steel standards
Chinese structural steel design follows GB 50017 with materials to GB/T 700 and GB/T 1591, and execution and acceptance to GB 50205. Welding follows GB 50661 and the JGJ series, and mandatory national standards are enforced through the design review and construction acceptance process.
