Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard cutting tools not rated for thick stainless steel, leading to poor edge quality and potential material damage.Utilize specialized cutting equipment designed for thick gauge stainless steel, such as a CNC plasma cutter or a heavy-duty shear, to ensure clean and precise cuts.
Inadequate surface preparation before installation, compromising adhesion or structural integrity.Thoroughly degrease and clean the mounting surface and the stainless steel sheet before commencing installation to ensure optimal contact and adhesion.

Common Applications
