Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard fasteners that may corrode alongside the stainless steel.Utilize 304 or 316 stainless steel fasteners to prevent galvanic corrosion and maintain material integrity.
Exposing the sheet to abrasive materials without proper protection during handling.Employ protective coverings, such as plastic film or felt pads, during transport and installation to prevent surface scratching.

Common Applications

  • Custom fixture and jig fabrication
  • Calibration standards and reference surfaces
  • Work surfaces for precision assembly and inspection

⚠️ Engineering Warnings

  • Always wear appropriate personal protective equipment (PPE) when handling metal sheets.
  • Exercise caution to avoid sharp edges and potential pinch points during manipulation.
