Prefab tunnel arches for Viking-style underground builds, priced per arch.
2x2 14-gauge galvanized square tube arches, about 12 ft wide (144 in outside), 32.5 in straight legs, set 2 ft on center. Each arch is cut at the center for shipping and bolts together on site.
Finished size is about 12 ft wide and about 9 ft tall at the peak. We offer arches up to 12 ft wide; for anything wider we recommend our Quonset method.
How many you need depends on length. For example, a 40 ft tunnel takes about 21 arches.
Ships in about 6 weeks from order, delivered to your site. Freight is quoted at order, since it depends on your location.
Roof steel is not included. You'll buy 24-gauge high-rib roof panels locally (36 in coverage, 1-1/2 in deep ribs on a 7.2 in pattern, such as NuRay NRM-7000), and we can help you find a supplier near you. Dave runs the panels painted side down so the color shows inside.
Preliminary drawings and DIY guidance. Final design must be reviewed and stamped by a licensed engineer for your site and state. The builder is responsible for site conditions, permits and code compliance.
Price is per arch. Shipping is not included and is quoted to your state when you order.
