Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using undersized fasteners or inadequate fastening density.Utilize fasteners with sufficient shear strength and tensile capacity, and adhere to recommended spacing to ensure the sheet is securely anchored and can withstand intended loads.
Not accounting for potential thermal expansion or contraction.In applications with significant temperature fluctuations, incorporate expansion joints or slots in the mounting points to prevent stress build-up and material deformation.
