Grain Bin Sidewall Sheet Inspection

Inspection template for formed grain bin sidewall sheets to verify corrugation geometry, hole pattern, coating condition, and tensile grade for fit-up and structural strength.

Inspection Identification

• Inspection date and time recorded
• Sheet lot, coil, or batch identifier recorded
• Inspector name and department recorded
• Reference drawing, specification, or work order available

Corrugation and Form Accuracy

• Corrugation profile matches specified shape and pitch
  Verify the formed corrugation geometry matches the approved bin sheet specification and does not show flattening, distortion, or inconsistent pitch.
• Sheet length, width, and formed dimensions within tolerance
  Record the measured dimensional deviation from specification. Use the approved tolerance from the drawing or customer specification.
• Edge condition free of cracks, splits, or burrs that affect fit-up
• Hole pattern matches spacing, diameter, and alignment requirements
  Check punched holes for correct count, spacing, diameter, and alignment so panels will assemble properly with mating sheets and fasteners.

Coating and Surface Condition

• Protective coating is continuous and uniform
  Inspect galvanized or painted surfaces for bare spots, thin coverage, peeling, blistering, or other coating defects that could reduce corrosion resistance.
• Visible rust, oxidation, or corrosion present
• Surface is free of dents, oil canning, or deformation affecting assembly
• Cut edges and punched areas show no coating damage beyond acceptable limits

Material Grade and Traceability

• Specified tensile grade verified against mill certificate or material record
  Confirm the sheet material grade meets the approved tensile requirement for the bin design and is traceable to documentation.
• Mill certificate or material test report attached
• Heat number or traceability code legible on sheet or packaging

Acceptance, Non-Conformance, and Sign-Off

• Inspection result
• Non-conformance or deficiency documented with disposition
  Record any deficiency, segregation status, rework, replacement, or supplier notification required.
• Inspector signature
