| Fasteners | Concealed | Exposed screws |
| Thermal movement | Panels float freely | Fastener holes can elongate |
| Weather resistance | Superior | Fastener washers require inspection |
| Appearance | Clean, architectural | Visible fastener rows |
| Longevity | Longer service life | Good service life with maintenance |

Panel Profiles
Snap-Lock vs. Mechanical Lock
The two main standing seam profiles differ in how the seam is formed.
Snap-lock (field-formed)
Panels snap together on-site without a seaming tool. Faster to install and well-suited to steeper pitches.
Mechanical lock (double-folded seam)
Seams are mechanically folded on-site using a seaming tool. Preferred for lower slopes and longer panel runs.
