According to DIN 7274, 0.9 mm canisters must be made of steel. To prevent rust on the inside, the container is coated with a fuel-resistant paint based on alkyd (solvent) and ammonia. The powder coating provides corrosion protection and a smooth finish. The wide vent hole allows for complete emptying in less than 25 seconds. Seamless welding ensures the handles are stable. The quick-release locking system is completely leak-proof in any position. UN approval marking certifies compliance with the regulations for the transport of dangerous goods. The date stamp on the lid shows the year/month of production. The globally patented safety pin system provides additional protection against inadvertent opening of the canister.
