One part of my shop is 32X40 w/ W22X14 inch beam running the 40ft long w/ a 3.5x3.5x1/4 wall sq. tube. as a centered column.There is a second floor of 32x40 above for storeage. which has roughly 60#lbs. per sq. ft.load bearing wt. The engineer I hired when I built the shop said to build the shop w/o the centered column I would need a W42x24 inch beam. ( W42 means 42 pounds per running foot. 24 means 24 inches tall. you will need something of this size to carry that type of load. The engineer charge me $300.00 to size my beam after he looked over my floor plan drawing. Some large steel fabricating frims have engineers on staff that can do the math for you. Good luck.Scott.
