One of the most important resources in construction, whether it be building bridges, buildings or other large structures, is structural steel. The material has a long list of benefits that are imperative to companies that build and maintain our country’s infrastructure.
For many projects, structural steel forms the backbone. That’s why it is so imperative that the complex and demanding process that is required to form the material and adapt it to whatever it will become a part of are so important. When it’s not handled correctly, there are obvious risks associated with a project’s long-term viability.
While the shorthand version of how structural steel is created involves heating iron up and adding certain substances to achieve specific properties, the long version is much more involved.
Raw iron is the chief ingredient, but it is rarely found pure in nature. Most often it already contains carbon, but usually in too high a concentration. Some carbon needs to be removed, but not all. Because of that, the manufacturing of steel products can be an involved process.
Once the steel has been created, it is formed into a number of different configurations, depending on how it will be used. Beam, channel, angle, plate and hollow steel tube are the most common.
There are a number of different configurations you can find it in, but for the most part, it is all the same stuff inside. Just like other types of steel, the main components are iron and carbon. The more carbon that is added to the alloy, the higher the strength and lower the ductility of the finished product. Other chemicals or substances can be added in the production process that can:
One of the most common additions to structural steel, after iron and carbon, is manganese. Manganese improves the machinability of steel, and also help bind steel better to resist cracking and splitting during the rolling process.
The ratio of carbon in structural steel is important when considering how the metal will be used. While lower carbon content makes it easier to weld, it also can make the material harder to work with overall, which lowers the speed it can be constructed with. Finding the perfect balance is important when considering its use.
The resulting steel product has an excellent ratio of low weight to immense strength, making it the perfect construction material.
Even after it has been formed into shape, structural steel still requires fabricating and welding. A skilled fabricator or welder can take advantage of the relative malleability of structural steel to create whatever shape is needed for a specific application.
Welding is largely replacing riveting as the chosen method of fabricating structural steel, and with good reason. Welded structures are:
