Usually made of clay, brick has been used in many ancient structures, like the Roman aqueducts, the Pantheon and the Great Wall of China. The Sumerians made the earliest recorded bricks, and we can deduce that those early bricks used in construction were crude, uneven, sun-dried blocks probably made of silt that was deposited when high waters receded after storms [source:Britannica].
Chinese vs American Steel Quality:Building Comparisons A good example of Chinese steel quality issues leading to potential danger is the Oakland Bay Bridge in San Francisco, California. The lower quality of the foreign steel was discovered in 2013 when a seismic test led to the discovery of 32 faulty rods that had to be replaced; they had been corroding in a
The main bridge structure has a series of steel arches and catenaries, or inverted arches, linked together and resting on concrete pylons. These towers, the highest reaches 38m, settle between waves at the point where the shape of the surface allows the self-intersection and narrows into a single beam.

Strength  Yield strengtYield strength is the most common property that the designer will need as it is the basis used for most of the rules given in design codes.In European Standards for structural carbon steels (including weathering steel), the primary designation relates to the yield strength, e.g. S355 steel is a structural steel with a specified minimum yield strength of 355 N/mm².

The United States structural steel industry has the capacity to produce 6 million tons of structural steel per year. In 2004, our usage was about 4 million tons of wide-flange structural product, which means there is certainly adequate capacity to meet any growth in the foreseeable future. Structural steel is readily available. 4.Bridges - SteelConstructionfoLonger spans of 100 to 200m typically use either a single box or a pair of boxes with crossbeams. For such long spans and for bridges such as lifting bridges, where minimising structural weight is very important, an all-steel orthotropic deck may be used instead of a reinforced concrete slab.
