Structural steel is the workhorse of construction and heavy engineering, valued for its balance of strength, weldability and cost-efficiency. PacSteelCorp supplies structural steel plates, pipes and sections to major international standards such as ASTM A36 and EN 10025 (S235/S275/S355) and their equivalents. Typical uses include building frames, bridges, industrial platforms, warehouses and general fabrication. Each standard below lists representative grades with chemical composition, mechanical properties and typical applications to help engineers and buyers specify the right material.
