An angle steel label contains critical details for identification, compliance, and traceability:
Manufacturer's information: Name, logo, or plant code of the producing steel mill, enabling customers to verify the supplier.
Material standard and grade: Specifies the industry standard (e.g., ASTM A36, EN 10025-2, JIS G3101) and grade (e.g., S355JR, SS400), ensuring compatibility with project requirements.
Dimensions: Leg length (e.g., 50x50mm), leg thickness (e.g., 5mm), and length of the angle steel (e.g., 6m, 12m), providing essential size details for installation.
Heat number: A unique alphanumeric code linking the angle steel to its production batch, allowing traceability to mill test reports and production records.
Weight: Per-meter weight (e.g., 3.77 kg/m) and total weight per piece, aiding in logistics planning and cost calculation.
Certification marks: Symbols like CE (for European compliance), ASTM certification, or JIS marks, confirming that the product meets regional quality and safety standards.
Coating details (if applicable): Information about protective coatings, such as hot-dip galvanization (with thickness specified, e.g., 85μm) or epoxy paint, indicating resistance to corrosion.
Labels are printed on durable, weather-resistant materials (e.g., plastic or metal tags) attached to angle steel bundles, or directly stamped/etched onto the surface to withstand transportation, storage, and harsh job site conditions.
