How much overlap do I need for corrugated panels
For most roofing and siding installs, overlap at least one full rib. In high-wind or heavy rain areas, additional sealing methods may be used depending on your project details. If you are unsure, contact us and we will help confirm a layout.

Are these panels used for roofing or mainly for siding and projects
These panels are commonly used for siding, fencing, raised beds, and utility structures. Many customers also use corrugated panels for roofing depending on slope, underlayment, fastening pattern, and flashing details. Verify your design and use proper trim, closures, and fasteners for your application.

Will these panels rust in Pacific Northwest rain
The aluminum-zinc coating is selected for strong corrosion resistance in wet climates. Like any steel product, long-term performance depends on proper installation, avoiding trapped debris, and preventing standing water at edges or cut areas.

Can I use these panels for raised garden beds
es, they are commonly used for raised beds and planters. They are not certified as food-grade. If you have specific soil or crop requirements, consider using a liner or barrier and follow your preferred gardening practices.
