steel

The bridge is reinforced with huge steel girders.

On the other hand were purely utilitarian structures, such as factories and grain elevators, which employed modern materials such as steel girders and plate glass in an undisguised and unadorned manner.

For example, glass could be used to open up walls and eliminate their stone and brick masonry because large spaces could now be spanned with steel beams.

For example, in traditional architecture, stone or brick walls served a structural role, but in a steel-beam building the walls were essentially hung from the internal skeleton of steel beams, which meant that walls and corners no longer needed to be solid but could be opened up in unexpected ways.

Similarly, steel beams could be used to construct balconies that projected out from the building without any support beneath them.

Steel construction, on the other hand, can support a building of 50 or 100 stories without difficulty.

A structure built with steel beams protected by terra-cotta tiles was still three times lighter than a comparably sized building that used masonry construction, so the weight of the tiles was not a problem.

In the case of the steel industry, this means the mining of iron ore, the transportation used to get ore from the mine to the mill, turning the ore into the steel, the manufacturing process and sales.

He practiced Vertical Integration on such a large scale that he practically owned the whole steel industry.

In 1837, however, John Deere patented a sharp-cutting steel plow that sliced through the sod without soil sticking to the blade.

And that led to the lap guitar, which is also called the steel guitar because the player slides a steel rod up and down the neck.

So let’s get back to when the steel guitar was first introduced in the United States.

Uh, Hawaiian music was based on the steel guitar I just described.

Some sailors learned how to play the steel guitar and brought it home to the States.

Anyway, by the 1920s, with the advent of the public dance movement, people were gathering in large groups to listen to steel guitar music.

So you could actually draw out a 36,000-kilometer strand or ribbon of nanotubes stronger than steel, but maybe a thousandth the thickness of a human hair.

Iron manufacturers, which had starved for fuel while depending on charcoal, also benefited from ever-increasing supplies of coal: blast furnaces with steam-powered bellows turned out more iron and steel for the new machinery.

In fact, by the early 1940’s, even though steel cables were available, most ships in the United States Navy were not moored with steel cables; they were moored with Manila hemp ropes.

Well, the main reason was that steel cables degrade very, very quickly in contact with salt water.

And it’s red because of the zinc paint that goes on those stainless steel cables.

That, if they start at one end of the bridge and they work to the other end, by the time they finish, it’s already time to go back and start painting the beginning of the bridge again, because the bridge was built with steel cables, and steel cables can’t take the salt air unless they’re treated repeatedly with a zinc-based paint.

Steel used to be important in South Wales.

As she waited, she steeled herself for disappointment.
