Draw exact J-channel, window trim, corner trim, and sill flashing profiles on a 1/4-inch precision grid — get instant fabrication pricing and place your order without a shop visit or a phone call.
Siding jobs stall when the custom trim or flashing order is delayed. The old sketch-and-call process burns hours you don't have.
Sill flashing leg lengths, reveal depths, and hem returns get lost in translation between your sketch and the shop's brake operator.
Waiting days for a quote — and then more days for approval — pushes job starts back and kills your crew efficiency.
Custom trim ships on long bundles. Freight costs can swing a bid unexpectedly if you don't know them up front.
A misread on a corner trim angle or J-channel depth means field modification or a full re-order — both expensive.
Trimgy's grid-based drawing tool gives you the control you need to specify custom siding trim without ambiguity.
Snap every leg, return, and hem to a real measurement. Draw sill flashings, corner trim, and J-channel profiles exactly as you need them — no eyeballing.
Specify 26 ga. or 24 ga. steel, aluminum, or Galvalume. Choose coil-painted colors for matching trim-to-siding aesthetics. Price updates instantly.
Material cost plus real LTL freight to your job-site zip code — all visible before you commit, so your bid is locked and margin is protected.
Stripe-secured payment. Your exact drawing goes directly to fabrication — no middlemen re-entering your specs.
Save your most-used J-channel or corner trim profiles. Reuse them across multiple jobs and just change the footage quantity.
Type what you need: "3.5-inch J-channel with 1/2-inch hem and 1-inch nail flange." AI drafts the profile; you adjust and approve.
From standard starter strip to complex wrap corners, Trimgy can produce fabrication drawings for any straight-line trim profile.
A siding contractor bidding 60 window openings needs a consistent, custom aluminum window head flashing. Here's the Trimgy workflow.
Sketch head flashing on paper on-site — 4" face, 2" top flat, 1" return — photograph and email
Wait 2 days for a quote that comes in without freight included
Call freight broker separately for 200 LF of aluminum trim — add 3 more days
Re-bid the job with a price you still aren't sure about
Draw the head flashing profile — 4" face, 2" top, 1" return — snapped to grid in 3 minutes
Select .032" aluminum, enter 200 LF — material price populates instantly
Enter job-site zip — freight quote appears. Total landed cost known immediately
Lock in the price, place the order — fabrication confirmed before leaving the site
Total time: under 10 minutes. Bid is accurate, order is in, no waiting.
Trimgy supports all common siding trim profiles that can be brake-formed: J-channel, Z-bar (Z-closure), inside and outside corner trim, window surround trim, head and sill flashing, transition Z-bar, starter strip, and custom architectural trim. Profiles are drawn on a 1/4-inch precision grid and fabricated to the exact dimensions specified.
For most commercial siding applications, .032" or .040" aluminum is preferred for its corrosion resistance, light weight, and compatibility with most siding systems. Galvalume steel (24–26 ga.) is an alternative where rigidity is important. For applications requiring color matching to a specific paint system, Kynar-painted steel offers a 20-year fade warranty. Aluminum is the most common choice for window and door surround trim.
Yes. Trimgy supports Kynar 500 / PVDF-coated steel and aluminum in standard color ranges. For custom color matches to specific manufacturer palettes, lead times are longer (typically 3–5 weeks) as the coil stock must be sourced. Standard Kynar colors are typically available in 2–4 weeks. For standard unpainted galvanized or Galvalume, lead time is 2–5 business days.
Custom sheet metal siding trim ships via LTL (less-than-truckload) freight in 10 to 12-foot bundled sections. Trimgy calculates an LTL freight quote to your delivery zip code using CH Robinson rate data as part of the ordering process, so you see the full landed cost before committing. Transit time is typically 1–2 business days for regional delivery and 4–7 days for cross-country shipments.
