Steel cylinders are what most people picture when they think of a gas cylinder. They are heavier than aluminum, but they handle higher pressures, take more abuse, and cost less per litre of capacity. That makes them the standard choice for welding shops, restaurants with cylinder cabinets, large helium for events, draft beer rooms, and any job where the cylinder sits in one place and just needs to work for years. Our cylinders ship empty, ready for their first fill of helium, CO2, oxygen, welding gas, or any other compatible gas.
