Get Started
Tell Us What You Need.
Five quick things and we’ll call you back with a price. You don’t need the full spec in hand.
What We Can Get
Pipe, Structures, and Fittings.
From plain round pipe and coupling bands through to multi-plate arch runs with cast headwalls. If it can be drawn, it can be fabricated.








Specification
Quoted to CDOT Spec.
Gauge & Corrugation
16 gauge through 8 gauge, annular corrugation only — full rings rather than a spiral, so a coupling band seats on the corrugation right around the pipe. We don’t supply helical. Tell us the spec you’re building to and we’ll match it, odd gauges included.
Request PricingSizes
12″ to 96″. Metal is fabricated against the order rather than pulled from stock, so the diameter and length come off your plan, not off a size list. Round or arch, small driveway barrels through multi-plate spans.
Request PricingStructures
Headwalls, wingwalls, weir inlets, risers, trash racks, wyes and bands, fabricated to your drawing rather than picked off a shelf.
Request PricingPricing
16 gauge galvanized is priced per foot and per 20′ stick. Other gauges, aluminized and polymer-coated pipe are quoted per job, same day.

Which One for Your Job.
Both carry traffic and both last. The job usually picks for you: what the spec names, how big the span is, and what the water is carrying.
In stock, 12″ to 60″
On the yard in 20' lengths with belled gasketed ends, so no couplers and usually no wait.
Built to order
Fabricated against your spec, so lead time is real. Plan it into the schedule.
Won’t rust
No corrosion, no galvanic issues, nothing to coat.
Coatings for hard water
Galvanized, aluminized and polymer-coated options where abrasion or chemistry is the problem.
Light enough to place easily
A 20' section handles with equipment already on most sites.
Spans HDPE can’t
Arch sections and multi-plate runs go well beyond 60″, in shapes HDPE isn’t made in.
Priced and published
Sizes 12″ to 60″ are priced on the HDPE culvert page. No call needed to compare.
Meets agency spec
When CDOT, a county, or an irrigation district calls for metal by name, this is the line.
