All-U & All-V Metal Roofing Profiles (Auburn–Opelika)
Looking for the **tight, repetitive corrugated look**—either all-V (e.g., Taylor Metal Products ZigZag™) or all-U style? Here’s how those compare to common Alabama panels like Classic/AG rib, standing seam, 5V-crimp, and 7.2 trapezoid. We install across Auburn, Opelika, and nearby communities and can source specialty profiles when available.

All-U / All-V Metal Roof Profile Example Images
Featured: Taylor Metal Products ZigZag™ (All-V's)
- Look: tight, shallow V’s repeating across the sheet—very clean, modern corrugated aesthetic.
- Use: often specified on architecturally styled projects; more common in the Pacific Northwest market. Availability in Alabama varies—lead time and freight may apply.
- Install: verify minimum slope, use butyl tape at side laps, stitch screws (≈12" o.c. typical; confirm with data sheet), generous end-lap with sealant, and correct closures at eave/ridge.
- Structure: shallow micro-ribs are less stiff than 7.2/AG; expect **closer purlin spacing**. Ask for span tables.
All-U Corrugated (Micro-Rib / Mini-Corrugation)
All-U (small rounded corrugations) gives a classic corrugated look with a slightly softer profile than V. Similar install considerations: slope limits, sealants, stitch screws, and closures. Structural capacity is profile-dependent; request span/deflection tables for your gauge and spacing.
How They Compare (Practical)
| Profile | Minimum Slope & Water | Stiffness / Spans | Fasteners | Where It Shines |
|---|---|---|---|---|
| All-V (e.g., ZigZag™) | Needs steeper slopes; side-lap sealant + stitch screws. Avoid very low slope. | Lower; plan closer purlins. Check span tables. | Exposed fasteners + stitch screws at laps; butyl. | Modern corrugated aesthetic; architectural accents and steep roofs. |
| All-U (micro-corrugated) | Similar to All-V: steeper is better; seal laps carefully. | Lower to moderate; verify spans by gauge. | Exposed fasteners + stitch screws; closures required. | Classic corrugated vibe with tighter rhythm; barns to boutiques. |
| 5V-Crimp | Better hydro head than micro-corrugation; still not for low-slope. | Moderate; common coastal/Ag look. | Exposed fasteners; simple details. | Historic/coastal look with fewer deep V’s. |
| 7.2 Panel | Good water performance at appropriate slopes. | High stiffness; wide spans feasible. | Exposed fasteners; robust profile. | Industrial/modern “faceted” look; great structural value. |
| Standing Seam | Best for low slopes (per system); concealed clips; no through-fasteners on flats. | High; engineering options for wind/uplift. | Concealed clips/fasteners; optional striations. | Premium performance, clean lines, long life, fewer leak paths. |
Sourcing in Alabama (What We Typically Do)
- Local mills: A&E Metal, AL Steel (Montgomery) – ask about **mini-V / micro-corrugated** runs and lead times.
- National brands near you: McElroy Metal, Metal Sales, MBCI – often stock 7.2, AG/Classic Rib, 5V-crimp, and multiple standing seam systems; some can source architectural micro-corrugations.
- Architectural intent, performance needed: we can spec **standing seam with micro-rib striations** in the flats—captures the tight-rib look while keeping top-tier water/wind performance.
Details That Make or Break These Panels
- Sealants & laps: continuous butyl at side/end laps; stitch screws on a schedule (e.g., 12" o.c.—use manufacturer’s detail).
- Closures: profiled closures at eave/ridge; if none are stocked, we field-fit foam to match the micro-rib.
- Purlin spacing: micro-corrugations typically need tighter spacing; verify spans for your gauge/loads.
- Slope: these are not low-slope systems. For low slope, go standing seam or a PVC/TPO membrane.
- Coatings: PVDF/Kynar for best fade/chalk resistance in Alabama sun.
