A steel plate with a thickness of three-sixteenths of an inch weighs 7.65 pounds per square foot. Steel plate sheets with this thickness typically measure 10 feet wide by 40 feet long and weigh 3,060 pounds, or 1.53 short tons.
Steel plate sheets with a thickness of 10 inches weigh 408 pounds per square foot. Calculations show that this 10-inch thick, 10-foot wide and 40-foot long sheet weighs 163,200 pounds, or 81.6 short tons.
Commonly used in building construction, steel-plate sheets fill in the space between framing walls. These steel-plated walls add increased safety, durability, strength and stability to the overall structure.
