Typically carbon steel with varying amounts of manganese and other alloys

Generally low to medium carbon content

Manganese, silicon, and sometimes small amounts of other elements

Moderate resistance to corrosion, depending on the environment

Generally weldable with appropriate techniques

High ductility, allowing for bending and shaping

High tensile strength, crucial for structural integrity

Excellent yield strength for load-bearing capacity

Adequate elongation properties for construction flexibility

Usually not hardened, remains ductile
