$this->bbcode_second_pass_quote('nocar', 'A')ll that iron, and other metals. I want to know where is goes.
How much is to cars and trucks? How much is for highways? (I believe there is lots of iron for reinforcement i highway bridges)
How much is for building public transport?
How much for agriculture equipment?
How much is for bicycles?
How much is for building? Single family housing, apartments, schools, retail, industries?
Almost all iron goes into making steel. Here's where the steel goes:
$this->bbcode_second_pass_quote('', '[')b]The Major Applications of Steel
Steel applications can be divided into seven primary market sectors. The figures are the percentages of steel production dedicated to them, according to the World Steel Association (WSA):
Buildings and infrastructure, 51%
Mechanical equipment, 15%
Automotive, 12%
Metal products, 11%
Other transport, 5%
Domestic appliances, 3%
Electrical equipment, 3%
Buildings and InfrastructureMore than half of the steel produced annually is used to construct buildings and infrastructure such as bridges. Most of the steel used in this sector is found in reinforcing bars (44%); sheet products, including those used in roofs, internal walls, and ceilings (31%); and structural sections (25%). In addition to those structural applications, steel is also used in buildings for HVAC systems and in items such as stairs, rails, and shelving.
Besides bridges, applications for steel in transportation-related infrastructure include tunnels, rail track, fueling stations, train stations, ports, and airports. Steel is also widely used in utility infrastructure, including for fuels, water, and, electricity. The WSA states that half of the steel used for utility infrastructure is in the form of underground pipes for water or natural gas.
Mechanical EquipmentThis second-greatest use of steel includes (among many other things) bulldozers, tractors, machinery that makes car parts, cranes, and hand tools such as hammers and shovels. It also includes the rolling mills that are used to shape steel into various shapes and thicknesses.
AutomotiveOn average, almost 2,000 pounds, or 900 kilograms, of steel is used to make a car. About a third of that is used in the body structure and exterior, including the doors. Another 23% is in the drive train, and 12% is in the suspension.
Metal ProductsThis market sector includes various consumer products such as furniture, packaging for food and drinks, and razors. Foods packaged in steel cans don't need to be refrigerated.
Other TransportSteel is used in ships, trains and train cars, and parts of planes. Hulls of large ships are almost all made of steel, and steel ships carry 90% of global cargo. almost all of the world's approximately 17 million shipping containers are made of steel. Besides the cars, steel shows up in trains in the wheels, axels, bearings, and motors. In airplanes, steel is crucial for engines and landing gear.
Domestic AppliancesClothes washers and dryers, ranges, microwave ovens, dishwashers, and refrigerators all contain steel in varying amounts, including the motors, when applicable. According to the American Iron and Steel Association, a front-loading washer generally contains 84.2 pounds of steel, while a top-bottom refrigerator-freezer contains 79 pounds.
Electrical EquipmentThe last major steel market sector involves applications in the production and distribution of electricity. That means transformers, which have a magnetic steel core; generators; electric motors; pylons; and steel-reinforced cables.
