Large metal supports come in various forms, including beams, columns, and girders, each designed to withstand significant loads and environmental stressors. The materials used in manufacturing these supports, typically steel or reinforced alloys, are chosen for their strength-to-weight ratio, durability, and resistance to corrosion. For instance, the use of galvanized steel, which is coated to prevent rust, is particularly prevalent in environments that may be exposed to moisture or chemicals, enhancing the lifespan of the structural components.
