Why Choose Steel Tanks for Bulk Liquid Storage?
✔ Superior Strength-to-Weight Ratio
While other tanks may be lighter, a properly designed steel tank offers the highest structural strength for its weight, making it the ideal material for high-volume liquid containment and extreme weather conditions.
✔ Fire-Resistant Material
Steel is a non-combustible material, making it the premier choice for fire protection. This is why our steel fire protection tanks are the only option for NFPA 22-compliant systems, as they are proven to provide reliable fire water storage.
✔ Corrosion-Resistant Options
Rust is a known concern, but we offer a range of solutions to eliminate it. Our galvanized steel tanks and stainless steel tanks are inherently corrosion-resistant, while our carbon steel tanks can be protected with custom coatings for a long-lasting, rust-free solution.
✔ Extensive Design Flexibility
We offer a variety of configurations to meet any project need. Our custom steel tanks come in welded, bolted, and corrugated panel designs, allowing us to accommodate tight site constraints, difficult transportation routes, and unique installation timelines.
