Valley: A valley is created by two intersecting slopes of a metal roof. Valley trim, installed prior to panels in the valley area, is a raised section at the low point of the “valley” to prevent water from traveling up the opposite slope and penetrating the roof.
Ridge Cap: Used on top of the ridge line or hip of a roof, a ridge cap sits on top of the rib of a metal roofing panel to allow adequate space for ventilation when used with a ventilated closure strip.
Gable Rake: Also known as rake trim, gable trim is a finishing piece of metal flashing used along the edges of a metal roof line where the edge of the metal roof panel meets the endwall panels.
Drip Edge: Eaves are the overhanging edges of the roof over the sidewall panels. They help direct water away from walls and windows. Eave trim, also referred to as an eave drip, is installed at the edge of metal roof panels, creating a finished appearance and helping to redirect rain run-off away from fascia and soffits.
Endwall: Prevents water from penetrating or seeping under a roof. It’s typically installed around roof hips and ridges, chimneys, vent pipes, skylights, and anywhere there are joints or two pieces of roofing that meet, or where a roofing panel intersects with a wall or other structure.
Fascia: fascia. Trim is the material used to encase windows and doors, among other features, on a home’s exterior. Fascia is a horizontal or angled board that encloses the edge or face of the projecting eaves.

Transition Trim: The transition flashing prevents leakage at the point where two different roof pitches meet. It must be sealed on the lower side with outside closures, and can be sealed underneath the upper panels with inside closures. The similar gambrel flashing is used where the lower pitch is steeper than the upper.
J-Channel: J-Channel flashing is designed specifically for trimming out openings around your wall panels. Windows, doors and louvers on the walls of your building blend in seamlessly when J-Channel is installed. J-Channel hides the cut lines of panels giving your project a clean finished look.

Outside Corner: Corner and trim serves as a cover and trim for steel siding at outside corners.
Inside Corner: Corner and trim serves as a cover and trim for steel siding at inside corners.
Post Trim: The post trim frame a door. Metal trim is installed vertically along the sides of a wall opening.
Overhead Door Trim: Is a combination trim that caps off the panel edge and covers door jamb.
Drip Cap: Seals off the ends of panels above doors and windows.
Track Cover: It conceals sliding tracks from the rain and corrosion.
Base Guard: Base drip seals off the bottoms of panels at the floor level, where it helps to prevent the entrance of rodents and insects, as well providing a base for the setting of panels.
Double Angle: Connects two side wall panels and seals both ends of the metal at the same time.
