Why was it better to build skyscrapers with steel instead of iron?

Answer 1

Because steel has a high cost/strength density. In other words, its cheap to use when you take into account that you don't have to use as much of it. And steel has many favorable properties, unlike wood, steel will normally give some indication that it is going to fail (crack, deformation, etc.) where as wood will just break. This is good because it gives you a chance to fix the problem before it becomes life threatening.

Answer 2

Alloy beams can be designed to be :

• stiffer
  
• stronger
  
• lighter
  
• less apt to corrode
  
• better in fire exposure
  

Answer 3

Steel is stronger and lighter than iron, allowing for taller and more stable structures. Steel is also more resistant to corrosion and fire than iron, making it a safer and more durable material for building skyscrapers.

Answer 4

Steel alloy beams are stronger and lighter that regular Iron beams and that allows for building to be build taller, bigger and with less raw material.

Answer 5

Alloys are engineered to be lighter, stronger, and more resilient.

Answer 6

because it is a strong metal
