MARS. Bulletproof Steel

Civilian and military armor, military vehicles, armored cars, shooting galleries and anti-shock protection.

Steels specially designed for bulletproof in civilian or military applications.
Its composition provides a high protection with a significant minor weight.

MARS® from INDUSTEEL protection steels are worldwide recognized for the exceptional characteristics and for the quality of its production and manufacturer service.

Specially geared for a high impact resistance and projectiles penetration, MARS ® steels, has all been tested against the aggressive calibers to offer the most accurate protection.

Civilian applications

Vehicle, armored vans, high safety doors and windows for jewelry, banks and observation point protection.

Military applications

Veneering and floors of light and heavy vehicles frameworks, vessels construction, observation points, ammunition testing’s, explosions protection, bulletproof protection pieces and important shielding military applications.
