Standard delivery documents for angle steel include:
1) Certificate of Quality (CoQ): Confirms compliance with GB/T 706/ASTM/EN standards, listing chemical composition (e.g., C=0.18% for Q235B), mechanical test results (tensile strength=450MPa), and batch number;
2) Delivery Note: Details quantity (e.g., 50 pieces of ∠50×5×6m), specifications, gross/net weight, and consignee information;
3) Inspection Report: Includes dimensional data (side length tolerance ±0.5mm), surface quality checks (no defects), and ultrasonic testing results (for internal cracks in thick-angle steel ≥16mm);
4) Material Safety Data Sheet (MSDS): Provides handling precautions (e.g., avoid impact to prevent deformation) and storage guidelines (keep dry). For exports to Europe, a CE certificate (per EN 10204 Type 3.1) is mandatory to prove compliance with EU construction standards.
