Ship launching airbags are engineered with premium-quality rubber and reinforced with multiple layers of heavy-duty synthetic cord fabric. This combination delivers superior tensile strength and high elasticity. Available sizes include diameters from 1.0m to 3.0m and lengths from 6m to 20m. Each airbag undergoes strict pressure testing to ensure safety and performance in various marine conditions. Their portability and reusability make them a cost-effective solution for launching ships without permanent slipways, particularly suitable for coastal and river shipyards.
