We Support You.Atlantic Industries Limited (AIL) has built a solid reputation delivering

proessional support and innovative, high-quality, corrugated metalproducts around the world.

Atlantic Industries Limited has a long history o creating innovative solutions incorrugated steel. Since 1965, AIL has been engineering high-quality, durable corrugatedsteel products or major industries like transportation, hydro, mining and orestry. oday,the AIL Group o Companies is well poised to serve you through several locations inNorth America, Australia, Europe and Asia. Our solutions come in a variety o sizes,ranging rom culverts and sewers to tunnels, bridges, underpasses and stream enclosures.

Our reputation has been orged not only on the success o our competitively pricedproducts, but also through the innovative engineering and reliable service we provide toour customers. AILs worldwide support includes project management, problem solvingand eld service. In keeping with AILs ongoing commitment to high standards, our HeadOfce Plant in Dorchester, New Brunswick and our Engineering Department in Ayr,Ontario have been certied to ISO 9001:2000.

Trough our ongoing research and development programs, our engineers have oundoptimum solutions using our innovative Super Cor corrugated steel. We recommend thatbeore you speciy any o our SuperCor products, take the opportunity to consult with an

AIL technical representative or advice and assistance on your project.

SuperCor

As AILs revolutionary alternative to conventional bridges,SuperCor represents our commitment to continued

development in the ield o corrugated metal structures.

Superior Strength. Lightweight Construction.SuperCors larger annular corrugations (381mm [15"] pitchand 140mm [5.5"] depth) provide nine times the stiness o

conventional structural plate. he lightweight, modular panelscan be shipped easily and economically making it even moreadvantageous or remote locations.

Easy InstallationSimply put, SuperCor saves time and money in installation. hepanels require signiicantly ewer bolts than conventional structuralplates and can be assembled adjacent to the job site, then movedinto place using relatively light equipment. And, i the road needsto be widened later, SuperCor allows or easy extension withadditional panels.

The sensible,economical choice or:

Vehicle underpasses Bridges

Railway underpasses

Box culverts

Underground storage

Stream enclosures/crossings

Storage magazines

Wildlife underpasses

Mine portals

Combining the advantages o lightweight construction with the superior strength and durability o galvanizedsteel, SuperCor is the most internationally accepted, and widely used corrugation proile on the market.

Mining companies take advantage o AILs technology to buildsome o the largest and most economical bridges in remotelocations, such as this one in Australia.

IDEAL FORREMOTE LOCATIONS

VersatileSuper Cors corrugation proile permits constructiono the largest, longest and widest spans in a varietyo conigurations. Spans can exceed 25m (82') with

AILs proprietary eatures. Special shapes are alsoavailable, including SuperCor reinorced boxculverts in spans exceeding 15m (50') with cover asshallow as 450mm (18").

DurableSuper Cors heavy galvanized coating ismetallurgically-bonded to the steel surace, providingextended service lie. SuperCor is supplied witha standard 915g/m2 (3oz/t2) coating. A heavier1220g/m2 (4 oz/t2) coating is also available. Properlydesigned and installed, SuperCor structures will lastover 100 years. Co-Polymer coatings are also availableto urther extend service lie.

Environmentally-ResponsibleMost SuperCor structures used or stream crossingsare bottomless. hese structure types, combined withlower-impact installation methods, virtually eliminatedeliberate streambed intererence.

Maintenance-Free

Unlike conventional bridges, which requently requiresubstantial retroits, properly-installed SuperCorstructures are relatively maintenance-ree.

Aesthetically-PleasingOnce installed, SuperCor becomes a naturally-appealing structure. he geometry o the corrugationsboth sotens and reduces the intrusivenesstraditionally associated with man-made structures innatural environments.

SuperCorRound

SuperCor Round structures permitconstruction o dramatically larger diameters

than was previously possible with conventionalstructural plate pipe conigurations.

SuperCor is the obvious choice or remotelocations where concrete is more expensiveor just not accessible as well as areas withpoor oundations. his common and very

versatile shape is requently chosen orculverts, sewers and sub-drains, but it canalso be used or storage bins, access ways,tunnels, bridges, and storm water retention/detention systems.

THE STRONGEST: In mine sites aroundthe world, Super Cor is used underhuge stock piles.

Design and Installation

InstallationSuper Cor structures distributesuperimposed loads to the surrounding

engineered backill, so it is essentialto use care during installationand backilling to ensure properperormance. he ollowing guidelines

will help ensure a successul project.

Excavationrench excavation will vary, dependingon the nature o the in situ material.It is necessary to provide an excavatedarea that ensures adequate distancerom soils with questionable structural

integrity. I the native soil is stable,excavate only the area that is requiredto provide minimum bedding, backillenvelope and enough room orcompaction equipment to manoeuvre.For stream crossing applications, localauthorities will impose guidelines orconstruction activity.

FoundationsSuper Cor structures are lexible andcan accommodate some dierential

settlement without distress. It isimportant, nevertheless, to minimizedierential settlement by removingand replacing poor oundationmaterial. Pile oundations otencreate dierential settlement issues.Preparation should be conined tominimum, but practical, widths andshould result in a uniorm base orthe structure. A bedding o loosematerial will provide a slight cushionand the bedding may be lat or

shaped, depending on the structureconiguration and constructionmethods being used. It is essential thatall corrugations be illed.

AssemblyA SuperCor structure arrives atthe job site in bundles curved to the

proper radius. Included are bolts andany other special hardware that maybe required, as well as instructions andshop drawings listing all components.

Assembly is easy, requiring relativelysimple tools. Correct lapping, bolt-tightening and shape-monitoring areall important to achieve the correctdesign dimensions. Your AILrepresentative can provide inormationand assistance to those unamiliar

with structural plate assembly.

BackfillSuper Cor structures require a stable,engineered backill to retain theirshape and structural integrity. hequality o the backill envelope dependson the choice o material, placemento backill, and compaction o theenvelope. AIL will detail suitablebackill materials or the structures.

A well-graded, ree-draining, granularbackill is preerred. here is nosubstitute or an examination by ageotechnical engineer.

InspectionInspection should be perormed on aull-time basis by qualiied personnel.Backill is placed in a balanced mannerin 150mm (6") to 200mm (8") litsor the entire backill envelope.Compaction testing is requiredto ensure that backill material iscompacted to the required Standard

Proctor Density. It is a good ideato assess the compaction equipmentand have its use approved by thegeotechnical engineer or qualiiedinspector.

End FinishesSpecial attention must be paid tobeveled or skewed ends. Incomplete

structural rings may need to bereinorced with steel or concrete(or tied back) to maintain structuralintegrity. Exercise caution when placingbackill around them to avoid distortion.

Standard End Finishes are:

Squared

Beveled

Partially-beveled

Skewed

he CSPI Handbook o Steel Drainage& Highway Construction Products andthe NCSPA handbook provide a new,detailed section on backilling and thehydraulics o various steel structures.

Your AIL representative can provideyou with a copy o the handbook.
