Steel is everywhere in construction, to the beams holding roofs up to the sceletons of entire buildings, down to the very tools you use. Steel isn&#;t just one thing though&#;there are many different kinds of steel and different steel shapes, each with its own purpose and use. Learn more about the different kinds of structural steel how it&#;s used in construction.
Structural steel is metal used in construction materials. Fundamentally, it is defined as steel optimized for use in building construction&#;differentiated from a steel grade one might use to engineer tools, or stainless steel popularly used in kitchen surfaces and appliances.
Structural steel is generally a carbon steel, meaning it has a chemical composition containing both iron and carbon. Structural steel is any category of steel with a carbon content of up to 2.1% of its total weight. The higher the carbon content, the higher a piece of steel&#;s yield strength&#;meaning it is less ductile, or less likely to bend or warp when pressure is applied.
One might think steel used in construction should have a relatively high carbon content because it is less likely to bend under pressure. However, low-carbon steel, also known as &#;mild steel,&#; is actually the most commonly used type of steel in building materials. It typically contains anywhere from 0.04% to 0.3% carbon content, rendering it strong yet ductile. Steel buildings, especially tall steel buildings, must be strong, but also somewhat flexible. Overly rigid buildings cannot accommodate natural shiftings in the earth, which can be caused by neighboring construction or even earthquakes, nor can they bend with high winds. For this reason, mid- to high-carbon steels, with carbon content ranging from 0.31 to 1.5%, while technically considered structural steel, are generally reserved for mechanical engineering and toolmaking purposes.
Other grades of structural steel might contain other alloying elements, such as tungsten, zirconium, cobalt, or nickel.

There are many various advantages of structural steel construction.
But there are a few disadvantages of building with structural steel too. It is susceptible to corrosion, and making it resistant to such processes can be costly. It is also susceptible to fatigue and buckling, with measurable decreases in strength in higher temperatures.

Contact us to discuss your requirements of Structural Steel Vs Mild Steel. Our experienced sales team can help you identify the options that best suit your needs.
Structural steel is the backbone of the construction industry, being used in everything from buildings to bridges to homes &#; just about everywhere. This versatile material is known for its exceptional strength and durability, making it one of the best choices in the construction industry.
Structural steel is also a preferred construction material due to its high strength-to-weight ratio, meaning that it can support heavy loads without adding unnecessary weight to a structure. Structural steel is also resistant to fire, which is another reason why it is often used in building construction.
If you&#;re looking to purchase structural steel in bulk, here are the types you should be in the market for, as well as their benefits to your project.
There are several different types of structural steel, each of which has its own unique properties. Depending on your project, you&#;ll want to source the correct type.
Mild steel is a type of carbon steel that is widely used in construction, manufacturing, and other industrial applications. Also known as low carbon steel, mild steel typically includes up to 0.25% carbon, with small amounts of other elements such as manganese, silicon, and sulphur. The low carbon content of mild steel makes it relatively soft and malleable, which means it is easy to shape and form using a variety of techniques such as welding, cutting, and machining.
Despite its low carbon content, mild steel is still strong and durable, with a tensile strength of around 400 MPa (megapascals). It is also resistant to corrosion and other forms of wear and tear, although it is not as corrosion-resistant as other types of steel such as stainless steel. In addition to this, mild steel is on the more affordable end of the scale when it comes to steel products.
Carbon steel is a type of steel that contains varying amounts of carbon as the primary alloying element. In general, carbon steel contains between 0.05% and 2.0% carbon by weight, although this can vary depending on the specific grade and application.
Carbon steel is one of the most widely used types of structural steel in construction, manufacturing, and other industrial applications due to its strength, durability, and versatility. It is a popular choice for everything from building frames and bridges to automotive parts, machinery, and tools. It&#;s also divided into a number of classes, including:
While not as commonly used as mild or carbon steel, stainless steel is a popular choice for certain structural applications. It is highly resistant to staining, making it ideal for structures in harsh or corrosive environments. Due to stainless steel containing a minimum of 10.5% chromium by weight, stainless steel has some unique characteristics including its resistance to corrosion, staining, and rust.
Similarly to carbon steel, There are several different grades of stainless steel, each with its own unique properties and applications. Some of these common grades are:
HSLA steel is a type of carbon steel that contains small amounts of alloy elements such as copper, nickel, and chromium. These elements enhance the strength and toughness of the steel, making it ideal for structural applications that require high strength and durability.
Alongside its strength, HSLA steel also has good ductility, which means that it can be bent and shaped without breaking. This makes it easier to work with than other high-strength materials such as brittle cast iron or high-carbon steel. It also has a number of classifications, including low-alloy steels, high-strength low-alloy steels, dual-phase steels, and transformation-induced plasticity steels &#; all HSLA structural steels with a range of strengths and treatments to create solid steel product.
Lastly, we will mention weathering steel in our list of structural steel types. Also known as COR-TEN steel, weathering steel is a high-strength, low-alloy steel that is designed to withstand harsh weather conditions. The composition of weathering steel is similar to that of traditional carbon steel, but with the addition of small amounts of copper, chromium, and nickel. These elements work together to form a stable, corrosion-resistant layer of rust on the surface of the steel, which gives it its characteristic appearance and protects it from further damage.
Due to its durability, weathering steel can withstand prolonged exposure to the elements without significant deterioration. This makes it an ideal material for outdoor applications where longevity and durability are important.
