This document provides a table showing the maximum spans in meters for a 6mm check plate under different live load (LL) conditions and whether the plate is unstiffened or stiffened. The spans range from 0.85m to 3.65m as the live load increases from 150kg to 500kg. Any cells marked as NA indicate the plate could not support that live load if unstiffened. The table is based on a safe deflection limit of L/300 according to the Egyptian building code.
