Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard carbon steel fasteners that can corrode and stain the stainless steel.Always use 304 or 316 stainless steel fasteners for all connections and mounting hardware.
Insufficient edge preparation before welding, leading to potential weld defects.Properly bevel and clean the edges of the 0.770" thick sheet before initiating any welding process.

Common Applications

  • Heavy-duty protective shipping enclosures
  • Custom industrial machine guards
  • Corrosion-resistant fabrication components
