Aluminum coil is one of the most versatile flat-rolled metal products on the market. Contractors roll it into seamless gutters on-site. Sign fabricators slit it into channel letter strips. Builders wrap it around fascia boards and window frames. Roofers press it into flashing profiles. Whatever form it takes at the end of the line, every application starts with the same foundation: a high-quality aluminum coil that holds precise dimensions, accepts paint and coatings cleanly, and stays flat through forming without cracking or spring-back.
This page covers the full range of aluminum coil products we supply — trim coil, gutter coil, painted coil, channel letter coil, roofing coil, anodized coil, and standard mill-finish stock — with complete specifications, alloy options, and application guidance.
Aluminum Trim Coil: Pre-Painted and Ready to Form
Aluminum trim coil is the workhorse of residential exterior finishing. Contractors use it to cap fascia boards, wrap window surrounds, cover soffits, and protect any wood exterior surface from weathering. Our trim coil ships in standard widths from 24 inches to 48 inches, with custom widths available on request.

Gutter coil stock moves in high volume to roofing contractors, gutter specialists, and lumber yards in the continental United States — particularly the Midwest, Southeast, and Pacific Northwest where freeze-thaw cycles make aluminum’s corrosion resistance non-negotiable. Eavestrough aluminum coil (the Canadian term for the same product) ships regularly to Ontario, British Columbia, and Quebec.
For 5-inch K-style gutter systems, 0.027″ thickness in 3105-H25 is the most common spec. Six-inch systems typically run at 0.032″ for extra rigidity. Gutter coil prices fluctuate with LME aluminum — our team provides weekly pricing updates to active accounts.
Painted Aluminum Coil: Color Coated Coil for Architecture and Cladding
Painted aluminum coil — also called pre-painted or color coated aluminum coil — covers applications where the coil’s finished surface becomes the visible exterior of a building panel, fascia system, or curtain wall component.
We supply two main coating systems:
PVDF (Polyvinylidene Fluoride / Kynar 500®)
- Designed for exterior architectural applications
- 20–30 year color retention without significant fade or chalk
- UV resistance rated for the harshest sun exposures
- Standard coating thickness: 25 microns (topcoat) + 5–8 microns (primer)
- Ideal for curtain wall panels, composite panels, standing seam roofing
SMP (Silicon-Modified Polyester)
- Cost-effective option for moderate exposure conditions
- Good flexibility and impact resistance
- Standard coating thickness: 20 microns topcoat

Aluminum Channel Letter Coil: Thin-Gauge Strip for Sign Fabrication
Channel letter coil is a narrow-gauge, high-purity aluminum coil that feeds the routing and bending machines in sign shops to produce the three-dimensional illuminated letters used in retail storefronts, mall directories, and corporate identity systems.
Channel Letter Coil Specifications
| Parameter | Specification |
|---|---|
| Alloy | 1100, 3003 |
| Temper | H14, H18 |
| Thickness | 0.4mm – 1.0mm |
| Width | 75mm – 610mm |
| Surface | Mill finish, painted white, painted black |
| Coil Weight | 25 kg – 100 kg (small spools) |
| Tensile Strength | 95 MPa (1100-H14) – 145 MPa (3003-H18) |
| Bend Radius | Down to 3x material thickness without cracking |
The thin-gauge, high-ductility profile of channel letter aluminum coil handles tight radius bends that thicker alloys can’t manage without cracking. Sign fabricators in the US, Canada, the UAE, Australia, and the UK consume large volumes of 1100-H14 and 3003-H14 strip for letter returns and backs. Aluminum strip for channel letter applications typically runs between 76mm and 150mm wide, matching the standard return depth for 3-inch to 6-inch letter faces.
Aluminum Roofing Coil and Flashing Coil
Aluminum roofing coil covers a wide range of applications — standing seam roofing profiles, through-wall flashing, step flashing, valley flashing, drip edge, and gravel stop. Its corrosion resistance without any surface coating makes it the preferred metal in coastal environments where steel rusts quickly.
Roofing and Flashing Coil Specifications
| Parameter | Specification |
|---|---|
| Alloy | 3003, 3105, 1100 |
| Temper | H14, H16, H25 |
| Thickness | 0.016″ – 0.040″ |
| Width | 6″ – 36″ standard |
| Coil Weight | 25 lb – 100 lb |
| Surface | Mill finish or pre-painted |
| Hardness | H14 or H25 for optimal formability |
Aluminum flashing coil in 0.019″ and 0.024″ thickness handles most residential flashing applications. Commercial roofing contractors running standing seam systems prefer 0.032″ or 0.040″ in pre-painted PVDF finish for maximum weather resistance and visual consistency.
Aluminum trailer roof coil — a related product used in the truck and trailer manufacturing industry — typically runs at 0.040″ to 0.050″ in 3003-H14, providing the strength needed to span roof bows without visible deflection.
Anodized Aluminum Coil: Architectural and Industrial Finishing
Anodized aluminum coil undergoes an electrochemical process that converts the surface layer into a hard, durable aluminum oxide film. Unlike paint, anodize becomes part of the metal itself — it doesn’t peel, chip, or crack with normal forming and handling.
Anodized Coil Specifications
| Parameter | Specification |
|---|---|
| Base Alloy | 1100, 3003, 5052, 5005 |
| Temper | H14, H18, H24 |
| Anodize Thickness | Class 1: 0.7 mil (18 microns) / Class 2: 0.4 mil (10 microns) |
| Colors | Clear/silver, champagne, light bronze, medium bronze, dark bronze, black |
| Gloss | Matte to satin |
| Width | 50mm – 1,600mm |
| Thickness | 0.3mm – 3.0mm |
| Hardness (surface) | 250–350 HV |
Anodized aluminum coil suits applications where the metal surface stays visible in the finished product — architectural trim, solar panel frames, LED lighting housings, electronics enclosures, and automotive interior trim. The hard oxide layer handles abrasion better than most organic coatings and maintains appearance through decades of exposure in urban environments.
Aluminum Coil Pricing: What Buyers Should Know
Aluminum coil price ties directly to the London Metal Exchange (LME) aluminum benchmark, which changes daily. On top of the LME base, buyers pay a fabrication premium (also called conversion premium) that covers rolling, annealing, slitting, and coating operations.
