TL;DR
Trim coil is factory-painted aluminum sheet sold in rolls, typically 24 inches wide and .019 inch thick, that siding installers bend on a portable brake into custom cladding for fascia boards, window brims, door casings, and other exterior wood trim. It seals weathered trim behind low-maintenance metal, matched in color to the siding line, with hems folded into the edges for stiffness and clean lines.
What it means
Trim coil is factory-painted aluminum sheet sold in rolls, typically 24 inches wide and .019 inch thick, that siding installers bend on a portable brake into custom cladding for fascia boards, window brims, door casings, and other exterior wood trim. It seals weathered trim behind low-maintenance metal, matched in color to the siding line, with hems folded into the edges for stiffness and clean lines. Wavy, oil-canned bends and face-nailing that invites leaks are the marks of rushed work, since every profile is shaped by hand on site.
