GASTAC GTS Series Marine Gas Shock Specifications
Engineered for the Sea: GASTAC Marine Gas Struts
Marine gas shocks are significantly different from standard gas springs. Every component must be carefully selected to ensure long-term performance in corrosive environments. GASTAC marine gas shocks are engineered with premium materials that provide exceptional resistance against rust, moisture, and salt spray.
Key features include:
- Cylinders are manufactured using high-strength and precision seamless steel or stainless steel tubing.
- Carbon steel surfaces are hard chrome plated, while stainless steel incorporates 2%-3% molybdenum for enhanced corrosion resistance.
- Cycle life testing at full load conditions reaches 100,000 cycles or more.
- Smooth damping performance during extension and contraction, with no stick-slip phenomenon.
- Certified by ASTM B117 salt spray testing.
- Stable force output under a wide temperature range (e.g., -30°C to +80°C) without pressure fluctuation.
Stainlss Gas Shocks Applications Across the Marine Industry
GASTAC marine gas shocks are widely used by manufacturers and marine equipment suppliers around the world. Typical applications include:
Boat Engine Covers
Yacht Storage Compartments
Marine Access Doors
Deck Hatches
Fishing Boat Lids
Boat Window
Customized Solutions for Marine Gas Springs
No two marine applications are exactly the same. The size, weight, opening angle, mounting geometry, and operating environment all influence the performance of a marine gas shock. Instead of selecting a standard gas strut, GASTAC engineering team develops a customized solution based on your specific application. Let’s take a typical engine hatch as an example.
Example: Designing a Gas Shock for a Boat Engine Hatch
A customer approached us while developing a new fiberglass fishing boat. The engine hatch measured approximately 900 × 700 mm and weighed 28 kg. The hatch needed to open smoothly to approximately 75°, remain securely open during maintenance, and close without excessive operating force.
Rather than recommending a standard gas shock, our engineers began by evaluating several key parameters.
Step 1 – Analyze the Hatch Structure
GASTAC begin by conducting a comprehensive analysis of your CAD drawings to evaluate key engineering parameters—including hatch dimensions, total weight, center of gravity, hinge positioning, available installation space, and the required opening angle—all of which are critical to determining the precise lifting force and performance specifications for your specific application.
Step 2 – Calculate the Required Marine Gas Struts Force
Using the hatch weight, mounting geometry, and opening angle, our engineers calculated the optimum extension force. For this application, the required force was approximately 420 N per gas shock, ensuring the hatch could be opened comfortably while remaining stable in the fully open position.
Step 3 – Select the Correct Marine Gas Shock Dimensions
Once the force had been confirmed, the gas shock dimensions were optimized for the available installation space. Final specifications included:
- Extended Length: 520 mm
- Stroke: 210 mm
- Force: 420 N
- Rod Diameter: 10 mm
- Tube Diameter: 22 mm
- End Fittings: 10MM Ball Studs + Gas Spring Brackets
- Material: 316 Stainless Steel
The selected geometry ensured smooth movement throughout the opening cycle without interference.
Step 4 – Prototype Testing Marine Gas Shock
Before mass production, prototype samples were installed on the customer’s boat for functional testing. The engineering team evaluated:
- Opening effort
- Closing speed
- Holding force
- Full opening angle
- Installation clearance
- Long-term operating stability
Minor adjustments were made to the gas force before final approval.
Step 5 – Mass Production Marine Gas Shocks
After validation, production specifications were finalized. The customer also requested:
- Laser-engraved logo
- Custom part numbers
- Individual protective sleeves
- Export carton packaging
- Barcode labels
The result was a fully customized marine gas shock solution ready for OEM production.
