like pine or fir. An exterior-grade adhesive ensures it can withstand outdoor conditions. These features make it durable and strong, ideal for a range of applications in construction and carpentry.

Grading System

The “A” grade has a high-quality appearance, making it an ideal choice for visible surfaces, while the “C” grade may have more blemishes but maintains structural integrity. “X” grade adhesive is used to stick the boards together. This combination allows for strong and durable plywood which has a good aesthetic.
