Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard carbon steel tools for cutting or forming, leading to contamination and reduced corrosion resistance.Employ dedicated stainless steel cutting blades and forming dies to prevent cross-contamination and maintain material integrity.
Inadequate edge preparation for welding, resulting in weak or porous welds.Thoroughly clean and bevel edges before welding to ensure optimal weld penetration and strength.

Common Applications

  • Heavy-duty drain covers and grates
  • Custom fabricated sink and countertop bases
  • Corrosion-resistant enclosures for janitorial equipment

⚠️ Engineering Warnings

  • Avoid contact with chlorides and strong acids, which can cause pitting and crevice corrosion.
  • Ensure proper ventilation and personal protective equipment when cutting or grinding to avoid inhaling metal dust.
