Black corrugated metal is corrugated steel or aluminum sheet finished in a black color, and it sells in two clearly different grades that get confused constantly: roofing-grade panels (24 to 26 gauge, PVDF or SMP paint over Galvalume) built to last 40 years or more, and thin decorative panels (often 29 gauge painted galvanized) meant for siding, fencing, and accent walls. Matte black is the most common finish because it hides oil-canning and surface scratches better than a glossy black. The grade you buy, not just the color, decides whether the panel lasts decades or two seasons.
This guide separates the two grades, compares the black finishes by how they fade, lists the real dimensions and 2026 pricing, and covers the tradeoffs that black specifically brings to a roof or wall. For picking among every other color, see our full corrugated metal roof color palette. For black in standing seam and other profiles, see black metal roof panels in other profiles.
Black finishes compared: matte, gloss, and “black Galvalume”
Black corrugated metal comes in three finish families: matte black (low sheen PVDF), standard gloss black (SMP paint), and panels sold as “black Galvalume,” which almost always means black paint over a Galvalume substrate rather than a bare metallic black. The paint system, not the shade name, controls how long the black stays true. PVDF (Kynar 500) resists fade and chalking; SMP costs less but fades and chalks faster, which shows more on dark colors than light ones.
| Finish | Paint system | Sheen | Fade behavior on black | Typical paint warranty | Cost vs SMP |
|---|---|---|---|---|---|
| Matte black | PVDF (Kynar 500) | Low | Minimal fade, resists chalking | 30 to 40 years | +30% to 40% |
| Gloss / standard black | SMP (silicone-modified polyester) | Semi-gloss | Fades and chalks sooner, visible on dark tones | 25 to 30 years | Baseline |
| “Black Galvalume” | PVDF or SMP over Galvalume | Varies | Depends on the paint, not the substrate | Matches the paint | Varies |
| Powder-coated black (decorative) | Powder coat | Matte to satin | Chips at cut edges, best for light-duty and interior use | Limited | Varies |
Matte black hides two things gloss cannot: minor waviness in flat sections and hairline scratches from handling. That is why suppliers such as Western States Metal Roofing list matte black as “a softer and less drastic color than a typical black glossy roof.”
Panel specs: gauge, corrugation, and coverage width
The single spec that separates roofing-grade black corrugated metal from decorative panels is gauge. Roofing panels run 24 to 26 gauge steel over an AZ50 Galvalume substrate; decorative and light siding panels run 29 gauge painted galvanized or thin aluminum. A common 7/8 inch corrugated profile has a 2.67 inch rib pitch, an overall width near 39 inches, and a roof coverage width around 34.67 inches once panels overlap.
| Spec | Roofing grade | Decorative / light siding grade |
|---|---|---|
| Gauge | 24 to 26 ga steel | 29 ga galvanized or thin aluminum |
| Substrate | AZ50 Galvalume | G60 to G90 galvanized |
| Rib (corrugation) height | 7/8 in | 1/2 in to 7/8 in |
| Rib pitch | 2.67 in | ~2.5 in |
| Overall panel width | ~39 in | ~26 to 38 in |
| Roof coverage width | ~34.67 in | Varies, often not rated for roofing |
| Minimum roof slope | 3/12 | Not rated for roofing |
If a listing does not state gauge, substrate, and coverage width, treat it as decorative. Cheap black panels on marketplace listings are usually 29 gauge painted galvanized, fine for a coop wall or a fence, risky as a real roof.
Sizes: 8 ft, 10 ft, 12 ft, and cut-to-order
Stock black corrugated metal comes in 8, 10, and 12 foot lengths at big-box and marketplace sellers, while specialty suppliers cut panels from 1 foot to about 52 feet to your exact run. The 8 foot panel is the most common decorative size and typically covers about 2 feet of width after the sidelap, so plan on more panels than the raw width suggests.
- Measure the roof or wall area in square feet (length times width of the plane).
- Find the panel’s coverage width, not its overall width. A 39 inch panel covers about 34.67 inches; a 26 inch decorative panel covers roughly 24 inches.
- Divide the plane width by the coverage width to get panels per row, then round up.
- Add 10 percent for waste, cuts, and overlap on hips or valleys.
Worked example: a 10 by 12 foot shed roof plane (120 square feet) using 8 foot panels that cover 2 feet each needs 6 panels per 12 foot row, one row of 10 foot panels or 8 foot panels run vertically, plus the 10 percent waste factor. Confirm the exact coverage on the spec sheet before ordering.
How much black corrugated metal costs in 2026
Black corrugated metal ranges from about $18 for a single decorative 29 gauge panel to $3.50 per square foot for 24 gauge matte black PVDF material, before labor. Installed on a roof, expect roughly $8 to $14 per square foot including tear-off, fasteners, and trim. Black itself adds little to material cost; the paint system (PVDF vs SMP) and gauge drive the price more than the color.
| Item | Typical 2026 price |
|---|---|
| Decorative 29 ga painted panel (marketplace or box store) | $18 to $35 each |
| Roofing 26 ga SMP black, material only | $2.00 to $2.50 / sq ft |
| Roofing 24 ga PVDF matte black, material only | $2.50 to $3.50 / sq ft |
| 8 ft matte black panel (about 2 ft coverage) | $32 to $55 each |
| Installed on a roof, all-in | $8 to $14 / sq ft |

Roofing, siding, fencing, or accent wall: which grade fits
Match the grade to the job, because the same black corrugated look spans a real roof and a decorative fence. Roofing needs 24 to 26 gauge Galvalume with a proper paint warranty and a 3/12 minimum slope; siding and interior accents can use lighter panels because they are not shedding standing water or bearing snow load.
- Roofing: 24 to 26 ga, AZ50 Galvalume, PVDF or premium SMP, bead mastic at overlaps, 3/12 or steeper.
- Exterior siding and fencing: 26 to 29 ga; galvanized is acceptable on vertical walls where water sheds fast, but cut edges still need attention.
- Accent walls, ceilings, bar fronts, kitchen islands: 29 ga or thin aluminum is fine; powder-coated black works indoors.

The tradeoffs black brings: heat, fade, scratches, and oil-canning
Black corrugated metal carries four honest downsides that product listings rarely spell out: it absorbs more solar heat, dark tones show fade sooner, black paint reveals scuffs, and flat sections can oil-can. None of these rule it out, but each has a fix worth knowing before you commit a full roof or wall to black.
- Heat: black absorbs more solar energy than light colors and can run hotter, though a cool-roof matte black with reflective pigments narrows the gap. Adequate ventilation and a radiant-barrier or high-temp underlayment matter more on dark roofs.
- Fade: fade and chalking are more visible on dark colors, so the PVDF vs SMP choice matters most on black. On siding, fade shows fastest on south and west walls.
- Scratches and cut edges: black shows handling scuffs, and bare cut edges can rust on galvanized panels. Galvalume resists edge creep better; touch-up paint on field cuts helps either way.
- Oil-canning: waviness in flat metal is more obvious in gloss black. Corrugation hides it better than standing seam, and matte hides it better than gloss.
Where to buy and how to avoid the cheap-panel trap
Black corrugated metal is stocked by Western States Metal Roofing, Home Depot, Lowe’s, and marketplace sellers such as BarrierBoss and Steeldash, but the listings mix roofing panels and decorative panels under the same “black corrugated” name. The trap is buying a thin painted galvanized panel for a roof and watching it fade and rust at the cuts within a few seasons.
- Confirm the gauge and substrate. For a roof, require 24 to 26 gauge over AZ50 Galvalume.
- Check the paint system and warranty. PVDF (Kynar 500) with a 30-year-plus finish warranty for exposed black; treat unwarranted paint as decorative.
- Read the coverage width, not the overall width, so your panel count is right.
- Ask about cut-to-length. Ordering exact lengths removes end laps, a common leak point on roofs.
- Order matching trim, closures, and mastic in the same finish; mismatched black trim is a giveaway of a rushed job.
The same terminology confusion shows up with “tin,” which is neither tin nor a grade; see what a corrugated tin roof really is.
Frequently asked questions
Does black corrugated metal fade?
Black corrugated metal can fade, and dark colors show fade and chalking more than light ones. The paint system decides how fast. PVDF (Kynar 500) finishes resist fade and chalking and carry 30 to 40 year warranties, while cheaper SMP paint fades sooner, often visibly on black within 10 to 15 years. Bare or unwarranted painted panels fade fastest.
Is a black metal roof hotter?
A standard black metal roof absorbs more solar heat than a light-colored roof and can run hotter at the surface. Cool-roof matte black panels use reflective pigments to reduce that gain, and proper attic ventilation plus a radiant barrier or high-temp underlayment limit how much heat reaches the living space. The difference is real but manageable with the right assembly.
What gauge black corrugated metal do I need for a roof?
For a roof, use 24 to 26 gauge black corrugated panels over an AZ50 Galvalume substrate, installed at a 3/12 slope or steeper with bead mastic at overlaps. The 29 gauge painted galvanized panels sold cheaply online are decorative grade, suited to siding, fencing, and accent walls, not to shedding standing water or carrying snow load on a roof.
Can you use black corrugated metal for siding?
Yes. Black corrugated metal is widely used for siding, privacy fencing, covered patios, carports, bar fronts, and interior accent walls. Vertical walls shed water quickly, so lighter 26 to 29 gauge panels are acceptable there, though cut edges still benefit from touch-up on galvanized stock. Match trim and closures to the panel finish for a clean result.
What is the difference between matte black and “black Galvalume”?
Matte black is a low-sheen paint color, usually PVDF, applied over a metal substrate. “Black Galvalume” is a marketing name for black paint over a Galvalume-coated steel sheet; the Galvalume is the corrosion-resistant metallic coating underneath, not the black itself. In practice both are painted panels, so compare the paint system and warranty rather than the name.
How much does an 8 ft black corrugated metal panel cost?
An 8 foot black corrugated panel runs about $18 to $35 for a 29 gauge decorative panel and roughly $32 to $55 for a 24 gauge matte black PVDF panel, before shipping. Each 8 foot panel typically covers about 2 feet of width after the sidelap, so budget for more panels than the raw width suggests.
