Siding & Trim
Aluminum Fascia, Soffit, F-Channel & Starter Strip
Aluminum trim coil and accessories that finish a clean residential siding install. Pre-bent fascia covers nominal 1×6 wood fascia board, vented soffit ties into the soffit-to-ridge ventilation pair, F-channel receives the soffit at the wall, and starter strip sets a level reference for the first siding course.
Built for Performance. Designed for Life.
Builder-Grade Material
Aluminum trim coil, galvanized steel, and engineered membranes. Honest gauges, honest specs.
Finish-Matched to the Lineup
Black and White on every aluminum profile so your fascia, soffit, drip edge, and F-channel read as one system.
Project-Ready Lengths
Standard 10' and 12' lengths sized for residential framing. Coil nails ship by the carton, membranes by the roll.
The Siding & Trim Lineup
Four builder-grade SKUs, sized and gauged for residential work, finish-matched across the line.
Aluminum Fascia
1×6″ × 12′ · .020″1″ × 6″ × 12′
Pre-bent aluminum fascia cover for capping wood fascia board. 12-foot lengths cover a full standard rafter run cleanly.
Aluminum Soffit
12″ × 12′12″ × 12′ Vented Panels
Vented aluminum soffit panels for residential overhangs. Continuous ventilation, no rot risk, paint match to fascia.
Aluminum F Channel
10′ · .016″18mm × 28mm × 10′
F-profile receiver channel for terminating soffit panels at the wall. Cleaner than J-channel for retrofit installs.
Metal Starter Strip
10′ · .015″3¾″ × 10′
First-course starter for vinyl and aluminum siding. Locks the bottom of the first panel and sets a level reference for everything above.
Frequently Asked Questions
Specs (gauge, length, coverage, weight) follow standard residential conventions, but our building materials are not currently sold with code-compliance certifications (ASTM, UL, etc.). If your code official requires documented testing for a specific assembly — e.g. wind-resistance testing on synthetic underlayment, or fire-rating on an ice-and-water shield — contact us before specifying and we'll confirm what documentation is available on a SKU-by-SKU basis.
Yes. Larger orders ship from our Michigan warehouse on standard 40" × 48" pallets, and full-container or partial-container quantities can be sourced direct. Email sales@shorelinebrand.com with a takeoff and we'll quote.
Specs are shown in both. Aluminum trim coil is most often spec'd in thousandths-of-an-inch (.018", .024") in the US, while our manufacturing partners spec in mm. We carry both on every spec table so you can match a takeoff against either standard without doing conversion math on site.
The Black soffit is 0.38mm and the White is 0.40mm — a real and intentional spec difference, not a typo. For most residential soffit applications the 0.02mm spread is below the threshold a builder will notice or specify against, but we list both so the spec sheet is honest. Both are well within the 0.35–0.45mm range typical of residential aluminum soffit.
In-stock SKUs ship in 3–5 business days from Michigan. Out-of-stock or larger-than-warehouse-quantity orders ship 40–45 days after the PO lands, which is standard container lead time from origin. We'll confirm the schedule on every quote.
Warranty & Care Guide
Shoreline Brands stands behind every product we manufacture.
Our building materials carry a limited warranty against manufacturing defect. Specific terms — duration, exclusions, and coverage tier — vary by product and by manufacturing partner. Contact us for product-specific warranty documentation before specifying for a project that requires written warranty terms.
Painted aluminum trim coil is warrantied against checking, peeling, and chalking under normal residential exposure. Specific warranty period varies by SKU.
Warranty Coverage
- Manufacturing defects
- Material substitution
- Painted-finish checking and peeling under normal residential exposure
Warranty Exclusions
- Damage from improper installation or out-of-spec fasteners
- Cosmetic surface damage incurred after delivery
- Performance claims requiring third-party testing (ASTM, UL, etc.) — these are not currently warranted on our building-materials line
Care Guide
Storage Before Install
- •Store trim coil and flashing flat, off the ground, under cover. Bowed coil resists straightening once it's taken a set.
- •Keep underlayment and ice-and-water shield rolls on end (not laid flat) to prevent core distortion.
- •Coil nails: keep in original cartons, indoors, until install. Field-stored cartons soak humidity and corrode prematurely.
Field Cuts and Edges
- •Cut aluminum with aviation snips or a fine-tooth blade. Don't use abrasive cut-off wheels — heat discolors the paint at the cut.
- •Cut galvanized steel with snips; seal the cut edge with zinc-rich primer in high-moisture exposure to prevent edge rust.
- •Touch up scratches or scuffs on painted aluminum with matching color-matched paint before exposure to weather.
