Steel is a high-strength, durable alloy composed mainly of iron and carbon, with small amounts of other elements added to enhance its properties. It is one of the most widely used construction and industrial materials due to its excellent strength, toughness, and versatility. Steel offers superior resistance to tension, impact, and deformation, making it suitable for heavy-duty applications. It is available in various grades, shapes, and finishes such as sheets, bars, rods, beams, and coils. Steel is extensively used in construction, infrastructure, automotive, manufacturing, machinery, and engineering projects for its reliability, long life, and cost-effectiveness.
