Colewell Stainless Steel Marine Gas Struts are engineered specifically for the harsh marine environment. Unlike standard steel springs that rust quickly, our struts are constructed from premium 316-grade stainless steel, offering exceptional resistance to saltwater corrosion, pitting, and UV radiation.
Designed for boat hatches, engine covers, and livewell lids, these marine gas struts feature advanced sealing technology to prevent water ingress and maintain consistent lifting force. Whether for a small fishing boat or a luxury yacht, Colewell provides reliable, long-lasting motion control solutions.
Force Range | 100N - 3000N (approx. 10kg - 300kg). Adjustable force available. Capable of lifting heavy engine hatches and light deck lockers. |
Material Build | Cylinder & Rod: Full 316 Marine Grade Stainless Steel. Electropolished finish for maximum corrosion resistance and aesthetic appeal. |
Sealing Tech | Marine-grade fluororubber gaskets resist saltwater degradation and maintain nitrogen pressure even in high humidity. |
Operating Conditions | Temperature: -40℃ to +80℃. Salt Spray Test: >1000 Hours (ASTM B117). Suitable for tropical and arctic marine climates. |
We supply matching 316 stainless steel brackets and ball studs to ensure the entire assembly is rust-proof. Compatible with standard marine mounting patterns.
• Anti-Corrosion: 316 steel prevents structural failure due to rust.
• Hydraulic Damping: Prevents heavy hatches from slamming, protecting crew and fiberglass decks.
ISO 9001 manufacturing process. Meets marine industry standards for durability and safety (e.g., ABYC compliance).
• Dimensions: Custom lengths and strokes to fit specific hatch geometries.
• Force: Exact pressure calibration based on hatch weight.
• Locking: Optional locking tubes for added safety in rough seas.
Effortless Access: Supports heavy fiberglass or teak deck hatches, allowing easy access to storage and anchor lockers.
Heavy Lifting: Powerful struts lift heavy insulated engine covers, providing safe and hands-free maintenance access.
316 stainless steel resists saltwater rust and pitting, essential for ocean-going vessels.
Engineered to lift heavy hatches and covers with ease, ensuring reliable operation in rough seas.
Tested for 100,000+ cycles. Premium seals prevent gas loss even in extreme temperatures.
Self-lubricating design requires zero maintenance, ideal for hard-to-reach marine areas.
Prevents accidental hatch closure. Optional locking tubes available for added security.
We tailor length, force, and fittings to match your specific boat or yacht design.
Colewell is committed to quality and sustainability. Our marine gas struts are produced using eco-friendly processes and rigorous salt-spray testing.
We partner with leading yacht manufacturers to deliver reliable, corrosion-resistant solutions that withstand the toughest marine environments.
