About

A36 steel is a low-carbon structural steel widely used in general-purpose fabrication and construction. It offers good strength, toughness, and weldability at a low cost, making it a popular choice for structural components, brackets, frames, and base plates. A36 machines reasonably well but is softer than alloy steels, so it’s better suited for parts where high wear resistance or tight tolerances are not critical. It has low corrosion resistance and is typically coated, painted, or otherwise protected when used in exposed environments. A36 is ideal for functional parts where strength and affordability matter more than finish or precision.
