Supersider 1-1/2 in. White Step Flashing | 26ga Steel | Sold Per Ft

Pricing and Lengths Are Simple: Sold Per Linear Foot

This Supersider step flashing is priced by the linear foot. Select the total number of feet needed for your project, then confirm whether the material will be shipped, picked up, or delivered locally.

Shipping length limit: individual shipped pieces are limited to 8 ft maximum length because long items become expensive and inefficient to ship.

Need longer pieces? Longer lengths may be available for local pickup or local delivery in the Portland metro / Damascus, Oregon service area.

The Detail Piece That Makes Exterior Transitions Look Finished

Roof edges, wall transitions, siding breaks, fascia areas, and metal trim intersections are the places customers notice when finish work looks rough. This Supersider profile gives installers a formed white steel trim piece for a cleaner, sharper exterior detail.

The main buying reason: get a formed 1-1/2 in. white trim profile that helps roof, siding, fascia, and gutter-adjacent details come together cleanly without field-bending flat material for every run.

1-1/2 in. Supersider Profile for Siding Integration

The 1-1/2 in. profile is built for exterior trim and flashing detail work where siding, roofline, fascia, and metal components need a clean transition. The formed shape creates a defined step and return that helps the piece sit into the detail when matched to the right project conditions.

Use it where the exterior needs a crisp white trim line instead of a rough exposed edge.

26 Gauge White Steel for Exterior Metal Detail Work

The 26 gauge steel construction gives this trim piece a sturdy exterior feel while keeping the profile workable for professional installation. The white finish makes it a strong match for common fascia, soffit, siding, trim, and light-color exterior packages.

Handle with clean gloves, protect the finish during cutting and fastening, and touch up exposed cut edges when the project calls for it.

Strong Fit for Roofers, Siders, Gutter Crews, and Remodelers

This trim profile is useful around the exterior details gutter and roofing crews often run into: roof edges, fascia returns, siding transitions, wall tie-ins, trim breaks, and areas where water-shedding details need to look clean after gutter or roofline work is complete.

It is not just bent metal. It is the piece that keeps the exterior detail from looking like three trades shook hands and left early.

Confirm the Detail Before Cutting

Exterior trim work depends on the siding system, wall condition, roof slope, flashing sequence, gutter placement, overlap, fastener type, and local requirements. Test fit the profile before cutting project quantities.

This piece should be installed as part of a properly planned exterior water-management assembly, not as a shortcut around correct flashing practice.

Built for Clean Exterior Transitions

How to Order the Correct Length

1. Measure the total linear footage needed for the roof edge, siding break, wall transition, or fascia detail.
2. Add extra footage for waste, overlap, field cuts, and layout changes.
3. Enter the total number of feet needed.
4. For shipping, plan pieces at 8 ft maximum length.
5. For longer pieces, choose local pickup or local delivery when available.
6. Confirm color, profile, length, and delivery method before placing the order.
7. For project quantities, check availability before scheduling installers.

Shipping Length Notice

Shipping is limited to 8 ft maximum piece length. Long trim pieces are costly to package, protect, and ship, so 8 ft sections are the practical shipping limit.

Need 10 ft, 12 ft, or longer pieces? Choose local pickup or local delivery if available for your project area.

If the order needs special handling, multiple bundles, or delivery to a jobsite, confirm the details before ordering.

Installation and Handling Notice

Confirm this profile matches the project detail before cutting or fastening. Exterior water-management details depend on the full assembly, not one trim piece by itself.

Use compatible exterior-rated fasteners, proper overlap, correct sequence, and approved sealant where required by the project conditions.

Store flat and dry, protect the white finish, and handle with gloves to reduce scratches, fingerprints, and coating damage.

Follow professional installation practices and local requirements for roofing, siding, flashing, and exterior water control.
