Why Customers Choose Extreme Tanks
When you need a fuel storage or transfer tank, you’re not just buying a product—you’re investing in reliability, craftsmanship, and partnership. Extreme Tanks has built its reputation on three core principles:
In-House Quality Control
Every manufacturing process—from design to final inspection—happens under one roof. This means complete accountability, superior TIG welding (not faster MIG methods), and meticulous pressure and leak testing on every tank.
Agile, Responsive Manufacturing
As a small, focused manufacturer, Extreme Tanks moves fast. Custom designs are built to your exact specifications with incredibly short lead times—and delivered on time and on budget. No excuses, no delays.
Relationship-Driven Service
From your first call to final delivery, you’ll work directly with our fabricators. We listen, we communicate, and we go the extra mile to ensure your needs are met with integrity and respect.

What to Look for When Choosing a Tank Manufacturer
Before you commit to a tank supplier, use this checklist to ensure you’re making the right choice:
- In-house manufacturing: Do they control every step, or do they outsource? Full control = full accountability.
- Welding method: Is it TIG (superior) or MIG (faster but weaker)? Ask specifically.
- Material quality: Are they using food-grade stainless steel and aircraft-grade aluminum, or cheaper alternatives?
- Testing protocols: Does every tank get pressure and leak tested before delivery?
- Lead times: Can they deliver quickly without sacrificing quality? Agile manufacturers move faster.
- Customization: Will they modify standard designs or build from scratch to your specs?
- Direct communication: Do you speak with fabricators or a sales department? Direct is better.
- Budget transparency: Do they quote upfront with no hidden fees or change orders?
- Industry experience: Have they worked with your industry (agriculture, aviation, landscaping, etc.)?
- Local availability: Can you visit their facility and see the work firsthand?
- References: Can they provide customer testimonials or case studies from similar projects?
- Support after delivery: Will they answer questions and provide guidance after your tank arrives?
Frequently Asked Questions
What materials do you use for your tanks?
We use food-grade 304L stainless steel and 5052 aircraft-grade aluminum. Both materials offer excellent corrosion resistance and durability. The choice depends on your specific application and budget. We’ll recommend the best material for your needs.
What size tanks do you offer?
Our standard AST fuel storage tanks range from 150 to 3,000 gallons. We also build custom tanks in virtually any size to fit your specific application. Call us to discuss your capacity requirements.
How long does it take to build a custom tank?
As a small, agile manufacturer, we offer incredibly short lead times compared to larger competitors. Most custom tanks are built and delivered within weeks, not months. Contact us with your specifications for a specific timeline.
What’s the difference between TIG and MIG welding?
TIG (Tungsten Inert Gas) welding produces stronger, cleaner, more precise welds. It’s slower than MIG (Metal Inert Gas) but superior in quality. We use TIG exclusively because fuel tanks demand the highest weld integrity. Cheaper manufacturers often use MIG to save time and money, but this compromises safety and durability.
Do you test every tank before delivery?
Yes. Every tank undergoes rigorous pressure and leak testing before it leaves our facility. We don’t ship anything we wouldn’t trust with our own fuel.
Can you build a tank for my truck bed?
Absolutely. We specialize in custom truck bed fuel tanks and auxiliary tanks. Whether you need a 100-gallon tank that fits below a tonneau cover or a custom configuration for gas or diesel, we can build it to your exact specifications.
What industries do you serve?
Our customers span agriculture, aviation, landscaping, waste management, manufacturing, and maintenance. If your industry requires fuel storage or transfer, we have experience and solutions for your needs.
Do you offer single or double-wall tanks?
We build both. Single-wall tanks are standard and cost-effective. Double-wall tanks provide extra protection against spills and leaks, which is important in environmentally sensitive applications. We’ll help you determine which is right for your situation.
Can you add custom features like baffles, manways, or sight glasses?
Yes. We offer a wide range of options including baffles, manways, sight glasses, lifting lugs, hose holders, hose reel brackets, fork pockets, and more. Tell us what you need, and we’ll design it into your tank.
What are your business hours?
Do you serve areas outside the Midwest?
Our primary service areas are Indiana, Michigan, Illinois, and Ohio. If you’re outside this region, contact us to discuss shipping options and logistics for your custom tank.
How do I get a quote for a custom tank?
Are your tanks food-safe?
Our standard tanks are built with food-grade 304L stainless steel, which meets food safety standards. However, if your application involves food storage or transfer, discuss your specific requirements with us to ensure full compliance.
