The weight-bearing capacity of 7/16" (11 mm) OSB (oriented strand board) when standing on edge can vary depending on several factors, including the span or distance between supports, the type and quality of the OSB, and the load distribution.
As a general guideline, 7/16" OSB is commonly used as sheathing material in construction and is not typically designed to support heavy loads on its own. However, it can contribute to the overall structural strength of a building when properly installed and supported.
For specific weight-bearing calculations, it is recommended to consult the manufacturer's technical specifications or engineering guidelines for the particular brand and grade of OSB you are using. These specifications will provide more accurate information regarding load capacities, including maximum span distances and load ratings for different applications.
If you have a specific scenario or load requirement in mind, it is best to consult with a structural engineer or building professional who can evaluate the specific factors involved and provide a reliable recommendation based on local building codes and regulations.
