Draw your exact K-style, box gutter, commercial box gutter, or scupper profile on a precision grid — get instant material pricing with freight and place your fabrication order online.
Most gutter contractors and sheet metal shops still rely on hand-drawn profiles, phone quotes, and days of waiting for custom gutter fabrication orders — a process that slows every job.
A box gutter with a specific outlet position, overflow slot, or fascia return looks straightforward on a sketch but gets interpreted differently by every shop.
Gutter sections in 10- to 20-foot lengths ship as long LTL freight. Not knowing that cost upfront makes it hard to bid accurately.
Commercial built-in or box gutters are project-specific. Calling three shops for competing quotes wastes time that could be spent on the job.
Roof work gets completed before the custom gutter arrives — leaving you with a callback install and an unhappy customer.
Trimgy gives gutter contractors and sheet metal fabricators a precision drawing tool to spec any gutter profile — and get it priced and ordered in minutes.
K-style, half-round, rectangular box gutter, custom commercial profiles — draw the exact cross-section using Trimgy's grid-constrained tool. Every leg and return snaps to 1/4-inch.
Choose aluminum (.027", .032", .040"), 24 ga. steel, Galvalume, or copper gauge equivalents. Color-coated options for commercial curb appeal. Pricing updates instantly.
Enter your total linear footage. Material cost and LTL freight to your job zip code are calculated together — so your landed cost is known before you click order.
Approve the price, check out with Stripe. Your exact gutter profile drawing goes to fabrication — no re-entry, no re-interpretation.
Save your standard K-style or box gutter profile. For repeat customers or similar projects, just change the footage and reorder — zero re-drawing.
Describe the gutter in plain English — "5-inch K-style, .032 aluminum, with 1/2-inch back hem" — and let AI draft the profile for you to confirm and order.
From light commercial K-style to large commercial box gutters and scuppers, Trimgy handles any gutter cross-section definable in straight-line segments.

Trimgy supports any brake-formed gutter profile that can be defined by straight-line segments: K-style (OG) gutters in 4-inch, 5-inch, and 6-inch widths; box gutters (rectangular gutters built into a roof structure); scuppers; and custom commercial gutter profiles. Half-round gutters require roll-forming and cannot be produced via brake forming — those must be sourced from a roll-forming supplier. Downspouts and rectangular conductor pipe can also be drawn and ordered.
SMACNA recommends a minimum of 26 ga. steel or .032" aluminum for light commercial gutters and 24 ga. steel or .040" aluminum for commercial gutters. For longevity, Galvalume (AZ50) provides superior corrosion resistance over standard G90 galvanized in most climates. Where color matching is important, Kynar-painted Galvalume is the commercial standard. Aluminum gutters are preferred in coastal climates due to their salt-air resistance.
K-style (ogee) gutters are the most common light commercial gutter profile — they have a flat back, flat bottom, and decorative S-curved front profile that resembles crown molding. Box gutters are rectangular in cross-section and are typically built into the structure of a roof (internal box gutters) or hung as large commercial gutters. Box gutters are common on older commercial buildings and are typically 8–24 inches wide. K-style gutters hang on the exterior fascia; box gutters require a more complex installation.
Yes. Trimgy's brake-forming process has no restriction on profile width within the machine's capacity (typically up to 10–16 feet of developed width per bend). You can specify a commercial K-style or box gutter in any width by drawing the exact cross-section profile and entering the dimensions. This is useful for replacing historic or oversized gutters that don't match standard 5-inch or 6-inch stock profiles available from gutter suppliers.
