Import Tips
• Certify compliance with regional snow/wind loads (e.g
• ASCE 7) particularly for mono-pitch designs prone to drift loading
• Use protective wrapping that allows visual inspection of truss configuration without full unpacking
• Maintain manufacturing records showing finger-jointing and metal plate fabrication to prove non-lumber status
