Grille Systems for Critical Protection
Developed in close collaboration with industry partners, our designs maintain the precise airflow, weight, and dimensional constraints required for modern armored vehicles, naval vessels, and heavy machinery.
Plymouth® Products used for Ballistic Grilles
Unlike conventional solid steel barriers, our sandwich grille systems utilize a proprietary laminated construction. By fusing armored steel, aluminum, aramid, and polyurethane into a single high-performance structure, we deliver enhanced impact resistance while improving aerodynamic flow and reducing component weight. Plymouth® custom engineers each system to balance protection levels with fluid dynamics, leveraging decades of global experience in special profiles and advanced materials. Our capabilities extend to comprehensive extrusion manufacturing in stainless steel, carbon steel, and titanium.
Our steel extrusions serve as the structural backbone for high-integrity grille systems. We deliver precision-engineered profiles that ensure ballistic resilience while minimizing aerodynamic drag and overall vehicle weight.
