Choosing the right plate...

Choose the best material for your project’s needs—Super•Cor or Bolt-A-Plate in galvanized or Best•Kote polymer-coated steel (+75 Year Design Service Life) or Dur•A•Span in solid aluminum. AIL Pre-Engineered Packaged Solutions are available as Arches, Box Culverts or Rounds in a variety of convenient sizes. 

Choose the size that best suits the hydraulic, live load, height of cover and soil chemistry requirements of your particular application. Professional site assessment is needed for potential hydraulic and frost impact on the structure.

Several Standard Plate Sizes Available
Structural Plate Sizes

Arches: spans up to 4.2 m

Standard Arches are well suited to a wide number of applications. They offer low clearances and wide-mouthed waterway openings for an optimum combination of strength and hydraulics.
In Galvanized Steel, Polymer-Coated Steel, Aluminum



Box Culverts: spans up to 7 m

Box Culverts are ideal when a very low structure is needed with a maximum waterway opening. They are ideal for short span bridge replacements, culverts and stream enclosures.
In Galvanized Steel, Polymer-Coated Steel



Rounds: diameters up to 4.2 m

Rounds function well in many applications, but are especially well suited to high cover projects. They are chosen for culverts, storm sewers, tunnels and stream enclosures.
