In general, small diameter screw piles (less than 3 inches) can typically support loads ranging from 2 to 4 tons per pile. Larger diameter screw piles (greater than 5 inches) can support significantly more weight, with some able to hold up to 100 tons or more.
However, it's important to note that these are just rough estimates, and the actual weight-bearing capacity of a screw pile will depend on the specific circumstances of its installation and use. It's always best to consult with a professional engineer or contractor who can assess your specific needs and recommend the appropriate screw pile solution for your project.
