- QG High-bearing capacity airbags - the air bag with 6, 7 or 8 layers of cord fabric
- QS Super-high-bearing capacity airbags - the air bag with 9, 10 or more layers of cord
The standard diameter of ship launching marine airbags (D) varies such as 0.8m, 1.0m, 1.2m, 1.5m, 1.8m and 2.0m, 2.5 meters etc. The standard effective length of air bag (EL or L) is from 6m to 26m, which should be specified by the user. Other specification ship launching airbags also can be supplied upon request.
