Super-Wal Dome Pre-cut Complete Shell Kit (Large Diameter Domes 56′ – 80′)

These domes are usually used for commercial, industrial or institutional structures requiring large free-span areas. However, they certainly can be used for very large residential projects requiring lots of space.

The Complete Shell Kits below include the following items for Super-Wal system:

Super-Lok connection hardware: Hubs, plated steel sleeves, plated bolts, nuts, pins. Sleeves are attached to struts.


Risers: Standard heights for high profile are 28 1/2”, for low profile 45”. 5 riser walls come pre-assembled with intermediate 2×4 studs @ 24” o.c. (the rest of the risers come with pre-assembled corner riser struts and pre-cut intermediate studs and plates.) 3/4” plywood is included for the exterior and attached on 5 riser walls.  All riser corners are 3×10 #1 DF with our Ultra-Lok sleeve.

Struts: 12” to 21” thick Super-Wal double strut with metal sleeves attached to select structural grade So. Yellow Pine 2×8. Inner 2×4 strut is attached to exterior 2×8 with three 3/4” thick 8” wide plywood gussets. If needed, 2×8 exterior struts are pre-notched for ventilation. 2×8 exterior struts are standard on all domes. 2×10 and 2×12 are available options.

Exterior Triangles: 3/4” plywood pre-cut triangles are 2-piece (Model 625 & Model 1250 have some 3-piece triangles). Joint between 2 pieces is tongue and grooved. 3″ galv. ring shank nails are provided for nailing panels @ 6″ O.C.


Vent System: Lower base vent drip edge is enameled aluminum. Top vent cupola has complete pentagonal frame pre-assembled with 3/4” plywood sheathing pre-cut. Includes aluminum drip edge, combination fascia/soffit vent, and aluminum base flashing between top vent cupola and shingle edge.

The Construction Manual includes complete installation instructions, and video/DVD for assembling the dome shell kit (It does not include floor plan layouts, joist framing plans, foundations and the like). Engineering certification of the dome shell is included if needed for the building inspector.

All structural shell items are color-coded or labeled for ease of assembly instruction.

Prices shown below include all items listed above, our owner-builder tool package, and our premium fastener/nail package, plastic plan cover, two T-shirts, 1/2” rope.

Engineering certification of the dome shell is not included due to the custom nature of these sizes. Most commercial/industrial projects require engineering of the complete project, which we can provide. All 6 frequency domes utilize our heavier duty Ultra-Lok connection hardware.

Options for all of our domes include fire treating the lumber to meet fire codes, heat treating the lumber to meet exporting criteria or using CCA treated lumber for termite protection. Contact us for other options to satisfy commercial building codes. Considerable customization is usually done so costs and specs will vary.

The model number of each dome below is the sq. ft. available on the main floor of that dome. Extension openings may vary in quantity from those shown below. Other diameter sizes are available. Call for more information.
