Painted aluminum is supplied as coil, cut-to-length sheet, and finished sign blanks. Coil suits high-volume roll forming, sheet is the standard format for fabrication and panels, and sign blanks are pre-cut sheets sized for signage. Cut-to-length lines let you order custom lengths and widths within the coil’s range, so you can match the format to your process and reduce waste.
What forms does painted aluminum come in?
| Format | Description | Best for |
|---|---|---|
| Coil | Continuous rolled aluminum, painted on a coil line | Roll forming, high-volume runs, custom cut-to-length |
| Sheet | Flat, cut-to-length panels | Fabrication, wall and roof panels, general use |
| Sign blanks | Pre-cut sheets sized for signs | Signage, wayfinding, channel letters |
What sizes are available?
Sheet and coil come in a range of widths and thicknesses, with gauges commonly from .020 to .080. Cut-to-length lines produce custom lengths from coil, so you can specify a size that fits your panels and cuts down on scrap. Sign blanks are offered in standard signage dimensions and custom sizes on request.
How do you choose coil vs sheet vs sign blanks?
- Coil: choose it for roll forming or when you run large volumes and want to cut your own lengths.
- Sheet: choose it for shop fabrication and panel work where flat stock is easiest to handle.
- Sign blanks: choose them when you want ready-to-use, pre-sized signage material.
For signage specifics, see aluminum sign blanks, and for thickness selection see the painted aluminum gauge guide.
How do you order the right format?
Confirm coating (70% PVDF for exterior), color, gauge, and format, then provide finished dimensions so the supplier can cut to length. Wrisco manufactures in-house with computerized cut-to-length lines and stocks over 50 colors; order from the painted aluminum sheets page.

Are sign blanks just pre-cut sheets?
Essentially yes, sized and finished for signage so they are ready to use with minimal fabrication.
