Our Commitment Atlantic Industries Limited (AIL) has built a solid reputation by providing professional support and innovative, high-quality corrugated metal products around the world.

Lightweight, strong and corrosion/abrasion resistant, AIL’s Dur•A•Span Aluminium Structural Plate has been going the distance in over 1,000 structures worldwide for many years – beating the usual heavyweight contenders, like precast concrete, on overall performance and cost. And now, thanks to our innovative reinforcing rib technology, Dur•A•Span can go even farther (and wider) to outperform all challengers. The proven strength, economy and longevity of Dur•A•Span is ideal for coastal or remote installations. Corrosion/Abrasion Resistant Aluminium is well-known for its longer design service life....

All in a day’s work and no heavy lifting! Many Dur•A•Span™ structures can be shipped assembled and be set in position the same day with a medium duty crane or an excavator. In this case, the headwalls were attached on arrival and, at the end of the day, everything was in position and engineered backfilling had begun.

Light, Strong and Durable by Design. Ever notice how it’s only this type of shell that survives the pounding surf? Like the shell, Dur•A•Span™ structures are designed to withstand the harshest corrosive and abrasive coastal environments to outlast all others. Dur•A•Span versus Concrete Weight 1/50 the weight of concrete pipe Faster, easier to install than concrete, less labour and trucking costs Site Impact Minimal with aluminium, lighter (lower cost) equipment, less excavating Very low, easy to inspect, continuous footings eliminate settling Corrosion/abrasion resistant and mechanical joints...
