Aluminum Trim & Coil
About Aluminum Trim & Coil
Aluminum trim coil is the material behind every clean fascia wrap, window cap, and custom brake-formed profile on a professional siding installation - and the colour match between your coil and your siding is the detail homeowners notice and contractors get credit for.

Available in 24" and 50" widths at residential (0.019") and commercial (0.024") gauges - everything your crew needs from the coil to the downspout to the elbow, sourced from one colour-coordinated system.

Key factors to evaluate when specifying aluminum trim & coil for your project.
Aluminum Trim Coil Specification Guide
Gauge selection
Mitten's standard residential fascia coil is 0.019" - the right gauge for most residential window and door trim wraps. For fascia boards wider than 8" or in high-wind locations, specify 0.024". Commercial applications typically use 0.027"–0.032".
Width
Coil comes in 24" and 50" widths. 24" coil handles most residential fascia, window and door trim wraps, and narrow soffit profiles. 50" wide coil is used for wide fascia boards, large soffit panels, and custom millwork applications. Calculate the flat developed length of your widest profile before ordering coil width.
Colour selection
Mitten's 13-colour trim coil palette is coordinated to their siding lines, making it straightforward to specify matching fascia, window trim, and siding from a single colour system. White is the most popular choice for contrast against any siding colour. Almond, Clay, and Autumn Woodgrain are popular for warm-toned siding systems.
Gutter coil
Mitten's gutter coil is specifically formulated for roll-formed eavestrough fabrication - heavier gauge, tested for water contact, and colour-matched to the trim coil palette. Specify gutter coil (not trim coil) for any eavestrough application.
Accessories
Mitten's aluminum line includes pre-formed downspouts, elbows, and end caps in matching colours. Sourcing downspouts from the same manufacturer as your eavestrough system ensures colour match and system compatibility.
Frequently Asked Questions
What is the difference between trim coil and soffit?
Trim coil (also called coil stock or fascia coil) is flat aluminum coil stock that is field-formed by a brake press into custom profiles - fascia wraps, window sills, drip caps, etc. Soffit is a pre-finished panel product with a formed profile (flat, vented, or beaded) specifically designed to cover the eave underside. Both are aluminum products, but soffit comes as finished panels while coil stock is raw flat material for custom brake work.
Can I use trim coil to fabricate custom eavestroughs?
No - standard trim coil is not suitable for eavestrough fabrication. Use Mitten gutter coil, which is heavier gauge and specifically tested for water channel applications. Using trim coil for gutters risks premature failure and voiding any applicable warranty.
How do I match Mitten aluminum trim coil to their vinyl siding?
Mitten produces coordinated colour charts showing exact trim coil colours matched to each vinyl siding line. White trim coil (001) matches all Mitten siding lines and is the safe default. For colour-matched fascia and trim, cross-reference the siding colour code to the Mitten trim coil colour chart - available from our sales team. We stock all 13 Mitten trim coil colours.
