The gauge and length of galvanized construction staples recommended for attaching plywood depend on the thickness of the plywood and the specific application. Here are some general guidelines to consider:
Gauge:
The gauge of the staple refers to the thickness of the wire used to make the staple. For plywood attachment, staples with a gauge ranging from 16 to 18 are commonly used. Thicker gauges provide increased holding power and are suitable for denser or thicker plywood.
Length:
The length of the staple should be sufficient to penetrate through the plywood and secure it firmly to the substrate. As a general rule, the staple length should be approximately three times the thickness of the plywood. For example, if you are working with 3/4-inch (19 mm) plywood, a staple length of around 2.25 inches (57 mm) would be appropriate.
It’s important to note that the specific requirements may vary depending on the project, the type of plywood, and the substrate being attached. Thicker plywood or certain construction applications may require longer or thicker staples for optimal performance.
Additionally, it’s advisable to consult the manufacturer’s recommendations for the stapler you are using as it may have specific guidelines regarding the compatible staple sizes and lengths.
When attaching plywood, ensure that the 18 gauge narrow crown stainless steel staples are driven uniformly and spaced appropriately to provide sufficient holding power. Consider factors such as the intended load or stress on the plywood and consult with a construction professional or building code requirements for specific recommendations based on your project’s needs.
