Steel is perhaps the most prevalent material in the construction industry. From making bridges, factories, and buildings, to ships and cars, steel is ubiquitous in almost every industrial sector. An alloy of iron, carbon, and other metals, structural steel has been used for several years due to its strength and toughness. These key traits are critical to constructing durable buildings and creating long-lasting vehicles and ships, among many others. Structural steelwork is needed to form a building or any structure’s framework. Thus, making sure that the steel remains strong despite being cast, molded, deformed, riveted, bolted, and welded together, is vital for sustainability. As the backbone for any commercial and industrial structure, there are some essential things to know about structural steel and steelwork. Understanding what steel is, how it’s made, and the various applications of steelworks will be discussed in the succeeding sections.
