Floating Airbags
SunHelm Marine is a company specializing in the R&D and manufacturing of marine buoyancy solutions. Its core products include ship lifting airbags, salvage flotation bags, caisson flotation systems, and marine operation protection equipment, widely used in ship repair, underwater salvage, bridge construction, and offshore engineering.
Constructed with high-strength composites, these products offer corrosion resistance, impact resistance, and high load capacity for demanding marine operations like heavy lifting and impact absorption in harsh offshore environments. Crucially cold-resistant, they maintain flexibility in extreme low temperatures (e.g., Russia, Northern Europe, Canada), absorbing ship impact energy to ensure safe buffering during docking and movement.
Since September 29, 2025, SunHelm has commenced production of EUDR-compliant marine airbags , becoming the first enterprise in China's industry to support this green initiative.
