Choose between space-saving vertical designs or high-capacity horizontal vessels. All tanks are engineered to ASME and UL standards.
Vertical Storage Tanks
- Space Saving: Small footprint, ideal for tight industrial areas.
- Gravity Feed: Easier to dispense fuel via gravity in some setups.
- Maintenance: 360° external access for inspection.
- Best For: Generator backup, chemical dosing, thermal storage.
Horizontal Storage Tanks
- High Capacity: Supports volumes up to 150,000L+.
- Low Profile: Better stability and less visual obstruction.
- Flexibility: Easy to compartmentalize for multiple fuel types.
- Best For: Retail gas stations (UST), large fuel depots (AST).

Safety & Compliance First
Our tanks are engineered to exceed the most rigorous international safety standards, protecting your business from environmental liability and operational risks.
🛡️ Secondary Containment (Double-Wall)
Constructed with an inner primary tank and an outer secondary shell. This "tank-within-a-tank" design prevents hazardous leaks from reaching the environment, ensuring full EPA compliance.
📡 Interstitial Leak Monitoring
The gap between walls (interstitial space) is continuously monitored by electronic sensors. Any breach in either wall triggers an immediate alarm, allowing for rapid response before a spill occurs.
🔥 Explosion-Proof & Fire Rated
For aboveground tanks, we offer UL 2085 protected designs featuring lightweight concrete insulation, capable of withstanding 2-hour hydrocarbon pool fires without failure.
UL 142 / UL 58
Steel Tank Fabrication
The gold standard for steel tanks. UL 58 covers underground (UST) structural integrity, while UL 142 regulates aboveground (AST) flammability and leakage safety.
UL 1746
Corrosion Protection
Certifies that our underground tanks (composite or jacketed) are immune to external soil corrosion, guaranteeing a service life of 30+ years without rust.
ASME Section VIII
Pressure Vessel Code
Manufactured under strict ASME quality control for pressure vessels. Crucial for industrial applications requiring high-pressure fuel handling.
Applications & Industries
From urban retail stations to harsh industrial environments, our tanks are deployed globally to support critical fuel infrastructure.
Gas Stations
High-volume SF double-layer underground tanks (UST) designed for commercial refueling and environmental compliance.
Mining & Remote
Rugged, skid-mounted aboveground tanks (AST) built to withstand harsh terrains and extreme weather conditions.
Fleet Refueling
Private turnkey fueling stations for logistics companies to lower operational costs and control fuel quality.
Backup Power
Reliable diesel storage for mission-critical generators in hospitals, data centers, and telecommunication sites.

Frequently Asked Questions
What is the production lead time for a custom 50,000L tank?
Standard production time is 15-20 working days after drawing approval. For custom explosion-proof or special alloy tanks, lead time may extend to 25-30 days. We also keep stock of standard sizes for immediate dispatch.
Are your tanks compatible with the new EPA regulations?
Yes. All our double-wall underground tanks (UST) feature interstitial spaces for leak detection, fully complying with US EPA 40 CFR Part 280 and European environmental standards for secondary containment.
Can you ship to my project site internationally?
We export to over 50 countries. Our logistics team handles packing (skid-mounted or containerized), customs clearance, and can arrange delivery to major ports worldwide. CIF/DDP terms are available.
What is the warranty period?
We provide a 30-year limited warranty against internal/external corrosion for our SF double-layer underground tanks, and a 1-year comprehensive warranty for all accessories (pumps, valves, sensors).
