This table presents the various shapes, geometries and the range of sizes of corrugated steel drainage products (pipe, pipe arch and plate).
| Shapes and uses of corrugated conduits | |||
| Shape | Range of Sizes | Common Uses | |
| Round |  | 6 in. -51 ft | Culverts, subdrains, sewers, service tunnels, etc. All plates same radius. For medium and high fill (or trenches) |
| Vertical ellipse 5% nominal |  | 4-21 ft nominal;before elongating | Culverts, sewers, service tunnels, recovery tunnels. Plates of varying radii;shop favbrication. For appearance and hwhere backfill compaction is only moderate. |
| Pipe Arch |  | Span x Rise 17 in, x 13 in. to 20ft 7 in x 13 ft 2 in. | Where headroom is limited, Has hydraulic advantages at low flows. Corner plate radius. 18 inches or 31 inches for structural plate. |
| Underpass* |  | Span x Rise 5ft 8 in, x 5 ft 9 in. to 20 ft 4 in. x 17 ft 9 in. | For pedestrians, livestock or vehicles (structural plate). |
| Arch |  | Span x Rise 5 ft x 1 ft 9 1/2 in. to 82 ft x 42 ft | For low clearance large waterwway openinng, and aesthetics (structural plate). |
| Horizontal Ellipse |  | Span 7-40 ft | Culverts, grade separations, sorm sewers, tunnels (structural plate). |
| Pear |  | Span 25-30 ft | Grade separations, culverts, storm sewer, tunnels (structural plate). |
| High Profile Arch |  | Span 25-83 ft | Culverts, grade separations, storm sewers and tunnels. Ammunition magazines, earth covered storage (structural plate). |
| Low Profile Arch |  | Span 20-83 ft | Low-wide waterway enclosures, culverts, storm sewers (structural plate). |
| Box Culvert |  | Span 10-53 ft | Low-wide waterway enclosures, culverts, storm sewers (structural plate). |
| Specials | Various | For lining old structures or other spcial puposes. Special fabrication. | |
| Notes: *For equal area or clearance, the round shape is generally more economical and easier to assemble. | |||
