Shelter door systems
Foam aluminum composite reduces the weight of shelter doors from 90 tons to 18 tons, and shortens the open-close cycle from 15 minutes to just 3 minutes. This dramatically improves operational readiness and response speed.

Composite armor systems
Foam aluminum is combined with ceramic plates, aramid fibers, and high-strength steel to form new-generation armor systems. Its energy absorption disperses kinetic energy from projectiles, reducing armor deformation and preventing penetration. This balances lightweight structure and high ballistic resistance.
