Steel plates in the Philippines, like in the rest of the world, are sheets of metal available in flat sheets or coiled strips, made by rolling metal into flat pieces. Steel is made into other kinds of shapes used for construction, but what is steel, what is it made of, and how important is it to construction?
The Philippines is a developing country that is in need of a major change. The Philippines has been doing very well in the world economy due thanks to the magnificent efforts of the BPO and IT industries in the country. There is a need, however, for construction of public infrastructures to catch up with the rapid development of the country’s economy. Construction in the country for government projects such as road work and the building of bridges and public infrastructure takes months to complete.
In its most basic composition, steel is an alloy which is a mixture of metals and other elements, mostly of iron and carbon. Steel is a very versatile material that is widely used across a large spectrum of industries since steel is considered the most durable, reliable material in terms of tensile strength while still keeping its production cost at a minimum. Steel in particular is made of iron combined with manganese, chromium, nickel, and tungsten, and usually made of iron and carbon. Carbon makes up about 2.1% of the weight of the steel, and if the steel has more than 2.1% of its weight in carbon, it’s no longer called just steel.
To make steel, iron ore must first be mined. It is then smelted. Smelting is the process of extracting the metal from an ore. When the iron is put in a furnace to be smelted, the impurities in the ore is removed, the metal is extracted, and carbon is added.
