Short answer: Before accepting a metal lot, verify the mill test certificate and chemistry, check dimensions against tolerance, inspect surface and coating, confirm mechanical properties by test, and confirm export packing — so the delivered material matches the purchase spec.
At a Glance
Certificate and Chemistry
The mill test certificate proves grade and heat; our Mill Test Certificate Guide shows what to read, and our Tolerances Guide sets the dimensional limits you should check.
Dimensions and Surface
Measure key dimensions and inspect surface and coating for defects; the finishing side is in our Surface Treatment Guide and the corrosion case in our Corrosion Resistance Guide.
Mechanical and Property Tests
Tensile, hardness and bend tests confirm the grade performs; the strength data is in our Comparación de fuerzas and the families in our Stainless Steel Supplier y Carbon Steel Supplier.
Packing and Receipt
Confirm export packing protects the lot in transit; our Export Packing Guide lists what good packing looks like so you receive clean, undamaged material.
