Structural steel refers to heavy steel sections used in construction — beams (I-beams, H-beams), columns, channels, plates, and hollow sections (RHS/SHS tubes). These are among the most common ferrous scrap materials in Auckland, typically sourced from building demolitions, bridge works, and commercial fitouts. Structural steel is classified as heavy melting steel (HMS) when it meets thickness and size requirements. At endless metals, we accept structural steel cut to manageable sizes. Larger pieces may need shearing at the yard before baling for export. Structural steel recycled in New Zealand is exported to electric arc furnace mills where it is remelted into new construction products.
