Exposed-Fastener Panels
2.67 x .5 Corrugated Metal Panel: The Classic Half-Inch Wave
The 2.67 x .5 corrugated metal panel is the shallowest, most traditional profile we offer. Its rounded half-inch wave repeats every 2.67 inches, giving the soft ripple people picture when they hear “tin roof.” Pick it for porches, wainscot and farmhouse character rather than long, heavy spans.

| Specification | Typical value |
|---|---|
| Corrugation pitch | 2.67 in. from crest to crest |
| Corrugation depth | 1/2 in. |
| Overall sheet width | About 41-1/4 in. |
| Net coverage | About 37-1/3 in. on roofs, 40 in. on walls |
| Gauges and materials | Typically 26 or 24 gauge Galvalume steel; aluminum on request |
| Finishes | PVDF (Kynar 500), crinkle and Tedlar listed for this profile; SMP for budget work |
| Fasteners | Exposed self-drilling screws with sealing washers |
| Minimum roof slope | Typically 3/12 |
| Roof or wall use | Both; strongest on walls, porches and short roof runs |

What Sets the Half-Inch Wave Apart From Its Siblings?
Depth. At 1/2 inch, this wave is a little over half as deep as the 7/8 corrugated panel. That keeps the sheet light and wide, but it also makes it the least stiff profile in the family.
In practice, that means tighter purlin or batten spacing on roofs. It also means the panel looks its best at eye level, where the fine ripple reads as texture.
On a tall commercial wall, the deeper 7/8 corrugated panel holds a flatter, crisper line. Next to PBR, the half-inch wave looks softer and more traditional, while PBR spans farther on big barn roofs.
When Is This Corrugated Roofing Panel the Right Call?
Choose it when the look matters and the spans are modest. These are the jobs where it shines around Dallas-Fort Worth.
- A porch, patio or carport roof on a house with a different main roof.
- Wainscot or accent bands on a barndominium, shop or modern farmhouse.
- Small barns, chicken coops, pump houses and garden sheds on acreage.
- Interior accent walls and ceilings in shops, offices and restaurants.
- Re-skinning an older corrugated building with a matching half-inch profile.
It is the wrong call for long, low-slope roofs or for the main roof of a home in an HOA neighborhood. For those, compare standing seam, which hides its fasteners and moves freely on clips.
Installation Notes From Our Crews
Screw depth matters most on a thin profile. An overdriven screw dimples the steel and crushes the washer, so we set each driver to stop when the washer just bulges at its edge.
- Roofs use a wider side lap than walls, which is why roof coverage is narrower.
- Laps face away from the prevailing wind on the site to keep rain out.
- Butyl tape seals end laps and any side laps on lower-slope roofs.
- Half-inch foam closures seal the wave at eaves and ridges against pests.
- Over a deck, we lay high-temperature underlayment; over open purlins, a vapor retarder.
Be ready for routine upkeep. Like every exposed-fastener panel, this one needs a yearly screw check, because Texas UV ages the rubber washers. First replacements typically come after roughly 10 to 15 years, as our exposed-fastener panel guide explains.

2.67 x .5 Corrugated Panel Questions
What does 2.67 x .5 mean on a corrugated panel?
The first number is the pitch, the distance from one corrugation crest to the next, which is 2.67 inches. The second is the depth of each wave, half an inch. Our deeper 2.67 x .875 panel keeps the same pitch with a 7/8-inch wave.
Is 1/2 inch corrugated metal strong enough for a roof?
Yes, for porches, sheds and small outbuildings on closely spaced purlins or a solid deck. For long spans or large roofs, a deeper profile such as 7/8 corrugated or PBR bridges wider purlin spacing. Your shop drawing and the manufacturer’s load table set the spacing.
Can I use this corrugated panel as siding?
Yes. It is a common wall and wainscot panel, usually run vertically. Wall coverage is slightly wider than roof coverage because walls need less side lap. We bend the matching corner, base and window trim in our shop.
Which gauge should I choose for half-inch corrugated?
26 gauge suits most porch roofs, sheds and wainscot. Step up to 24 gauge for better dent resistance where hail is frequent or where equipment may bump a wall. A 24-gauge sheet is roughly 28 percent thicker than 26 gauge.
