Using 29 gauge panels in a 120 mph hurricane zone will fail code inspections and void the warranty. Check your local wind load requirements before locking in a gauge — going from 29 to 24 gauge adds roughly $1–$2/sq ft but is non-negotiable in Dade County FL or coastal TX.
Standard: 16″ OC, 1.5 screws/sq ft. Hurricane zone: 12″ OC, 3 screws/sq ft. Standing seam with concealed clips: 1 clip every 12″ per panel side. Forgetting hurricane spec spacing is the #1 pole barn structural inspection failure in Florida and the Gulf Coast.
Metal Siding Parameter Matrix
Every parameter of every metal siding profile — coverage, gauge, waste, cost, and unique behavior. The numbers behind the terminal configurator above.
| Profile | Coverage | Waste | Gauge | Cost |
|---|---|---|---|---|
| Corrugated Metal | 240 sq ft | 8–10% | 29 gauge | $4–$7 |
| Ribbed Metal | 210 sq ft | 8–10% | 29 gauge | $4–$8 |
| Standing Seam | 300 sq ft | 10–12% | 22–24 gauge | $8–$15 |
| Steel Lap Siding | 200 sq ft | 10% | 26 gauge | $5–$10 |
| Aluminum Soffit | 120 sq ft | 5–8% | 0.019–0.024″ | $2–$4 |
Frequently Asked Metal Siding Questions
How many screws per square foot of metal siding?▼
Standard corrugated metal uses about 1.5 screws per square foot — two screws per panel overlap seam, one per edge. Hurricane zones double this to 3 screws per sq ft. For standing seam with concealed clips, you need one clip every 12–16 inches along each panel side.
What gauge metal siding should I use?▼
29 gauge is the lightest and most economical — fine for pole barns, utility sheds, and low-wind areas. 26 gauge is residential-grade and meets most building codes. 22–24 gauge standing seam is premium, rigid enough for vertical walls and high-wind hurricane zones.
Does metal siding rust?▼
Galvanized steel (G90 minimum) resists rust for 20–30 years, but scratches and cut edges are vulnerable. Aluminum never rusts but is more expensive. Premium metal siding uses PVDF or SMP paint systems that last 30+ years without fading or chalking.
How do I calculate metal siding for a pole barn?▼
Pole barn wall area = 2 × (width + length) × wall height. A 40′ × 60′ barn with 12′ walls needs 2 × 100 × 12 = 2,400 sq ft of siding. Add gables if present: gable area per end = base × peak ÷ 2. Use our pole barn toggle above for automatic calculation.
Can metal siding be installed vertically?▼
Yes — vertical metal siding installs with the same profiles but runs panels top-to-bottom instead of left-to-right. Coverage is identical per panel, but layout changes: vertical panels need more flashing at top/bottom edges, and you typically need 15% extra waste for cutting around windows horizontally.
