In most conductors, such as metals, the Hall effect is very small because the density of conduction in electrons is very large and the drift speed (charged particle erraticism) is extremely small, even for the highest obtainable current densities.

Dear Pradeep Raja C,

Ideally you should use the four point probe technique to measure sheet metal conductivity.
