How low can I go? Light gauge sheet What thickness of steel sheet do I need to achieve a given strength?

I have a customer that originally bought 0.0351" thick sheet steel, CSA grade, G90 zinc coating. They moved to 0.0236" Grade80, G90 to cut costs. The thinner, harder steel satisfied their customer's strength requirements. Their customer would now like a heavier zinc coating (G110) for corrosion protection but our customer wants to keep the total metal thickness the same meaning the base metal thickness will need to decrease. Strength is determined by the base metal thickness, not the zinc coating! What is the formula to determine how thin I can go and stay within the strength requirements of my customer's customer?

Now- Here is where you are going to beat me up. I do not know the strength requirements yet of my customer's customer. If I assume that requirement to be 'x', I could still calculate strength. Thank you very much for your time.
