Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard cutting tools not rated for thick stainless steel, leading to poor cut quality and tool damage.Utilize specialized cutting equipment such as a heavy-duty shear, waterjet, or plasma cutter with appropriate settings for 0.351" 304 stainless steel.
Failing to properly deburr cut edges, leaving sharp burrs that can cause injury or damage to mating components.Thoroughly deburr all cut edges using a file, deburring tool, or grinding wheel to achieve a smooth, safe finish.

Common Applications

  • Custom fabricated drain pans and sumps
  • Durable work surfaces for janitorial stations
  • Corrosion-resistant components for industrial washing systems

⚠️ Engineering Warnings

  • Always wear appropriate personal protective equipment (PPE), including safety glasses and heavy-duty gloves, when handling and cutting stainless steel.
  • Ensure proper ventilation when performing cutting or grinding operations to avoid inhalation of metal dust or fumes.
