2.5m Marine Airbags Shock Absorbing Corrosion Proof Long Lifespan Sturdy

Description

Ship Launching Balloons are heavy-duty marine airbags designed for safe and efficient vessel launching and recovery. Made from high-strength rubber with reinforced layers, they offer exceptional load capacity (up to 500 tons) while remaining cost-effective compared to traditional methods. These airbags are UV-resistant, abrasion-proof, and easy to deploy, making them ideal for shipyards and marine operations. Their flexibility allows smooth, controlled launches, reducing risks of hull damage. Whether for small boats or large ships, these balloons ensure a stable, economical, and eco-friendly solution.
