What’s the Best Tank Material?

Carbon Steel

Carbon steel tanks provide a good cost-value ratio. They don’t demand top dollar but are dependable. However, the weight of the tanks requires them to be smaller and can influence the maneuverability of the truck.

Pros

• Durable
• Good value

Cons

• Heavy
• Prone to rusting and pitting, increasing maintenance costs

Stainless Steel

Stainless steel tanks are the biggest investment on the market. However, they are likely to last longer than the trucks on which they are used. Keep in mind that this is the heaviest option, so capacity and truck maneuverability will be impacted.

Pros

• Highest durability available
• Won’t rust

Cons

• Most expensive
• Heavy

Aluminum

The light weight of aluminum tanks means you can increase capacity and potentially use a driver that doesn’t have a CDL (if the truck’s GVW is 26,000 or lower). However, they do have the shortest life expectancy, so it may be necessary to replace the tank before you are ready to get rid of the truck. Aluminum is much more difficult to repair than steel.

Pros

• Lightweight
• Won’t rust

Cons

• Shortest life expectancy
• Wears easily and is difficult to repair
