Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard cutting tools not rated for thick stainless steel.Employ heavy-duty, sharp cutting blades (e.g., carbide-tipped) designed for thick stainless steel to prevent blade damage and ensure clean cuts.
Neglecting proper material handling and storage.Handle with care to avoid scratches and deformation. Store flat in a dry environment to prevent surface contamination and corrosion.
