The biggest problem is "cost effective" that is only going to be steel, stainless, aluminum and titaninum would all work but cost will be 2-3x more +.
Your best option is sticking with steel, 250 lbs is not that much of a load and would handle it just fine with a good welder. If you need any further assistance just let me know.
