Steel bars are essential components in construction, providing structural support and reinforcement to various building elements. Each group of steel bars possess distinct characteristics that make them suitable for specific applications in different construction projects. In this article, we will study the three distinct categories of steel bars such as Foundational Bars, Structural Support Bars, and Niche Bars. Understanding the differences and applications of these steel bars is crucial to make informed decisions for safe and durable construction.
Foundational Bars
1. Deformed Bar
This first group of steel bars is normally used when creating the foundation of any structure. These bars take on the majority of the load when laying out the cement for structures like walls, floors, and ceilings. A common type of bar from this group is the deformed bar, which gets its name from the ribs that span its surface. These bars sport these ribs to bond better with the concrete. This helps in reinforcing the strength of concrete, as concrete has poor tensile strength.
2. I-Beam
Another bar under this category is the I-Beam. I-Beams are normally used in the construction of steel structural buildings, as they are bigger and there “I” structure – formed by the two horizontal flanges and a vertical component – can carry a much heavier load than the thin, cylindrical deformed bars. With their durable nature, they don’t demand other support structures, making them cost-effective for big projects. Often, they are put together into trusses that support the roofing of warehouses or become supports for ceilings in buildings.
3. Plain Round Bar
The other bar in this category is the plain round bar. This type of bar differs from deformed bars since they don’t sport ribbed surfaces, but a smooth surface. While they can still be used for reinforcing concrete structures because of their properties, they can be used to serve other purposes in a construction project. Just like deformed bars, they are incredibly sturdy, their strength allows them to withstand high pressure, temperature, and impact load. Their elasticity allows them to resist tension, helping them avoid breaking when being stretched and bent. Since they are made of steel, this makes them recyclable for other purposes in the project.
Structural/Support Bars
1. Channel Bars
Two types of steel bars are often used for creating roofs. These are the channel bars and the c-purlins. Channel bars have a U-shaped cross-section, resembling the letter "C." They are frequently used in construction as structural components and support elements, such as in the construction of frames and roof trusses. Channel bars provide excellent lateral support due to their shape.
2. C-purlins
C-purlins are steel sections with a "C" shape. They are essential components in the construction of metal buildings and roofs. C-purlins provide support and stability to the roofing material, helping it withstand wind, snow, and other environmental factors.
3. Rectangular Tubes
This next set of bars helps create other parts of the house or building. Rectangular tubes are hollow steel sections with a rectangular cross-section. They are used for various structural and architectural applications, including constructing frames, fences, and handrails. Their hollow nature reduces weight while maintaining strength.
4. Square Tubes
Square tubes have a square cross-section, making them ideal for applications where torsional strength is required. They are used in construction for constructing frames, supports, and railing systems, offering both strength and aesthetic appeal.
5. Square Bars
Square bars are solid steel bars with a similar square cross-section to the square tubes. They are commonly used in construction for fabrication, as well as in the creation of ornamental structures like balusters, gates, and decorative railings.
Niche Bars
1. Angle Bars
These last few bars all fulfill more niche roles in the construction process. Angle bars, as the name suggests, have an "L" shape and are used to form right angles. They are employed in construction for providing structural support and reinforcement, especially at corners and edges. Angle bars are frequently used in building frames, supports, and brackets.
2. Flat Bars
Flat bars have a rectangular cross-section with a width greater than its thickness. They are versatile and used in various construction applications, including as braces, supports, and connectors. Flat bars are easy to work with and can be cut and welded as needed.
3. Galvanized Iron Pipes
Galvanized Iron (GI) pipes are steel pipes coated with a layer of zinc to prevent rusting. They are commonly used in plumbing and water supply systems in construction. GI pipes are known for their durability and resistance to corrosion, making them suitable for both indoor and outdoor applications.
Steel bars come in a wide range of shapes and sizes, each designed to serve specific construction purposes. Whether you need to reinforce concrete, support heavy loads, create structural elements, or fabricate ornamental designs, there is a steel bar type suited for your needs. Understanding the unique characteristics and applications of these steel bars is crucial for successful construction projects, ensuring safety, stability, and longevity in structures.
