the material used is called sandpaper

Mostly steel. And since welding was new at the time it was held together by rivets made of iron and steel.
depends on who makes them, however most are made from alloyed steel. It is made from carbon steel or from high speed steel, a costlier but better option. The frames are usually of steel, sometimes plastics are used on cheaper versions. The blades, as stated are HSS., with a variable number of teeth per inch depending on its use.
They are generally made of grade 8, heat treated steel.
yes if that steel can carry charge w/o any lose in its capacity due to day light changes.
Most likely, steel. If you put a magnet near one it will be attracted. If one gets wet, it will probably form a coating of rust on its surface.
Steel Girders
They are not. Steel girders can be used because of their strength and are easily manufactured
It allows the girders to be lighter. If you took a solid piece of steel in a square shape and exposed it to stressed, you would discover that the stress in the metal is on the top face and the bottom face. The middle sections do not add to the structural strength of the beam, they simply add weight.
* Tools * Wires * Rails for trains * Girders for making buildings * Hulls of ships * Body of cars and trains * Major appliances * Cutlery and knives * Rulers
Mainly steel girders, rivets, and reinforced concrete.
The invention of steel skeletons and elevators made building skyscrapers possible
It probably would be. It would take an extremely strong tornado to destroy such a structure.

You can start by riveting these two pieces of steel together
yes it did

The statue itself is bronze, and it's internal superstructure ("skeleton") was refurbished just a few years ago with stainless steel girders to replace the original, rusting steel ones.
