Ameristar Stalwart
Ameristar Stalwart is a line of anti-ram vehicle barriers for critical infrastructure and high-risk sites, available as ornamental fence, mesh, fiber rope or post and rail.
About Ameristar Stalwart
Some perimeters need to stop a vehicle, not just a person. Ameristar Stalwart is a family of anti-ram vehicle barriers with multiple anti-ram ratings and a stand-off distance designed for each site. The framework can also act as a raceway for wiring, conduit and security cabling.
Five variants cover different design goals. Stalwart II combines an anti-ram barrier with ornamental fence. Stalwart IS integrates the barrier with Impasse II palisade fencing. Stalwart Optima uses fiber rope, Stalwart Plus pairs the barrier with architectural mesh, and Stalwart Post & Rail is a standalone anti-ram barrier. That range lets a security designer match the barrier to the look of the property.
Stalwart is aimed at critical infrastructure and other high-risk areas. Because ratings and stand-off are site-specific, quotes start from the project specification. Send the required rating, variant, perimeter length, site plan and any gate or cabling needs. Axiom South supplies the materials on an itemized quote and ships nationwide.
