What Are Heavy Duty Gas Struts and How Do They Work?

Heavy duty gas struts are high-force gas springs that use compressed nitrogen and hydraulic oil inside a steel cylinder to provide lifting assistance and controlled motion. Their robust construction enables force outputs from around 450 N up to 5,000 N, making them ideal for heavy lids, hatches and access panels. The internal piston separates gas above and oil below, creating a damping effect as the rod extends and retracts. Design features include hardened piston rods, corrosion-resistant body coatings and precision seals to maintain consistent performance under load. These struts support and carefully lower heavy objects while preventing sudden closures, reducing operator strain and enhancing safety.
