A36 steel coils (a common carbon structural steel compliant with ASTM A36 standard) are widely used in construction for manufacturing light steel frames, roof/wall cladding panels, prefabricated building components, and temporary engineering support structures, leveraging good weldability and basic load-bearing capacity. They are applied in machinery manufacturing for non-high-load equipment bases, sheet metal parts, and simple structural brackets. In municipal infrastructure, they are used to make street lamp poles, road guardrails, and low-pressure drainage system components. Additionally, they find use in the agricultural sector for farm greenhouse frames and agricultural machinery auxiliary parts, in the packaging industry for medium-strength steel drums, and in general industrial fields for small-scale fluid transport pipeline casings, benefiting from cost-effectiveness and easy processing.
