What is the maximum span without edge support for 15/32-inch wood structural panels with a span rating of 32/16?

The maximum span without edge support for 15/32-inch wood structural panels with a span rating of 32/16 is indeed 28 inches. The span rating of a panel indicates its suitability for specific applications with respect to the load-carrying capacity when used as either roof sheathing or floor sheathing.

In this context, the first number in the span rating, which is 32, refers to the maximum spacing between supports when the panel is used under a roofing application. This means the panel can be used where the supports are up to 32 inches apart. However, since it also has a second number of 16, indicating the maximum allowed spacing for a floor, we can deduce that this specific size and rating provide flexibility in terms of how and where the panels can be employed.

When we look specifically at the edge support, 28 inches is the threshold that indicates that this panel can be safely used without additional edge support for structural integrity, accommodating typical load conditions up to that span. The edges of the panels must be adequately supported within this limit to ensure that they perform effectively without sagging or experiencing potential failure under load.
