What is the Load capacity of a 4 inch slab floor?

The load capacity of a 4-inch slab floor can vary based on factors such as the type of concrete mix, reinforcement, and design specifications. Typically, a standard 4-inch reinforced concrete slab can support a live load of approximately 40 pounds per square foot (psf) for residential applications. However, for commercial or industrial use, the load capacity may be higher, often ranging from 50 to 100 psf or more. It's essential to consult structural engineering guidelines or a professional to determine the specific load capacity for a given application.
