When you need to store or transport fuel safely, choosing the right jerry can matters. The two main options—plastic and metal—each offer distinct advantages. Below, we compare their durability, portability, safety, cost and environmental impact to help you decide what best suits your needs.
Durability & Strength
Metal jerry cans, typically made from steel, are exceptionally robust and resistant to impacts. They’re well suited to harsh environments, heavy-duty use and scenarios where rough handling is expected. They’re also less likely to deform under load, though dents and scratched coatings can expose the metal to corrosion over time.
Quality plastic jerry cans are usually made from high-density polyethylene (HDPE), a tough, chemically resistant material designed to handle everyday knocks without rusting. HDPE is inherently resistant to many fuels and won’t corrode; look for UV-stabilised options for outdoor use and long-term durability. For a concise overview of HDPE’s properties, see Encyclopaedia Britannica’s summary of HDPE.
Weight & Portability
If portability is a priority, plastic jerry cans are the easier choice. At the same capacity, they’re often several kilograms lighter than metal, making them simpler to carry, lift into vehicles and maneuver—especially when full. This can be a real advantage for camping, boating or topping up small equipment.
Metal jerry cans are heavier but deliver excellent structural integrity. If your containers will face extreme conditions—such as serious off-roading or industrial use—the weight trade-off can be worth it.
Safety & Fuel Compatibility
Both plastic and metal jerry cans can store fuel safely when they’re purpose-built and used correctly. Metal cans offer superior fire resistance and are less likely to warp at high temperatures, but they can rust if coatings are damaged, potentially contaminating fuel.
Plastic cans won’t rust and are highly resistant to many chemicals, but lower-quality plastics may degrade with certain fuels or prolonged UV exposure. Plastic containers can also expand with heat, so avoid overfilling and store them out of direct sun where possible. Whichever material you choose, look for products that meet relevant safety standards (such as AS/NZS 2906 or UN/DOT approvals), include robust sealing caps and, ideally, flame-arresting or child-resistant spouts.

Cost & Availability
Plastic jerry cans are typically more affordable and widely available, offering excellent value for most everyday applications. Metal versions often cost more due to materials and manufacturing, but their long service life in demanding settings can justify the investment.
Environmental Considerations
Both materials can be part of a responsible, lower-impact choice when you buy quality and maintain your cans properly. HDPE jerry cans are lightweight (reducing transport emissions), long-lasting and recyclable at end of life. Steel jerry cans are also highly recyclable and can be repainted or refurbished to extend their lifespan. Proper storage and leak prevention are critical to minimizing environmental harm regardless of material.

Which One Is Right for You?
- Everyday use, camping, boating and general backup fuel: Choose quality plastic HDPE jerry cans for the best balance of weight, cost and corrosion resistance.
- Heavy-duty, off-road or industrial applications: Consider metal jerry cans for maximum impact resistance and heat tolerance.
- Long-term storage or hot environments: Prioritize certified containers with robust seals; metal offers better heat stability, while premium, UV-stabilised HDPE handles weathering and won’t rust.
For most users, high-quality plastic jerry cans provide the ideal mix of durability, affordability and convenience. If you’re comparing options, start with reputable, standards-compliant HDPE jerry cans designed for safe, efficient fuel storage.
