Steel
What is Steel?
Steel is an alloy made primarily of iron and carbon, used extensively in construction for its strength and durability. To fully understand the meaning of steel, one must consider its role in construction, manufacturing, and various industries due to its versatility and ability to be recycled without degradation in quality. Steel's properties can be enhanced by adding other elements, such as chromium, nickel, and molybdenum, which improve its rust resistance, increase strength at high temperatures, and enhance hardness. Understanding how to select steel for construction is important in ensuring the safety, stability, and longevity of the planning and building process.
How is Steel Made?
Steel is produced by smelting iron ore to remove impurities, then adding carbon. This process is refined through methods like Basic Oxygen Steelmaking (BOS) or Electric Arc Furnace (EAF) methods to produce various steel grades.
Steel Grades and Their Uses in Homebuilding
Each grade of steel possesses distinct properties suited for different aspects of homebuilding:
1. Structural Steel: These grades are used in the framing of houses for beams, columns, and foundation supports, providing a skeleton that is both sturdy and resilient against various stresses.
2. Rebar Steel: Rebar, a reinforcement steel, is crucial in the construction of foundations, driveways, and sidewalks. It helps concrete withstand tension and pressure, preventing cracks and structural failures.
3. Stainless Steel: Known for its resistance to corrosion and staining, stainless steel is used in areas prone to moisture, such as kitchens and bathrooms. Its aesthetic and durability make it ideal for fixtures, handles, and appliances.
4. Galvanised Steel: This steel is coated with zinc to protect it from corrosion. It's commonly used in outdoor applications like roofing, gutters, and fencing, offering longevity against weather elements.
