When designing long-lasting drainage and stormwater infrastructure, Corrugated Steel Pipe (CSP) continues to be a trusted solution for DOTs and public agencies. Known for its strength, flexibility, and proven performance, CSP delivers reliable structural capacity, and the right coating ensures that performance stands the test of time.
“Engineered protective coatings are the key to transforming corrugated steel pipe into a long‑life structural system, optimized for site‑specific soil, water, and abrasion environments.”
Brandon Scherber, TrueNorth Steel Sales Engineer
Coatings Protect Steel Where It Matters Most
Installed underground, CSP is exposed to soil chemistry, moisture, abrasion, and water flow. While steel provides the structural strength, coatings serve as the first line of defense against corrosion and wear.
Properly selected CSP coatings help:
- Resist corrosion from soil and water conditions
- Reduce abrasion from sediment and flow
- Extend service life and reduce maintenance
- Protect structural integrity over decades
Matching CSP Coatings to Site Conditions
No two installations are the same. Soil resistivity, pH levels, moisture content, and hydraulic conditions all impact pipe performance. That’s why coating selection should be based on the environment, not a one-size-fits-all approach. Common CSP coating options include:
- Zinc-Coated (Galvanized) for standard environments
- Polymer-coated systems for enhanced corrosion and abrasion resistance
- Aluminum and specialty coatings for aggressive soil and water conditions
“At TrueNorth Steel, we stand apart by combining expert guidance with a broad portfolio of coating solutions, ensuring each CSP installation is engineered for its specific site conditions,” Scherber says. “This approach helps agencies balance durability, performance, and cost while maximizing the lifespan of their infrastructure.”
Steel: The Stronger, Smarter and Sustainable Choice
Steel is recognized as a stronger and smarter material for infrastructure, offering high load capacity, flexibility under traffic, and proven performance in drainage applications. It is also 100% recyclable, maintaining strength and quality through repeated use. When CSP is paired with the right coating to extend service life, it supports sustainability goals by:
- Reducing material replacement cycles
- Lowering lifecycle environmental impacts
- Maximizing long-term value
At TrueNorth Steel, coatings are an integral part of our CSP solutions. We partner with DOTs, engineers, and contractors to evaluate site conditions and recommend coating systems designed to meet performance and service life expectations. With the right coating, Corrugated Steel Pipe remains a durable, sustainable, and cost-effective solution for drainage and stormwater infrastructure.
