1. Thickness Measurement
Use a vernier caliper or micrometer to measure the thickness of the perforated sheet at multiple points to ensure uniformity and compliance with customer requirements.
2. Dimension Inspection
Measure the length and width of the perforated sheet with a measuring tape to confirm that they meet user specifications, avoiding any issues during installation or use.
3. Diagonal Accuracy
Check the diagonal lengths of the perforated sheet to ensure the error does not exceed 5mm, which is essential for maintaining flatness and proper installation.
4. Material Verification
Confirm that the material of the sheet matches the user's requirements, such as stainless steel for corrosion resistance, aluminum for lightweight durability, or iron with galvanization or coating for enhanced performance.
5. Hole Size Consistency
Measure the diameter of the holes to ensure they meet the design requirements. For high-precision applications, the tolerance for hole size must be within acceptable limits.
6. Hole Spacing Measurement
Verify the distance between holes to ensure uniform spacing and compliance with design specifications.
7. Surface Quality Check
Inspect the surface for scratches, burrs, rust, or other defects. Additionally, ensure the surface treatment—such as polishing, coating, or galvanization—meets the required standard.
8. Edge Neatness
Examine the edges of the sheet to ensure they are smooth and free from chips or irregularities, which is vital for safety and aesthetic appeal during installation and use.
