what is steel made from?
Iron, carbon, and other elements
What separates steel from cast iron?
They differ in corrosion resistance. cast iron can suffer worse from corrosion compared to steel, and is often not used in high rise construction compared to steel. Cast Iron is also less ductile
At What point in history did steel construction really start to take form
19th century
What is the main benefit of steel construction compared to wood and concrete.
Steel construction can allow for thinner and taller structures given it’s high strength properties. It also allows for greater artistic expression from an architect.

“Eiffel Tower” and “Crystal Palace”
How do we make steel fire resistant?

corrosion
What type of steel is best for facades?
weathering steel
What’s special about stainless steel?
resistant to rusting/damage
